Effect of male and female adult age on the mating success and male EAG response to sex pheromones of the legume pod borer, Maruca vitrata;

Studies on the behavioral biology of first and second generation adults of the Asian corn borer(Ostriniafurnacalis (Guenee))II the emergence and mating acthritles and oriposition rhythm;

Studies on the behavioral biology of first and second generation adults of the Asian corn borer(Ostrinia furnacalis (Guenee))I the resting and mating locations and the behavioral dynamics in the nighttime;

The emergence mainly occurred from 18:00 to 2:00 in next day and copulation mainly occurred from 21:00 to 24:00;CONCLUSION The peak of copulation was at 23:00 or so.

The time of emergence of both sexes and copulation frequency and time of dif- ferent individuals were distinct.

The results showed that the adults mated during 20:00-01:00,and the mating peak arrived between 22:00-23:00.

Evidence for a female sex pheromone in the mating behavior of Coscinesthes salicis adult.;

The results were as following:8204 female parent prawns, 5683 male parent prawns and 5360 coupled prawns were obtained in the two years, the mating rate was 71.

In order to raise the mating rate of Penaeus orientalis, an experiment was made on prolonging the mating season with a plastic big shed in 1993, 1994.
