Genetic Connectivity Of Trypanosomes Between Tsetse-Infested And Tsetse-Free Areas Of Kenya, Naomi N. Kimenyi, Kelvin M. Kimenyi, Nelson O. Amugune, Merid N. Getahun
All Peer-Reviewed Publications
The prevalence rates of trypanosomes, including those that require cyclical transmission by tsetse flies, are widely distributed in Africa. Trypanosoma brucei and Trypanosoma congolense are actively maintained in regions where there are no tsetse flies although at low frequencies. Whether this could be due to an independent evolutionary origin or multiple introduction of trypanosomes due to continuous movement of livestock between tsetse-free and -infested areas is not known. Thus, the aim of the study was to carry out microsatellite genotyping to explore intra-specific genetic diversity between T. (Trypanozoon), T. congolense and Trypanosoma vivax from the two regions: tsetse infested and …

Biology Faculty Publications
Background
The STECLA strain of Anopheles albimanus has been in continuous colony for many years and is the reference strain on which genomic studies for the species are based. Recently, the STECLA strain was demonstrated to be much less susceptible to ivermectin ingested in a blood meal (4-day LC50 of 1468 ng/ml) than all other Anopheles species tested to-date (LC50 values range from 7 to 56 ng/ml). The ability of An. albimanus to survive ingestion of ivermectin at concentrations far beyond that typically found in the blood of ivermectin-treated people or livestock (i.e., 30–70 ng/ml) could invalidate the use of …

Effect Of Workers Density On Insect Pest Incidence And Colony Development Of Bumblebees, Bombus Terrestris (L.) (Hymenoptera: Apidae), Marium Fatima, Asim Gulzar, Munir Ahmed, Farid Asif Shaheen, Muhammad Tariq, Tariq Mukhtar
The Philippine Agricultural Scientist
Insect pollination improves essential nutrients and qualities of pollinating plants. Approximately 90% of flowering plants and 35% of crops require insect pollination. Bees play a vital role in pollination in natural and agricultural systems. Managed bees have extensively been used for pollination. Unfortunately, the native bee population has been waning globally. Commercial bee-rearing experiences different rearing problems i.e. food, environment, and spatial conditions within colonies. In this research, the impact of different densities of workers within colonies of Bombus terrestris L. was observed on colony development and pest incidence. Different worker densities i.e. 60-70, 80-90,110-120 and 140-150, respectively, were maintained …
Insecticide Resistance In Aedes Aegypti Varies Seasonally And Geographically In Texas/Mexico Border Cities, Heather Hernandez, Flor A. Martinez, Christopher Vitek
Insecticide Resistance In Aedes Aegypti Varies Seasonally And Geographically In Texas/Mexico Border Cities, Heather Hernandez, Flor A. Martinez, Christopher Vitek
School of Integrative Biological & Chemical Sciences (Formerly Dept. of Biology)
Insecticide use is the primary method of attempting to reduce or control the spread of mosquito-borne diseases. Insecticide resistance is a major concern as resistance will limit the efficacy of vector-control efforts. The lower Rio Grande Valley region of South Texas has had autochthonous transmission of multiple mosquito-borne diseases including those caused by dengue virus, chikungunya virus, and Zika virus. However, the current status of mosquito resistance to commonly used pesticides in this region is unknown. In this study, we collected field samples from multiple municipalities in South Texas and assessed resistance using the Centers for Disease Control and Prevention …

Wild swarms of the long-horned grasshoppers Ruspolia differens (Serville) which are widely harvested for consumption and sale in Africa are seasonal and unsustainable, hence the need for innovative ways of artificially producing the insects. We investigated the development, survival, and reproduction of R. differens in the laboratory on diets mixed with host plants [Digitaria gayana Kunth, Cynodon dactylon (L.) and Megathyrsus maximus Jacq (Poales: Poaceae); Ageratum conyzoides L. (Asterales: Asteraceae)] identified from guts of their wild conspecifics with a view to developing a suitable diet for artificial mass rearing of the edible insect. A standard diet comprising ground black soldier …

Increased demand for animal protein has motivated the search for more efficient livestock production systems. In recent years, there has been growing interest to incorporate insect meal as an alternative source of protein to fish/soybean meal in chicken feed for improved nutrition, sustainability, and animal welfare benefits. Black soldier fly larval (BSFL)-based feeds has been shown to increase egg production in a cost-effective manner. However, poultry consumers perception towards the consumption of eggs from layers fed diet integrated with BSFL-based meal have received limited research attention. This study evaluates consumers’ perception towards eggs from hens fed BSFL-based diets and socioeconomic …

