Behavior and life cycle of Epilachna vigintioctopunctata (Fabricius) (Coleoptera, Coccinellidae) in Lycopersicum esculentum Mill. (Solanaceae).

Abstract

Epilachna vigintioctopunctata is a pest of many plants of agricultural importance in Asia. In 1990, the species was found in Brazil, near Curitiba, State of Paraná, in cucurbitaceous plants. In February 2002, specimens were collected in Solanum americanum in Itajaí, State of Santa Catarina. The adults were kept under ±24°C, >53% RH, at 12 h photoperiod, and fed with leaves of Lycopersicum esculentum [Lycopersicon esculentum]. The average was 24.45 eggs per oviposition and the incubation period was 7.14 days. The viability of the eggs was 63.68%. The average of 1st, 2nd, 3rd and 4th larval instars was 5.88, 4.62, 5.88 and 9.81 days, respectively. The average of the larval development was 26.19 days and the pupal development was 8.19 days. The average of life cycle was 41.44 days, and of the period of preoviposition, oviposition and postoviposition was 23.57, 17.86 and 53.86 days, respectively. The fecundity of the females was 59.78 eggs. The average of longevity of male and female was 81.44 and 97.89 days, respectively.
