Investigations carried out on the parasite-hyperparasite complex of the coconut pest Opisina arenosella Walker indicate that the hyperparasites considerably reduce the population of the parasites and thus lower the efficiency of the latter as biological control agents. Over half the cocoons of the parasitoid Apanteles taragamae Vier., were parasitised by the hyperparasites, with Aphanogmus mani...

Abstract We evaluated the diversity and spatiotemporal emergence patterns of parasitoid wasp species in genus Eurytoma Illiger (Hymenoptera: Eurytomidae) associated with leaf galls induced by Diplolepis variabilis Bassett Cynipidae) throughout Okanagan Valley, British Columbia, Canada. collected D. region, recorded adult times, extracted mitochondria DNA from a subset emergents, used cytochrome...

The guild of stem-infesting insect pests of sunflower, Helianthus annuus L., within the central Plains is a concern to producers chiefly due to losses caused by plant lodging from the sunflower stem weevil, Cylindrocopturus adspersus (LeConte) (Coleoptera: Curculionidae), and Dectes texanus texanus LeConte (Coleoptera: Cerambycidae). The incidence of a root boring moth, Pelochrista womonana (Ke...

Nearly 3,500 specimens of microgastrine wasps (Hymenoptera: Braconidae) were reared during caterpillar surveys undertaken in 2010-2013 across India, covering 16 States and one Union Territory (Andaman & Nicobar islands), and deposited in the National Bureau of Agriculturally Important Insects, Bangalore, India. The caterpillar inventory recovered over two hundred morpho-species within 22 famili...
