Biological Characteristics of Trogoderma variabile and the Larva Density on the Effect Pupation

To identify the biology characteristics and the relationship between larva density and popation of Trogoderma variabile,indoor feed and systematic observation were carried out.The result shows that(1)pupate period were(3.97 ±0.91),(4.07±0.88),(5.13±0.89),(9.41±1.49) d,and(18.8±4.3) d respectively,the egg preparing period of imago were(2.14±0.69),(2.25±0.59),(2.43±0.92),(4.53±2.34) d,and(17.23±5.65) d respectively,and the egg period were(5.59±0.49),(5.9±0.97),(8.85±1.04),(13.79±1.0),(28.6±0.26) respectively,under temperature of 35℃,32.8℃,27.8℃,22.8℃,and 17.8℃ relative humidity of(75±3)%.Average emergence rate of pupa was(98.7±0.4)%,average eggs lay by per female was(53.6±5.8),average hatching rate of eggs was(82.8±3.7)%;(2)Life of adult which were fed with honey prolonged,life of females that did not mated was longer than that of males.Howver after pairing the situation was opposite;(3) The more the density of insect was,the longer the pupation of larvae was.(4) The proportion of male and female was 1.0 to 1.1.
