日本産カマバチ類の生態に関する比較研究(9) : トビイロカマバチの発育

1. When H. apicalis was reared under conditions at 20, 24, 28 and 32℃, the duration of development from egg to pupa was 44.6days at 20℃ and 16.3days at 32℃ and those at other temperatures were within this range. The durations at 28℃ and 32℃ were similar between them and about 1/2 of that at 20℃. A delay of the development due to a high temperature was suggested at 32℃. H. apicalis parasitizing the 3rd-instar larva of S.furcifera emerged as a final-instar larva from the 5th-instar larva or the adult of the host.
2. Developmental zero and the effective accumulative temperature in the stage from the egg to the adult emergence of H. apicalis was 137℃ and 296.0 degree days, respectively.
3. When H. apicalis parasitized on S.furcifera, the duration of development from egg to pupa at 24℃ was 32.4days, almost the same as on L.striatellus(30.4days). H. apicalis also laid eggs in the nymphs of N.lugens, but these eggs did not grow further.
