Oviposition behaviour of mated or unmated Cleruchoides noackae (Hymenoptera: Mymaridae)

Experiments were conducted to observe mating and oviposition behabiour as well as biology of hog-plum beetle. Results revealed that the average mating frequency, mating duration and mating interval were 11.2, 30.5 hours and 60.3 hours, respectively. The highest number of eggs per clusters was on leaf rachis followed by young stem. The mean number of eggs per cluster was 15.70 while the length and breadth of an egg was 1.95 mm and 0.60 mm, respectively. The mean duration of 1st, 2nd, 3rd and 4th instar larvae were 3.80, 3.40, 3.70 and 3.00 days, respectively. The mean pupal period was 22.74 days. The female beetle lived longer (48.30 days) than the male (45.10 days). The size of female beetle was larger (15.30 mm) than male (11.96 mm). The mean length of antennae was 7.42 mm. The length of fore, mid and hind legs were 9.20, 9.50 and 11.70 mm, respectively. Hind wings were larger (16.10 mm length and 7.85 mm breadth) than fore wings (12.38 mm length and 5.30 mm breadth).Bangladesh J. Agril. Res. 42(3): 503-508, September 2017

The life-history of Pseudorhyssa sternata Merrill was investigated under natural and artificial conditions.When P. sternata and Rhyssa persuasoria (L.) females were present on Siricidinfested logs, P. sternata observed the primary parasite making drill shafts, and after the primary withdrew its ovipositor and moved away, P. sternata located the shaft and inserted its ovipositor to gain access to the host. P. sternata was able to locate R. persuasoria drill shafts aged 1–38 days.P. sternata females were stimulated to oviposition behaviour when presented with paper drilled by R. persuasoria, and this response was enhanced by the presence of wet Siricid frass, or the symbiotic fungus of Siricids. Ovipositor probing was also made through artificial holes into frass. Bioassay of R. persuasoria vaginal and venom glands resulted in considerable probing into filter paper impregnated with vaginal gland extract.It was concluded that P. sternata females probably locate Siricid-infested trees by responding to a generalised stimulus that is potent in larval frass, and which possibly derives from the symbiotic fungus. The cleptoparasite probably finds the drill-shaft by responding to a secretion of the vaginal gland of the primary parasite.