Tephritid fruit flies are considered one of the world’s most notorious pests of horticultural crops, causing extensive direct and indirect damage. Over the past two decades, a comprehensive, integrated pest management (IPM) package for the management of a plethora of fruit fly pests, includ-ing Bactrocera dorsalis, B. latifrons, B. zonata, Ceratitis cosyra, C. rosa, C. fasciventris, C. quilici, C. capitata, Dacus spp. and Zeugodacus cucurbitae, has been developed, disseminated and promoted among horticultural growers in Africa. To estimate the numbers of beneficiaries reached by the fruit fly IPM technology and the barriers to technology uptake, we interviewed 290 experts in …
Non-Native Non-Apis Bees Are More Abundant On Non-Native Versus Native Flowering Woody Landscape Plants, Daniel A. Potter, Bernadette M. Mach
Non-Native Non-Apis Bees Are More Abundant On Non-Native Versus Native Flowering Woody Landscape Plants, Daniel A. Potter, Bernadette M. Mach
Entomology Faculty Publications
Urban ecosystems can support diverse communities of wild native bees. Because bloom times are conserved by geographic origin, incorporating some non-invasive non-native plants in urban landscapes can extend the flowering season and help support bees and other pollinators during periods when floral resources from native plants are limiting. A caveat, though, is the possibility that non-native plants might disproportionately host non-native, potentially invasive bee species. We tested that hypothesis by identifying all non-native bees among 11,275 total bees previously collected from 45 species of flowering woody landscape plants across 213 urban sites. Honey bees, Apis mellifera L., accounted for 22% …

Bees provide an important ecosystem service by contributing to the pollination of crop and wild plant species. Many factors have been attributed to bee declines, including habitat loss, improper apiary management, pesticide usage, climate change, pests and pathogens, competition among native and introduced bee species, poor nutrition, and other factors (Koh et al., 2016; Goulson et al., 2015; Graves et al., 2020; Soroye et al., 2020). Acting together, these factors intensify the pressure for survival beyond the adaptability of many species. This fact sheet reviews the factors contributing to decline in bee populations and what can be done to protect …

There is interest in developing controlled release materials (CRMs) with novel modes of action to improve resistance management. Long-lasting insecticide-incorporated netting (LLIN) with deltamethrin has been effectively used against stored-product pests. Here, we evaluated the efficacy of different CRMs (LLIN or packaging) with each of four active ingredients (AI) (deltamethrin, permethrin, indoxacarb, and dinotefuran) and compared them to control CRMs in reducing movement and increasing mortality of phosphine-susceptible and -resistant Rhyzopertha dominica and Tribolium castaneum. Adults were exposed for 0.5, 2, or 60 min, and movement was assessed immediately or after 24, or 168 h using video-tracking and Ethovision …

Entomology Faculty Publications and Presentations
Reactive oxygen species (ROS) such as hydrogen peroxide and superoxide are produced in plants in response to many biotic and abiotic stressors, and they can enhance stress adaptation in certain circumstances or mediate symptom development in others. The roles of ROS in plant-pathogen interactions have been extensively studied, but far less is known about their involvement in plant-insect interactions. A growing body of evidence, however, indicates that ROS accumulate in response to aphids, an economically damaging group of phloem-feeding insects. This review will cover the current state of knowledge about when, where, and how ROS accumulate in response to aphids, …

Biosecurity Research Articles
Spodoptera frugiperda (J.E. Smith) is a highly invasive noctuid pest first reported in northern Australia during early 2020. To document current status of resistance in S. frugiperda in Australia, insecticide toxicity was tested in field populations collected during the first year of establishment, between March 2020 and March 2021. Dose-response was measured by larval bioassay in 11 populations of S. frugiperda and a susceptible laboratory strain of Helicoverpa armigera. Emamectin benzoate was the most efficacious insecticide (LC50 0.023μg/ml) followed by chlorantraniliprole (LC50 0.055μg/ml), spinetoram (LC50 0.098μg/ml), spinosad (LC50 0.526μg/ml), and methoxyfenozide (1.413μg/ml). Indoxacarb was the least toxic …

EEB Articles
Background: The northern metalmark (Calephelis borealis), is an exceedingly local, globally rare butterfly that is declining across the Midwestern and Northeastern USA. The principal stressors driving colony losses include afforestation and invasive plants that crowd out its larval hostplant (Packera ovata) and nectar resources.
Aims/Methods: To better understand its declines and guide restoration efforts, we 1) performed a mark-recapture study in Connecticut to document population trends where we were actively managing vegetation; 2) conducted a range-wide survey for evidence of phylogeographic structure, using cytochrome oxidase (CO1); 3) investigated abundance determinants of its larval foodplant, Packera ovata …
