Background Bunyamwera(BUNV) and Ngari (NGIV) viruses are arboviruses of medical importance globally, the viruses are endemic in Africa, Aedes(Ae) aegypti and Anopheles(An) gambiae mosquitoes are currently competent vectors for BUNV and NGIV respectively. Both viruses have been isolated from humans and mosquitoes in various ecologies of Kenya. Understanding the risk patterns and spread of the viruses necessitate studies of vector competence in local vector population of Ae. simpsoni sl which is abundant in the coastal region. This study sought to assess the ability of Ae. Simpsoni sl mosquitoes abundant at the Coast of Kenya to transmit these viruses in experimental …

Whitefly-Induced Tomato Volatiles Enhance The Virulence Of Lecanicillium Lecanii, Yongwen Lin, Jinhua Huang, Komivi S. Akutse
All Peer-Reviewed Publications
Entomopathogenic fungi (EPF) are a group of microorganisms that have potential for replacing synthetic chemical pesticides. However, EPF virulence is often insufficient, and therefore adoption of EPF biopesticides has been relatively limited. Previous studies have shown that herbivore-induced plant volatiles (HIPVs) promoted the virulence of Lecanicillium lecanii, and that extracellular proteases and chitinases are important virulence factors of entomopathogenic fungi. We therefore put forward the hypothesis that HIPVs promote L. lecanii virulence by inducing extracellular protease or/and chitinase activity. Lecanicillium lecanii was treated with tomato HIPVs induced by various numbers/densities of Bemisia tabaci, the effect of HIPVs on L. lecanii …

Animals with small nervous systems may be prone to limitations in processing ability when confronted with a diversity of stimuli, especially if these involve multiple sensory modalities. We investigated the effect of the odour of the plant Lantana camara and its dominant volatile compound, β-caryophyllene, on the prey choice decisions of Evarcha culicivora, a jumping spider (Salticidae) that frequently visits L. camara as a site to mate and to obtain nectar. Evarcha culicivora expresses a strong preference for blood-fed female Anopheles mosquitoes as prey. We tested juvenile and adult E. culicivora in experiments involving live prey, lures made from dead …

Molecular Phylogeny Of Cave Dwelling Eremogryllodes Crickets (Orthoptera, Myrmecophilidae) Across Zagros Mountains And Southern Iran, Mohadeseh Sadat Tahami, Mina Hojat-Ansari, Anna Namyatova, Saber Sadeghi
International Journal of Speleology
Recently, several new species and subspecies from the genus Eremogryllodes Chopard, 1929 (Insecta: Orthoptera: Myrmecophilidae) inhabiting caves of Iran, have been described based on morphology. The high variation of genitalia structure along with high similarity of external morphology between populations hamper the precise species identification. Thus, molecular approaches are critical to determine the taxonomic positions of species/subspecies of this genus. Here we provide the molecular phylogeny, based on the 16S rRNA mitochondrial gene, of recently described species of Eremogryllodes along with some unidentified specimens from the same region. The results support the monophyly of the family Myrmecophilidae. The topology of …

The Philippine Agricultural Scientist
The lanzones scale insect, Unaspis mabilis Lit & Barbecho (Hemiptera: Diaspididae), is reported to infest cacao trees (Theobroma cacao) in Brgy. Nalook, Kalibo, Aklan. Despite minor morphological differences, analysis of DNA barcode region of the cytochrome c oxidase subunit I (COI) generated from the cacao-infesting scale insects (GenBank Accession Number MN114100.1) matched the DNA barcodes obtained from a complementary study (GenBank Accession Number MN114099), and hence, supported the species identity based on morphological characters. Notes on the distribution, host plant association and insights on possible control measures were provided.

Impact Of Maize Hormonal Interactions On The Performance Of Spodoptera Frugiperda In Plants Infected With Clavibacter Michiganensis Subsp. Nebraskensis, Karen Da Silva, Sydney E. Everhart, Joe Louis
Department of Entomology: Faculty Publications
In nature, plants interact with multiple organisms, below and aboveground. Although interactions of plants with single biotic stressors are well characterized, knowledge of how the immune system responds to multiple biotic stressors is lacking. It is known that the two most important pathways involved in the plant immune defenses are jasmonic acid (JA) and salicylic acid (SA). The crosstalk between these plant hormonal signaling pathways seems to fine-tune the plant responses to different stressors. In this study, we characterized maize (Zea mays) hormonal interactions under the attack of two economically important pests: the bacterial pathogen that causes Goss’s …

