Laboratory rearing of Abidama liuensis (Hemiptera: Cercopidae) and description of immature stages

Abstract

Because it is an important pest of rice, Abidama liuensis Metcalf is well documented in terms of its bioecology and control. However, there are few studies on the biology of this pest. In this study, a technique was developed for rearing this insect under laboratory conditions (26 ± 2°C; 75 ± 3% RH; and 12L : 12D photoperiod) and its immature stages are described. Egg development is divided into four stages, of which S1 took the longest time (accounting for 11.70% of total developmental time); 90% of the eggs that completed S2, hatched. Nymphal instars can be distinguished by body size, colour and other morphological features. Total developmental period of immature stages was approximately 50 d, with the averages of the five stadia 5.18, 4.33, 5.28, 10.41 and 8.5 days, respectively. Using this rearing technique, it is possible to rear A. liuensis throughout the year, which will facilitate further ecological, behavioural and molecular studies and the development of ways of controlling this insect in the field.
