of the genus Megastigmus Dalman, 1820 (Hymenoptera: Torymidae) native and introduced to the west Palaearctic region: taxonomy, host specificity and distribution.
Available electronically on the Internet by the end of 1995, the updated version of Chalcid Corner will have a voice component that warns users to "be careful," if they are making an error in their search.
The program allows users to choose from a list of alternative questions about chalcids, then proceed through a series of screens to help identify a wasp.
females, when unable to reach the host with their ovipositors, dug as deep as 5 cm into wheat flour to find host pupae.

wasp of the genus Astymachus Howard from Vietnam (Hymenoptera, Chalcidoidea: Encyrtidae).
In the fruit fly specialist Coptera haywardi (Ogloblin) (Diapriidae), nearly all ovipositions are in the middle regions of Anastrepha suspensa (Loew) puparia, while the generalist chalcid
, Dihrinus himalayanus Westwood, frequently oviposits in both the middle and the posterior (Sivinski et al.

parasites of phytomyzids.

, but not bees (reviewed in Bino et al.
Some of the thousands of different species of these wasps, one to two millimeters in length, found around orchards include: Braconid wasps (family Braconidae); Ichneumonid wasps (family Ichneumonidae); Chalcidoid wasps (family Chalcidoidea); Chalcid wasps (family Chalcididae); Eulophid wasps (family Eulophidae); Trichogramma wasps (family Trichogrammatidae); Mymarid wasps (family Mymaridae).
There are two main groups of parasitoid mini-wasps: ichneumonids, which lay their eggs mainly in the larvae (caterpillars) and pupae (cocoons) of moths and butterflies; and chalcids
, which lay their eggs not only in larvae and pupae, but in eggs, nymphs and adults of virtually every type of insect.
Different from the situation in other chalcids
, we found that the BCPS were only distributed on the distal part of the segments of the funicle and the clava of EGW females, while they were distributed in the ventral side and lateral surface of segments of the funicle and clava except for the first funicular segment of the EGW male.
