Fitness of a Malathion-Resistant Strain of the Parasitoid Anisopteromalus calandrae (Hymenoptera: Pteromalidae)
Biological Þtness of a malathion-resistant (R) and a malathion-susceptible (S) strain of the solitary parasitoid Anisopteromalus calandrae (Howard) was compared when the wasps were parasitizing immature rice weevils, Sitophilus oryzae (L.), in stored wheat. Despite having a .2,500-fold naturally occurring resistance, in the absence of insecticide the R strain was equal to the S strain in abilit...
متن کاملInfluence 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 کاملVenom gland components of the ectoparasitoid wasp, Anisopteromalus calandrae.
The wasp Anisopteromalus calandrae is a small ectoparasitoid that attacks stored product pest beetle larvae that develop inside grain kernels, and is thus a potential insect control tool. The components of A. calandrae venom have not been studied, but venom from other organisms contains proteins with potential applications, such as pest management tools and treatments for human diseases. We dis...
متن کاملSTORED-PRODUCT AND QUARANTINE ENTOMOLOGY Selection of Cold Injury Treatments to Facilitate Release of the Parasitoid Anisopteromalus calandrae (Hymenoptera: Pteromalidae) Reared on the Rice Weevil (Coleoptera: Curculionidae)
The use of cold treatments to kill the rice weevil, Sitophilus oryzae (L.), before eclosionbut allow theparasitoidAnisopteromalus calandrae (Howard) tocompletedevelopment and eclosion was examined. Cold tolerance, crystallization temperature, and developmental stage of rice weevilswere examined at 2-d intervals between 18 and 30d after riceweevil oviposition. Themedian crystallization temperatu...
متن کاملBIOLOGICAL CONTROL Effects of Protect-It on Efficacy of Anisopteromalus calandrae (Hymenoptera: Pteromalidae) Parasitizing Rice Weevils (Coleoptera: Curculionidae) in Wheat
The parasitoid Anisopteromalus calandrae (Howard) was very sensitive to direct contact with Protect-It, an inert dust formulation containing 90% diatomaceous earth and 10% silica aerogel. LT50s at room temperature and humidity were 49 min (95% CL 5 48Ð51) and 72 min (95% CL 5 69Ð74) for males and females, respectively, in petri dishes containing 2.5 mg dust per square centimeter. Under the same...
