Light And Dark Rhythms Of Pupal Eclosion And Egg Hatching In Tropical Stem Borers’ Moths, Paul André Calatayud, François Rebaudo, Peter Ahuya, Bruno Le Ru

All Peer-Reviewed Publications

Different traits in insects such as locomotor activity, egg-hatching, emergence from puparia and oviposition follow light and dark rhythms. In noctuid stemborer moths, activity cycles of the adults linked to their reproductive traits concentrate at the first half of the night and some of them are highly species specific. However, little information is available on the light and dark rhythm of egg hatching in noctuid stemborer moths as compared to adult’s activities (emergence, oviposition and mating). The purpose of this study was to compare the light and dark rhythms of pupal eclosion and egg hatching, respectively, for four main species …

Subsequent Spelling Cavolinii For Scarabaeus Cavolini Petagna, 1792 (Currently Copris Hispanus Cavolinii) To Be Maintained As Prevailing Usage (Coleoptera: Scarabaeoidea: Scarabaeidae: Coprini), Stefano Ziani

Insecta Mundi

The specific name in Scarabaeus cavolinii Petagna, 1792 (currently Copris hispanus ssp. cavolinii) (Coleoptera: Scarabaeidae: Coprini) is an incorrect subsequent spelling—the original spelling is cavolini—but, because of its prevailing usage here documented, is to be preserved.

In 1792, Petagna described Scarabaeus cavolini (Coleoptera: Scarabaeidae) as a tribute to the famous Italian biologist Filippo Cavolini (1756–1810), whose Latinized name was Philippus Cavolinus (Petagna 1785; Smith 1804). To dedicate the new species to him, Petagna (1792) declined the name to the genitive singular case of the second Latin declension, which is Cavolini.

The original spelling “cavolini” was …

Identification Of Planthoppers (Hemiptera: Delphacidae) Intercepted On Aquarium Plants In Florida And Elucidation Of A Potential Pathway For Exotic Aquatic And Semiaquatic Pests, Susan E. Halbert, Matthew R. Moore, Charles R. Bartlett, Jade S. Allen

Insecta Mundi

Recent shipments of aquarium plants to pet stores in five Florida counties were found to be infested with an exotic delphacid planthopper. Rearing adult males allowed identification by morphological analysis. Molecular analysis confirmed that it was the same as authoritatively identified reference specimens of the planthopper, Opiconsiva anacharsis (Fennah) (new combination) (Hemiptera: Delphacidae), first reported from Florida in 1989 and known to be established only in Broward County. The host plants, Echinodorus spp. Rich. ex Engelm. (Alismatales: Alismataceae), originally from Thailand, were sold in enclosed plastic cylinders that provided a suitable environment for maintaining the planthoppers. Attempts to trace the …

Integrating Gwas And Transcriptomics To Identify The Molecular Underpinnings Of Thermal Stress Responses In Drosophila Melanogaster, Melise C. Lecheta, David N. Awde, Thomas S. O’Leary, Laura N. Unfried, Nicholas A. Jacobs, Miles H. Whitlock, Eleanor Mccabe, Beck Powers, Katie Bora, James S. Waters, Heather J. Axen, Seth Frietze, Brent L. Lockwood, Nicholas M. Teets, Sara H. Cahan

Entomology Faculty Publications

Thermal tolerance of an organism depends on both the ability to dynamically adjust to a thermal stress and preparatory developmental processes that enhance thermal resistance. However, the extent to which standing genetic variation in thermal tolerance alleles influence dynamic stress responses vs. preparatory processes is unknown. Here, using the model species Drosophila melanogaster, we used a combination of Genome Wide Association mapping (GWAS) and transcriptomic profiling to characterize whether genes associated with thermal tolerance are primarily involved in dynamic stress responses or preparatory processes that influence physiological condition at the time of thermal stress. To test our hypotheses, we …

Histone Deacetylase 3 Is Required For Development And Metamorphosis In The Red Flour Beetle, Tribolium Castaneum, Smitha George, Subba Reddy Palli

Entomology Faculty Publications

Background

Hormones are chemical communication signaling molecules released into the body fluids to stimulate target cells of multicellular organisms. We recently showed that histone deacetylase 1 (HDAC1) plays an important role in juvenile hormone (JH) suppression of metamorphosis in the red flour beetle, Tribolium castaneum. Here, we investigated the function of another class I HDAC member, HDAC3, and show that it is required for the normal development of T. castaneum.

