Evaluation of Experimental Populations and Glandular-Haired Varieties of Alfalfa for Alfalfa Blotch Leafminer (Diptera: Agromyzidae) Feeding Injury [PDF]

open access: yes, 2018
Following the spread of the alfalfa blotch leafminer, Agromyza frontella (Rondani) (Diptera: Agromyzidae), into Minnesota and Wisconsin U.S.A. during 1994-1997, three field trials were conducted in Minnesota to assess the potential for leafminer ...

Gene‐specific double‐stranded RNAs induce mortality in the South African mealybug Delottococcus aberiae

open access: yesPest Management Science, EarlyView.
Gene‐specific double‐stranded RNAs effectively silence essential genes in the invasive citrus pest Delottococcus aberiae, leading to significant mortality through both microinjection and oral delivery. These results provide proof of concept for RNA interference‐based biopesticides as selective and sustainable tools for citrus integrated pest management.

A Note on the Nesting of \u3ci\u3eMimesa Lutaria\u3c/i\u3e (Hymenoptera: Sphecidae) [PDF]

open access: yes, 2017
Five nests of Mimesa lutaria (Fabricius) were excavated and studied at Cranberry Lake, S1. Lawrence County, NY. The nests were shallower than those of other species previously studied, yet the tumuli were large and conspicuous.