Naviauxella Horii, A New Tiger Beetle Species From Myanmar (Coleoptera: Cicindelidae), Jürgen Wiesner, Moe Hnin Phyu
Insecta Mundi
Naviauxella horii Wiesner and Phyu, new species (Coleoptera: Cicindelidae), is described. It is distinguished from the other members of the genus by shape of the aedeagus and shape of the elytral maculation.
Due to the kindness of Michio Hori, we were able to study specimens of a tiger beetle species he recently collected in Myanmar. It proved to be new to science and is described herein. It is a member of the genus Naviauxella Cassola, 1988, which raises the number of species in this genus to 22 (Wiesner 2020: 264).
Emarginoptyx Ballantyne (Coleoptera: Lampyridae: Luciolinae), A Replacement Name For The Firefly Genus Emarginata Ballantyne, 2019, Lesley Ballantyne, Oliver Keller
Emarginoptyx Ballantyne (Coleoptera: Lampyridae: Luciolinae), A Replacement Name For The Firefly Genus Emarginata Ballantyne, 2019, Lesley Ballantyne, Oliver Keller
Insecta Mundi
Emarginata Ballantyne, 2019 (Coleoptera: Lampyridae: Luciolinae), is found to be a junior homonym of the bird genus Emarginata Shelley, 1896 (Avis: Passeriformes: Muscicapidae). The new replacement name Emarginoptyx Ballantyne is provided for the SE Asian genus Emarginata Ballantyne, leading to one new combination, Emarginoptyx trilucida (Jeng, Yang and Lai, 2003).
It has come to our attention that the name Emarginata Ballantyne in Ballantyne et al. (2019) for Emarginata trilucida (Jeng, Yang and Lai, 2003), is preoccupied by Emarginata Shelley, a genus of birds from southern Africa (Shelley 1896).

Luciola Lambkinae Keller And Ballantyne, New Replacement Name For Luciola Roseicollis Pic, 1935 (Coleoptera: Lampyridae), Oliver Keller, Lesley Ballantyne
Insecta Mundi
Two different species descriptions for Luciola roseicollis by Pic (Coleoptera: Lampyridae) are compared, and a replacement name, Luciola lambkinae Keller and Ballantyne nomen novum, for Luciola roseicollis Pic, 1935 is proposed.
In McDermott’s (1966) catalog of the family Lampyridae two citations are listed under the heading Luciola roseicollis Pic, 1933. Both articles include descriptions of L. roseicollis and also the statement that they are new species (Pic 1933, 1935). After comparing both descriptions OK contacted LB with the suspicion that the descriptions are about two different species.

The gut microbiome plays an important role in a host’s development and adaption to its dietary niche. In this study, a group of bamboo-feeding insects are used to explore the potential role of the gut microbiota in the convergent adaptation to extreme diet specialization. Specifically, using a 16S rRNA marker and an Illumina sequencing platform, we profiled the microbial communities of 76 gut samples collected from nine bamboo-feeding insects, including both hemimetabolous (Orthoptera and Hemiptera) and holometabolous (Coleoptera and Lepidoptera) species, which are specialized in three distinct dietary niches: bamboo leaf, shoot, and sap. The gut microbiota of these insects …

Tomato chlorosis virus (ToCV), is one of the most devastating cultivated tomato viruses, seriously threatened the growth of crops worldwide. As the vector of ToCV, the whitefly Bemisia tabaci Mediterranean (MED) is mainly responsible for the rapid spread of ToCV. The current understanding of tomato plant responses to this virus and B. tabaci is very limited. To understand the molecular mechanism of the interaction between tomato, ToCV and B. tabaci, we adopted a next-generation sequencing approach to decipher miRNAs and mRNAs that are differentially expressed under the infection of B. tabaci and ToCV in tomato plants. Our data revealed …

Variation in vector traits can modulate local scale differences in pathogen transmission. Here, we compared seasonal variation in the wing length (proxy for body size) and energy reserves of adult wild-caught Aedes aegypti populations from a dengue endemic (Kilifi) and non-endemic (Isiolo) area of Kenya. Vector sampling in the dengue endemic site was conducted during the dry and wet seasons. In the non-endemic area, it was limited to the dry season which characterizes this ecology where sporadic or no rainfall is commonplace during the year. We found variation by site in the body size of both sexes, with an overall …

The molecular mechanisms of insect resistance to Cry toxins generated from the bacterium Bacillus thuringiensis (Bt) urgently need to be elucidated to enable the improvement and sustainability of Bt-based products. Although downregulation of the expression of midgut receptor genes is a pivotal mechanism of insect resistance to Bt Cry toxins, the underlying transcriptional regulation of these genes remains elusive. Herein, we unraveled the regulatory mechanism of the downregulation of the ABC transporter gene PxABCG1 (also called Pxwhite), a functional midgut receptor of the Bt Cry1Ac toxin in Plutella xylostella. The PxABCG1 promoters of Cry1Ac-susceptible and Cry1Ac-resistant strains were …

Varroa mites (Varroa destructor) are parasitic mites that, combined with other factors, are contributing to high levels of honey bee (Apis mellifera) colony losses. A Varroa-active dsRNA was recently developed to control Varroa mites within honey bee brood cells. This dsRNA has 372 base pairs that are homologous to a sequence region within the Varroa mite calmodulin gene (cam). The Varroa-active dsRNA also shares a 21-base pair match with monarch butterfly (Danaus plexippus) calmodulin mRNA, raising the possibility of non-target effects if there is environmental exposure. We chronically exposed the entire monarch …

