Postteneral Protein Feeding may Improve Biological Control Efficiency of Aphytis lingnanensis and Aphytis melinus
The augmentative releases of mass-reared Aphytis spp. (Hymenoptera: Aphelinidae) parasitoids are widely used against armored scales. The nutritional status and the initial egg load of Aphytis spp. females are key to their success as biological control agents. For these reasons, this work focuses on the study of providing a protein feed to Aphytis lingnanensis (Compere) and A. melinus DeBach to ...
متن کاملMale-Male Sexual Behavior in the Parasitic Wasp Psyttalia concolor
The role of male-male courtship in parasitic Hymenoptera is poorly known. A laboratory study was conducted to assess if Psyttalia concolor (Szépligeti) (Hymenoptera: Braconidae) male courtship can be affected by a previous experience in courting young conspecifics of both sexes. Two experiments were performed to evaluate the effect of experience in courting young wasps on both male courtship an...

متن کاملDispersal of Aphytis melinus (Hymenoptera: Aphelinidae) after augmentative releases in citrus orchards
The efficacy of natural enemies in controlling pests under field conditions is largely correlated with their capacity to spread within infested crops. In this study the spatial dispersal of the California red scale parasitoid Aphytis melinus DeBach (Hymenoptera: Aphelinidae) was evaluated in the field after augmentative releases. The experiment was conducted in 2007 in six 1-ha plots in a Sicil...
متن کاملRecords and descriptions of some Aphelinidae (Hymenoptera: Chalcidoidea) from India
Two new species, Centrodora flemingiae Hayat, sp. nov. and Proaphelinoides assamensis Hayat, sp. nov. (Hymenoptera: Aphelinidae), are described.
