A New Genus Of Predatory Midge In The Monohelea Complex From Eocene Baltic Amber (Diptera: Ceratopogonidae), Ryszard Szadziewski, William L. Grogan Jr., Elżbieta Sontag, Błażej Bojarski

Insecta Mundi

Monogedania, a new fossil monotypic genus of predatory midge (Diptera: Ceratopogonidae) is described from Eocene Baltic amber and its position within the Monohelea complex is discussed. We dis­covered that the membranous portion of the aedeagus is extended in Monogedania clunipes (Loew), new combination, which suggests that the aedeagus of some extinct predatory midges can be penis-like. The Eocene Monohelea baltica Szadziewski, is transferred to the genus Schizohelea Kieffer, new combination, and, the previously unknown female is described, and key characters are included in color photographs of its entire habitus, head, distal hind tarsomeres and claws.

Factors Contributing To Bee Decline, Ann Mull, Jaydee Gunnell, Sheriden M. Hansen, Ricardo Ramirez, Andree' Walker Bravo, Cody Zesiger, Lori R. Spears

All Current Publications

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 ...

A Versatile Contribution Of Both Aminopeptidases N And Abc Transporters To Bt Cry1ac Toxicity In The Diamondback Moth, Dan Sun, Liuhong Zhu, Le Guo, Shaoli Wang, Qingjun Wu, Neil Crickmore, Xuguo Zhou, Alejandra Bravo, Mario Soberón, Zhaojiang Guo, Youjun Zhang

Entomology Faculty Publications

BACKGROUND: Biopesticides and transgenic crops based on Bacillus thuringiensis (Bt) toxins are extensively used to control insect pests, but the rapid evolution of insect resistance seriously threatens their effectiveness. Bt resistance is often polygenic and complex. Mutations that confer resistance occur in midgut proteins that act as cell surface receptors for the toxin, and it is thought they facilitate its assembly as a membrane-damaging pore. However, the mechanistic details of the action of Bt toxins remain controversial.

RESULTS: We have examined the contribution of two paralogous ABC transporters and two aminopeptidases N to Bt Cry1Ac toxicity in the diamondback moth ...

Entomology Faculty Publications

The benefits of biopesticides and transgenic crops based on the insecticidal Cry-toxins from Bacillus thuringiensis (Bt) are considerably threatened by insect resistance evolution, thus, deciphering the molecular mechanisms underlying insect resistance to Bt products is of great significance to their sustainable utilization. Previously, we have demonstrated that the down-regulation of PxmALP in a strain of Plutella xylostella (L.) highly resistant to the Bt Cry1Ac toxin was due to a hormone-activated MAPK signaling pathway and contributed to the resistance phenotype. However, the underlying transcriptional regulatory mechanism remains enigmatic. Here, we report that the PxGATAd transcription factor (TF) is responsible for the ...
