| effect of temperature on efficacy of insecticides to differential grasshopper (orthoptera: acrididae). | the effect of temperature on activity of insecticides for controlling grasshoppers in leafy green vegetables was evaluated. insecticides evaluated had differing modes of action and included diflubenzuron, azadirachtin, beauveria bassiana, spinosad, endosulfan, esfenvalerate, and naled. we evaluated these insecticides for efficacy to third instars of differential grasshopper, melanoplus differentialis (thomas), at temperatures ranging from 10 to 35 degrees c. in the laboratory, treatment with esf ... | 2004 | 15568348 |
| amoebogregarina nigra n. gen., n. comb. (apicomplexa: gregarinidae) from adult melanoplus differentialis (orthoptera: acrididae) in southeastern nebraska. | amoebogregarina nigra n. gen., nov. comb. (eugregarinida: gregarinidae) is described from trophozoites, gamonts, associations, gametocysts, and oocysts collected from adult melanoplus differentialis (orthoptera: acrididae) in nemaha county, nebraska. host alimentary canals were examined for eugregarine parasites. gregarines encountered were fixed as permanent specimens or subjected to a series of morphometric measurements. morphometric analysis indicated the presence of gregarina nigra, a poorly ... | 1999 | 10219316 |
