| Abstract: | Enoplognatha japonica is commonly found in cotton fields, rice fields and other fields in Hubei Province with rather stable population density. With good augmentation, the species can be used as a natural enemy of various cotton pests.It has four overlapping generations per year.Duration of the first, second, third and fourth generation was 75, 49, 45, and 66 days, respectively.Female spider needs to mate only once to produce fertilized eggs in its life. The egg mass is well protected in a silk cocoon. One female could produce up to 11 such cocoons. The number of eggs per cocoon was from 134 to 277. It is estimated that one female can oviposit at most 1260 eggs with a hatching rate of about 70%. |
