Influence of temperature on the functional response of Anisopteromalus calandrae (Hymenoptera: Pteromalidae), a parasitoid of Rhyzopertha dominica (Coleoptera: Bostrichidae)
The functional response of Anisopteromalus calandrae (Howard) parasitizing 4th-instar Rhyzopertha dominica (F.) on wheat was estimated over a range of temperatures and host densities. A functional response equation was used in which a quadratic component that included temperature was substituted for handling time. The instantaneous search rate increased with increasing temperatures. The maximum...
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 کاملAcetylcholinesterase 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 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...
