Life history,immature morphology and adult behavior ofTelenomus solitus [Hymenoptera: Scelionidae]

The results of laboratory studies on the life history, morphology of immature stages, effects of food and water on adult longevity, host age preference for oviposition, parthenogenesis, and adult behavior ofTelenomus solitus Johnson are presented.Telenomus solitus completed its development in 10.8 days (egg, 0.3 day; 1^st instar, 2.7 days; 2^nd instar, 3.7 days; and pupa, 4.1 days). The adults lived longest when provided with both honey and water. Without food, they survived less than 24 h. Parasitization of host eggs varied significantly with their age, being highest in 42 h old eggs. Fewer than 10% of eggs older than 60 h were parasitized successfully. The periodicity of oviposition was unimodal; it occurred throughout the 24 h period and peaked in the late photophase. Females ofT. solitus are arrhenotokous. The behavioral sequences during courtship, mating, and oviposition are described.