Worldwide, French beans (Phaseolus vulgaris L.), tomato (Solanum lycopersicum L.), and kales (Brassica oleracea L. var. acephala) are considered economically important food crops. There is a rapid decline in their yield due to severe soil degradation. Thus, high commercial fertilizer inputs are crucial, though they remain expensive and inaccessible to resource poor farmers. We investigated the comparative performance of composted black soldier fly frass fertilizer (BSFFF), conventionally composted brewer's spent grain (BSG), commercial organic fertilizer (Evergrow), and mineral [nitrogen, phosphorus, and potassium (NPK)] fertilizer on growth, yield, N use efficiency, and nutritional quality (crude protein, crude fiber, crude fats, ash, …

Conservation of North America's eastern monarch butterfly (Danaus plexippus) population would require establishment of milkweed (Asclepias spp.) and nectar plants in the agricultural landscapes of the north central United States. A variety of seed-treatment and foliar insecticides are used to manage early- and late-season pests in these landscapes. Thus, there is a need to assess risks of these insecticides to monarch butterfly life stages to inform habitat conservation practices. Chronic and acute dietary toxicity studies were undertaken with larvae and adults, and acute topical bioassays were conducted with eggs, pupae, and adults using 6 representative insecticides: beta-cyfluthrin …

Stink bugs represent an increasing risk to soybean production in the Midwest region of the United States. The current sampling protocol for stink bugs in this region is tailored for population density estimation and thus is more relevant to research purposes. A practical decision-making framework with more efficient sampling effort for management of herbivorous stink bugs is needed. Therefore, a binomial sequential sampling plan was developed for herbivorous stink bugs in the Midwest region. A total of 146 soybean fields were sampled across 11 states using sweep nets in 2016, 2017, and 2018. The binomial sequential sampling plans were developed …

An increase in returns from agriculture as a result of new or improved technology is often perceived to escalate women's loss of control over agricultural production and ability to make marketing decision due to persistent gender disparities in access to production resources. The International Centre of Insect Physiology and Ecology (ICIPE) and partners have developed integrated pest management (IPM) technology to suppress mango fruit flies on smallholder mango farm in sub-Saharan Africa.

The fall armyworm (FAW), Spodoptera frugiperda (J.E. Smith), which has recently invaded the African continent, has become a new threat to cereal production. Being an invasive pest with certain competitive advantages, the impact of FAW on other lepidopteran pests is unclear. This study assessed the infestation of FAW and cereal stemborers on maize and sorghum under mono-cropped systems that are adjacently placed in five districts in Uganda. Data on maize and sorghum infestation cereal stemborers and FAW was collected at 6, 9 and 16 weeks after planting (WAP), to determine intensity and severity. Cereal stemborer infestations on maize at 6, …

Worldwide, stored products are attacked by a large number of pests resulting in significant economic losses. Among these stored grain pests, khapra beetle, Trogoderma granarium (Everts) (Coleoptera: Dermestidae) is one of the top ranked pests that has ability to survive under diverse climate conditions. The management of this pest is mainly done by using synthetic chemicals which have side effects on consumers, ecosystem and non-target organisms. However, phyto-derivatives were found to be the effective environment friendly alternatives against T. granarium. Therefore, in this review, success of phyto-derivatives against khapra beetle from conventional means to modern research has been critically analyzed, …

Fall armyworm, Spodoptera frugiperda (J. E. Smith) has rapidly spread in sub-Saharan Africa (SSA) and has emerged as a major pest of maize and sorghum in the continent. For effective monitoring and a better understanding of the bioecology and management of this pest, a Community-based Fall Armyworm Monitoring, Forecasting, Early Warning and Management (CBFAMFEW) initiative was implemented in six eastern African countries (Ethiopia, Kenya, Tanzania, Uganda, Rwanda and Burundi). Over 650 Community Focal Persons (CFPs) who received training through the project were involved in data collection on adult moths, crop phenology, cropping systems, FAW management practices and other variables. Data …

Background Riverine tsetse (Glossina spp.) transmit Trypanosoma brucei gambiense which causes Gambian Human African Trypanosomiasis. Tiny Targets were developed for cost-effective riverine tsetse control, and comprise panels of insecticide-treated blue polyester fabric and black net that attract and kill tsetse. Versus typical blue polyesters, two putatively more attractive fabrics have been developed: Vestergaard ZeroFly blue, and violet. Violet was most attractive to savannah tsetse using large targets, but neither fabric has been tested for riverine tsetse using Tiny Targets. Methods We measured numbers of G. f. fuscipes attracted to electrified Tiny Targets in Kenya and Uganda. We compared violets, Vestergaard …
