Olfactory Cues in Host Finding by Melittobia digitata (Hymenoptera: Eulophidae)
Chemical signals used by parasitoids to Þnd hosts often originate from the host, its habitat, or both, providing critical cues for locating hosts that are often cryptic or highly dispersed. MelittobiaWestwood are gregarious ectoparasitoids, which primarily attack Trypoxylon politum Say prepupae.HowMelittobia locates its host is unknown, but itmay involve host-related chemical signals. Therefore...
متن کاملMethods for rearing Syngaster lepidus and Jarra phoracantha (Hymenoptera: Braconidae), larval parasitoids of the phloem-colonizing longhorned beetles Phoracantha semipunctata and P. recurva (Coleoptera: Cerambycidae).
Two species of cerambycid beetles that attack eucalypts, Phoracantha semipunctata (Fabricius) and P. recurva Newman, have been accidentally introduced from Australia into most regions of the world in which their hosts have been planted. The beetles cause extensive mortality in plantations and landscape plantings of the trees. Management programmes have focused on integration of silvicultural pr...
متن کاملPatterns of Host Utilization by Two Parasitoids (Hymenoptera: Braconidae) of the Eucalyptus Longhorned Borer (Coleoptera: Cerambycidae)
t a s p c w e e s e P a u a p p l t b We studied the behavior and biology of the Australian parasitoids Syngaster lepidus Brullé and Callibracon limbatus (Brullé) (Hymenoptera: Braconidae), which are being introduced into California as biological control agents of the eucalyptus longhorned borer, Phoracantha semipunctata F. (Coleoptera: Cerambycidae). Studies conducted in Australia revealed tha...
متن کاملThe effect of host size on the sex ratio of Syngaster lepidus, a parasitoid of Eucalyptus longhorned borers (Phoracantha spp.)
The solitary larval ectoparasitoid, Syngaster lepidus Brull e, parasitizes the cryptic larvae of two wood-boring beetles, Phoracantha recurva Newman and Phoracantha semipunctata F. The objective of this study was to determine how the female parasitoids allocated the sex of progeny when presented with larval hosts of uniform size classes. Host size was directly correlated with age of the Phoraca...
متن کاملPreliminary taxonomic study of the genus Praon (Hymenoptera: Braconidae: Aphidiinae) and its host associations in Iran
در این تحقیق، اطلاعاتی در زمینه‌ی فعالیت زمانی، پراکنش و روابط میزبانی زنبورهای پارازیتویید جنس Praon در ایران ارایه می‌گردد. هشت گونه از این جنس در نواحی مورد بررسی جمع‌آوری شد که از میان آنها چهار گونه‌ی Praon absinthi Bignell،Praon barbatum Mackauer، Praon exsoletum (Nees)و Praon volucre (Haliday) قبلاً از ایران گزارش شده بودند و چهار گونه‌ی دیگر شامل Praon rosaecola Starý، Praon abjectum (Ha...
