The Biology Of Apanteles Galleriae Wilkinson (Hymenoptera: Braconidae) And Its Control Effects On The Two Wax Moths

In this thesis, the biology peculiarity of Galleria mellonella Linne and Achroia grisella Fabr were studied, and how to differentiate the two wax moths were summarized under amalgamating condition. Meanwhile, the biology of Apanteles galleriae Wilkinson , thermal threshold and thermal sum for the development, the parasitize to various instar larvae and various host larvae and functional response to different temperature regimes were investigated. The main results were as follows:The suitability of G. mellonella to environment is stronger and at 25-35℃,the temperature is higher, the period of oviposition of female adults is longer, the average period is 9.93d.The peak oviposition occurred in the 2^nd day after laying eggs, later the number of oviposition is decreased gradually. The suitability of A. grisella weaker than the G. mellonella, and it didn't accomplish development at 35℃. At 30℃, the oviposition number of female adults is the most (average 282.85). The peak oviposition occurred in the 2^nd day after laying eggs.A. galleriae has five generations within a year in the laboratory of HuNan. A. galleriae emerged in the day-time, and the peak emergence occurred in 8-12h. 63.3% male wasps emerged in 0-10h, 65.5% female wasps emerged in 8-14h. The number of emergence was the most and 94.7% wasp in 1-4^th day. The most oviposition number by one female wasp was 68,and the average of oviposition number by one female wasp was 45.4. The oviposition position by female wasp at the 1-4^th abdomen of host mostly, and only one or two eggs were laid. The parasitoid larva come out at the 1-3^rd abdomen of host.Developmental temperature of A gallehae one generation was 25-30℃, and which didn't complete developing at 35℃.At 25℃ and 30℃,the mean development periods of one generation was 21.41d and 16.88d respectively. Maximum mean longevity was 35.6 days for wasps, fed on 30% honey solution at 22℃. The developmental zero and accumulated temperature of one generation were respectively 11.79℃ and 338.5 day-degrees; the developmental zero of larva was higher than egg and pupae.In all day, the parasitism for A. gallehae occurred in the daytime of 14-22h was higher than that of 8-14h. A. gallehae could parasitize 1-4^th instar of G. mellonella larvae, but preferred 2^nd and 3^rd instar when the 2^nd, 3^rd and 4^th instar of host larvae were exposed simultaneously to this parasite, and the preference indexes were 0.35 and 0.42 respectively. The development velocity of A. gallehae parasitizing in the 4^th instar larva was faster than development of those parasitizing in the 3^rd and the 2^nd instar larvae, and the body length of the wasps was bigger than parasitoid parasitizing in 2^nd instar larva...
