We use an integrative taxonomic approach to revise the genus Anisopteromalus. In particular, we apply multivariate ratio analysis (MRA), a rather new statistical method based on principal component analysis (PCA) and linear discriminant analysis (LDA), to numerous body measurements and combine the data with those from our molecular analysis of Cytb and ITS2 genetic markers (on a subset of speci...
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...
در بررسی که در سال 1389 در شرق استان گلستان به منظور بررسی زنبورهای پارازیتویید آفات انباری و پراکندگی میزبانیشان انجام شد، در مجموع 7 گونه زنبور پارازیتویید متعلق به 5 خانواده روی 10 نوع محصول غذایی انبارشده به شرح ذیل جمع آوری و شناسایی شدند: Anisopteromalus calandrae (Howard, 1881) (Pteromalidae) Anisopteromalus mollis Ruschka, 1912 (Pteromalidae) Cephalonomia tarsalis (Ashmead, 1893) (...

Ecological theory suggests that frequency-dependent predation, in which more common prey types are disproportionately favored, promotes the coexistence of competing prey species. However, many of the earlier empirical studies that investigated the effect of frequency-dependent predation were short-term and ignored predator-prey dynamics and system persistence. Therefore, we used long-term obser...
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...
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...

(Coleoptera: Curcuionidae), parasitized by Anisopteromalus calandrae Howard) (Hymenoptera: Pteromalidae) could be sepaated from uninfested kernels and kernels that conained unparasitized weevils by using near-infrared NIR) spectroscopy. Wheat kernels from cultu...
