On The Origins Of The Insect Fauna Of California's Channel Islands: A Comparative Phylogeographic Study Of Island Beetles, Michael S. Caterino, Stylianos Chatzimanolis, Maxi Polihronakis Richmond

Publications

California’s 8 Channel Islands host a large diversity of insects, the vast majority of which are shared with mainland southern California. The existence of a small number of recognized endemic species, however, suggest that, for some lineages, the islands are isolated enough to have permitted significant differentiation. Here we investigate the phylogeographic relationships of 4 beetle species (Thinopinus pictus, Hadrotes crassus, Hypocaccus lucidulus, and Nyctoporis carinata): all occurring on the mainland and on multiple (up to 6) Channel Islands. Sequences of the cytochrome oxidase I mitochondrial gene (and, for one species, an intron in the …

Parental Rna Interference Of Genes Involved In Embryonic Development Of The Western Corn Rootworm, Diabrotica Virgifera Virgifera Leconte, Chitvan Khajuria, Ana María Vélez, Murugesan Rangasamy, Haichuan Wang, Elane Fishilevich, Meghan L.F. Frey, Newton Portilho Carneiro, Premchand Gandra, Kenneth E. Narva, Blair D. Siegfried

Department of Entomology: Faculty Publications

RNA interference (RNAi) is being developed as a potential tool for insect pest management and one of the most likely target pest species for transgenic plants that express double stranded RNA (dsRNA) is the western corn rootworm. Thus far, most genes proposed as targets for RNAi in rootworm cause lethality in the larval stage. In this study, we describe RNAi mediated knockdown of two developmental genes, hunchback (hb) and brahma (brm), in the western corn rootworm delivered via dsRNA fed to adult females. dsRNA feeding caused a significant decrease in hb and brm transcripts in the adult females. Although …

Phenology Of Zagryphus Zulaya Gauld (Hymenoptera: Ichneumonidae: Tryphoninae) In A Montane Forest In Guatemala And A New Country Record For Z. Vegai Gauld, Jack C. Schuster, Gabriella Steele

Insecta Mundi

Ichneumonidae are incredibly diverse, yet there have been few Guatemalan ichneumonid studies. We studied the phenology of 215 specimens of Zagryphus zulaya Gauld (Hymenoptera: Ichneumonidae: Tryphoninae), most captured in a light trap and two Malaise traps in a montane (1850m) forest from 2002 to 2014. One of the Malaise traps caught over 95% of the specimens. The results suggest that Z. zulaya is most abundant in May, June, July, and August, the rainy season. Zagryphus vegai Gauld is newly recorded from Guatemala; it was previously known only from Costa Rica. It was found at an altitude of 1850m, though its …