Results

RNA interference-mediated knockdown of the HDAC3 gene affected development resulting in abnormally folded wings in pupae and adults. JH analog, hydroprene, suppressed the expression of HDAC3 in …

Invasive Paper Wasp Turns Urban Pollinator Gardens Into Ecological Traps For Monarch Butterfly Larvae, Adam M. Baker, Daniel A. Potter

Entomology Faculty Publications

Invasive species can be particularly disruptive when they intersect with organisms of conservation concern. Stabilizing the declining eastern migratory population of monarch butterflies (Danaus plexippus) is projected to require extensive habitat restoration across multiple land use sectors including metropolitan areas. Numerous conservation programs encourage urban citizens to plant gardens with milkweeds, the obligate larval host plants of the monarch. Here, we show that predation by Polistes dominula, an invasive paper wasp that is particularly abundant in urban settings, can turn such sites into ecological traps for monarch larvae. Polistes dominula was the predominant paper wasp seen foraging …

Alfalfa Weevil In Utah, Kaitlin Rim, Joseph Clarine, Steven Price, Ricardo Ramirez

All Current Publications

The alfalfa weevil is a major pest throughout Utah. It is a beetle with one generation per year. Eggs hatch in the spring, and the grub-like immature weevils (larvae) feed by chewing on the alfalfa foliage. In high numbers, alfalfa weevils can cause severe damage to Utah alfalfa. In any given year, however, the weevils are few enough in number in many fields to cause only minor damage. Monitor larval populations in early spring using sweep net or stem count methods. Insecticide resistance can be reduced by spraying only when needed, properly timing sprays, and rotating between modes of action.

Cellular And Molecular Targets Of Waterbuck Repellent Blend Odors In Antennae Of Glossina Fuscipes Fuscipes Newstead, 1910, Souleymane Diallo, Mohd Shahbaaz, Baldwyn Torto, Alan Christoffels, Daniel Masiga, Merid N. Getahun

All Peer-Reviewed Publications

Insects that transmit many of the world’s deadliest animal diseases, for instance trypanosomosis, find their suitable hosts and avoid non-preferred hosts mostly through olfactory cues. The waterbuck repellent blend (WRB) comprising geranylacetone, guaiacol, pentanoic acid, and δ-octalactone derived from waterbuck skin odor is a repellent to some savannah-adapted tsetse flies and reduces trap catches of riverine species. However, the cellular and molecular mechanisms associated with detection and coding of the repellent odors remain to be elucidated. Here, we demonstrated that WRB inhibited blood feeding in both Glossina pallidipes Austen, 1903 and Glossina fuscipes fuscipes Newstead, 1910. Using the DREAM (Deorphanization …

Preparing To Cocreate: Using Learning Circles To Readyextension Professionals For Meaningful Stakeholderengagement, Bob Bertsch, Jill Heemstra, Doug Golick

Department of Entomology: Faculty Publications

Extension professionals are being asked to address complex public issues. Doing so requires cocreativeapproaches that engage, in a significant way, the people affected by these issues. Successful engagement,however, requires specific skills and a cocreative mind-set. Extension professionals in two states participatedin learning circles to improve their engagement skills. Using a survey and interviews, we studied the impact ofthe learning circle experience on participants. We found that learning circles helped participants practicecolearning, build relationships, and change their mind-sets in ways that could move their work toward morecocreative efforts.

