Description
Dryinid wasps play a dual role of true predators as wellas parasites. Then feeding and oviposition of eight adults females of Haplogonatopus atratus Esaki et Hashimoto were observed for thier entire life span. The experiments were conducted at 24℃ under 16 hours lighting.
When 20 nymps of 3rd instar per adult female were provided for oviposition every day, longevity of adult female was 31.9±3.85 days and total fertility and number of hosts fed upon by adult female were 1152.8 eggs and 194.4 nymphs respectively. Adult male longevity was 3.9±2.36 days. The oviposition behaviour of female occured within 24 hours after adult emergence, and the fertility per day increased rapidly till about 4 days after adult emergence. The average fertility per day was the highest on 7-16 days after adult emergence, then it was reducing gradually till a few days before the death, though value of it was relatively high level. Predation behaviour occured soon after aduit emergence andendedwith death, and number of hosts fedupon by adult female did not show extream fluctuation during the life with a constant level in change. There was positive correlation between longevity of adult female and number of hosts fed upon by adult female, and also number of hosts fed upon by adult female and fertility (r = 0.775, 0.903).
