Abstract

Eocantheocna concinna (Walker) is recorded as an important predator of lepidopteran pests in tea plantations of South India. It is described for the first time based on male and female genitalia. Biology of this predator was studied on Corcyra cephalonica larvae. Egg incubation period was 14.3 ± 0.4 days. Five nymphal instars were developed in a period of 33–36 days. Feeding efficacy of different instars of E. concinna was evaluated on third instar tea looper, Biston suppressaria. Results showed fourth and fifth instars of E. concinna attacked faster on B. suppressaria. The study describes E. concinna as a potential predator of various lepidopteran pests in tea plantations and a promising candidate for biological control of looper pests.