The Comparative Virulence Of An Atoxigenic Strain Of Aspergillus Flavus (Eurotiales: Trichocomaceae) And The Commercial Icipe 69 Metarhizium Anisopliae (Hypocreales: Clavicipitaceae) To The Bean Leaf Beetle Ootheca Mutabilis (Coleoptera: Chrysomelidae), Julius Mugonza, Michael H. Otim, James P. Egonyu

All Peer-Reviewed Publications

The recent isolation of an atoxigenic strain of Aspergillus flavus (Link) (Eurotiales: Trichocomaceae), which was virulent to all stages of Xylosandrus compactus (Eichhoff) (Coleoptera: Curculionidae) has generated interest to investigate virulence of the entomopathogenic fungus against other crop pests, and how it compares with established commercial biopesticides. In this study, we tested the pathogenicity and virulence of the atoxigenic A. flavus strain to Ootheca mutabilis (Sahlberg) (Coleoptera: Chrysomelidae) in the laboratory compared to the commercial Metarhizium anisopliae (Metschnikoff Sorokin) (Hypocreales: Clavicipitaceae; OD®, ICIPE 69). Serial dilutions of both entomopathogenic fungi (1 × 106–1 × 109 conidia/ml) were evaluated against adult …

Integrated Management Of Aphis Craccivora In Cowpea Using Intercropping And Entomopathogenic Fungi Under Field Conditions, Allan Mweke, Komivi Senyo Akutse, Christian Ulrichs, Komi Kouma Mokpokpo Fiaboe, Nguya Kalemba Maniania, Sunday Ekesi

All Peer-Reviewed Publications

Cowpea aphid, Aphis craccivora, is a major cowpea pest. Cowpea–cereal intercrop alone does not effectively manage the pest. Use of pesticides in intercrop leads to health and environmental risks. Fungal-based biopesticides offer a better option because they are environment-and consumer-friendly. This study assessed the combined effect of Metarhizium anisopliae ICIPE 62 and cowpea–maize intercrop against A. craccivora under six treatments: (1) untreated cowpea monocrop, (2) untreated cowpea–maize intercrop, (3) cowpea monocrop + ICIPE 62, (4) cowpea–maize intercrop + ICIPE 62, (5) cowpea monocrop + Duduthrin insecticide, and (6) cowpea–maize intercrop + Duduthrin during three seasons (long rainy/cold and dry/short rainy). …

Exploiting Insect-Specific Viruses As A Novel Strategy To Control Vector-Borne Disease, Edward I. Patterson, Jandouwe Villinger, Joseph N. Muthoni, Lucien Dobel-Ober, Grant L. Hughes

All Peer-Reviewed Publications

Novel insect-specific viruses (ISVs) are being discovered in many important vectors due to advances in sequencing technology and a growing awareness of the virome. Several in vitro and in vivo studies indicate that ISVs are capable of modulating pathogenic arboviruses. In addition, there is growing evidence that both vertical and horizonal transmission strategies maintain ISVs in vector populations. As such there is potential to exploit ISVs for stand-alone vector control strategies and deploying them in synergy with other symbiont control approaches such as Wolbachia-mediated control. However, before the applied potential can be realized, a greater understanding of their basic biology …

Comparative Analysis Of Viruses In Four Bee Species Collected From Agricultural, Urban, And Natural Landscapes, Tugce Olgun, Sydney Everhart, Troy D. Anderson, Judy Wu-Smart

Department of Entomology: Faculty Publications

Managed honey bees (Apis mellifera L.) and wild bees provide critical ecological services that shape and sustain natural, agricultural, and urban landscapes. In recent years, declines in bee populations have highlighted the importance of the pollination services they provide and the need for more research into the reasons for global bee losses. Several stressors cause declining populations of managed and wild bee species such as habitat degradation, pesticide exposure, and pathogens. Viruses, which have been implicated as a key stressor, are able to infect a wide range of species and can be transmitted both intra- and inter-specifically from infected …
