I investigated mechanisms of parasitoid coexistence in a spatially structured host–multiparasitoid community (harlequin bugs [Murgantia histrionica] and two specialist parasitoids [Trissolcus murgantiae and Ooencyrtus johnsonii ]). I tested both local and metapopulation hypotheses. The local hypothesis, intraguild predation, predicts coexistence if the inferior larval competitor is superior at ...

Eight species of parasitic wasps were bred from various stages of five species of hesperiids viz. Thoressa evershedi (Evans), Pelopidas mathias (Fabricius), Udaspes folus (Cramer), Borbo cinnara (Wallace) and Caltoris sp. inhabiting Western Ghats, Kerala, India. One new species, Dolichogenidea kunhi Gupta & Kalesh, is described and illustrated from Kerala, India, and its relationship with close...

In the Atlas cedar forests located on northern massifs of Blidean and at eastern extension Saharan Atlas, 79 egg batches processionary moth Thaumetopoea pityocampa (Denis & Schiffermuller, 1775) were collected during summer period from two sites: Chrea National park (46), Ouled Yagoub forest (33). To assess effect characteristics parasitism, eggs monitored after hatching larvae and/or emerg...

The insect egg parasitoid is a potential agent of biological control for pest, especially concerning the development technology alternative pest control. existing species parasitoids in rice agroecosystems needs known their use as an effective and efficient. research aimed to determine diversity, dominance, parasitization levels based on plant growth. location sampling were done Matangkuli Syam...

Leptoglossus occidentalis Heidemann (Heteroptera: Coreidae), commonly known as western conifer seed bug (WCSB), is an invasive pest in the Mediterranean, where it has been associated with decline of Pinus pinea L. kernel production. A biological control WCSB populations native egg parasitoids may reduce economic losses. With purpose to obtaining masses laid situ bags WCSB, adults were placed, f...
