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...
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. There was recorded significant production of frass material and weight loss in all tested varieties after pest infestation...
متن کاملTemperature-mediated functional response of Theocolax elegans (Hymenoptera: Pteromalidae) parasitizing Rhyzopertha dominica (Coleoptera: Bostrichidae) in stored wheat
The functional response of Theocolax elegans (Westwood) parasitizing the lesser grain borer, Rhyzopertha dominica (F.) was examined over a range of temperatures. A type II functional response equation was fitted to each temperature regime. The parasitization rate was highest at 301C (20 hosts per day) and was lowest at 201C (2 hosts per day). Handling time was inversely proportional to temperat...
متن کاملWalking stability of Rhyzopertha dominica (Fabricius, 1792) (Coleoptera: Bostrichidae).
Results obtained in studies can contribute to the advancement of science and innovative methods and techniques for developing practical activities. Reporting conditions that may restrict the implementation of research is critical to ensure the optimal development of further technical studies. The objective of this study was to assess the walking stability of R. dominica on a flat and smooth sur...
متن کاملDispersal of Rhyzopertha dominica (Coleoptera: Bostrichidae) in different habitats.
The lesser grain borer, Rhyzopertha dominica (F.) (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...
