摘要: Antilochus coquebertii is one of the most important predators of Dysdercus koenigii. The present study examines for the first time the fitness (using age-stage and two-sex life table parameters), morphometrics and predating potential of A. coquebertii fed on the second instar of D. koenigii under laboratory conditions. Results indicate that female adults of A. coquebertii consumed significantly higher numbers of second instar D. koenigii (229.81 +/- 14.36) when compared to male adults (118.47 +/- 10.77). The body length (16.10 +/- 0.40 mm) and width (6.60 +/- 0.20 mm) of female adults of A. coquebertii were significantly higher if compared to body length (14.40 +/- 0.40 mm) and width (5.80 +/- 0.40 mm) of male adults. The developmental period of A. coquebertii from egg to female adult (76.09 +/- 3.51 days) was significantly longer than egg to male adult (64.00 +/- 1.87 days). The fecundity (number of eggs/female) of A. coquebertii was 108.67 +/- 3.67 per female. The intrinsic rate of increase (r) and finite rate of increase (lambda) per day of A. coquebertii were recorded with values of 5.87 and 1.06 days, respectively. The gross reproductive rate (GRR) and net reproductive rate (R0) of A. coquebertii were 23.17 offspring and 18.56 offspring/individual, respectively. The information obtained in this study will be useful for the development of future research projects focused on this predator against D. koenigii under natural conditions. Based on our results, we suggest that A. coquebertii will be a good biological control agent against the second instar of D. koenigii in cotton fields.
