Acetylcholinesterase Inhibition in Organophosphate-Resistant Rhyzopertha dominica (F.) (Coleoptera: Bostrichidae)
RESUMO Populações de Rhyzopertha dominica (F.) resistente e susceptível a inseticidas fosforados foram investigadas para verificar a ocorrência de acetilcolinesterase alterada. Malaoxon, a diferentes concentrações, foi utilizado como inibidor em ensaios colorimétricos "in vitro". Populações resistentes provenientes dos municípios de Patrocínio (Minas Gerais, Brasil) e Riley (Kansas, E.U.A.) apr...

(Coleoptera: Bostrichidae), a serious pest of stored cereal grains, is widely distributed and has been collected in different habitats in North America, such as those from agricultural and nonagricultural settings. Our objective was to study the dispersal distances and direction of dispersal by R. dominica after external marking using fluorescen...
متن کاملEvaluation of Physical Losses of Three Wheat Varieties Caused by Rhyzopertha Dominica (f.) (coleoptera: Bostrichidae)
Rhyzopertha dominica (F) is primary pest of stored cereals especially wheat under tropical conditions. The extent of physical damages caused by R. dominica to three common Pakistani wheat varieties was studied. The varieties involved were Sehar -2006, Inqalab-91 and Shafaq.

متن کاملHull characteristics as related to susceptibility of different varieties of rough rice to Rhyzopertha dominica (F.) (Coleoptera: Bostrichidae)
Rhyzopertha dominica (F.), an important pest of stored grains, causes economic damage to rough rice through physical damage to the kernel, resulting in reductions in grain quality. In this test, 28 varieties of commercial rough rice (10 long grain, 11 medium grain, and 7 short grain) were examined for solid, split and cracked hulls, hull thickness, and adult emergence from neonate R. dominica i...
