Biological attributes of Hadronotus pubescens (Motschoulsky) (Hymenoptera: Scelionidae) reared on refrigerated eggs of Riptortus pedestris Fabricius (Hemiptera: Alydidae).

ABSTRACT: Hadronotus pubescens (Motschoulsky) (Hymenoptera, Scelionidae) is a solitary egg parasitoid that lays its eggs in the eggs of Riptortus pedestris Fabricius (Hemiptera: Alydidae), which is a major pest for legume crops in Korea, Japan, and Bangladesh. This study assessed the quality of refrigerated R. pedestris eggs in relation to host-accepting behaviors and biological characteristics, including parasitism rate, development duration, emergence rate, sex ratio, and longevity. The hatchability of the refrigerated eggs was evaluated. R. pedestris eggs that were refrigerated for over 30 days failed to hatch entirely. The refrigeration influences the average duration of each host acceptance behavior (i.e., drumming, drilling, oviposition, and marking) on host eggs. The number of parasitized hos
