橘小实蝇卵引诱其雌虫聚集和产卵研究
Bactrocera dorsalis Females Attracted to Their Eggs for Further Oviposition
摘要
Abstract
Bactrocera dorsalis Hendel females have the habit of gathering together to lay eggs.To elucidate the aggregation and oviposition behavior of the fruit fly,this study investigated the role of B.dorsalis eggs in attracting the females to gather and lay eggs,and explored the effects of the attraction on B.dorsalis females of different ages and mating status and the differences between eggs and host fruits in attracting the females to gather and lay eggs.The results showed that B.dorsalis females were significantly more attracted to their eggs(36.0％)than to the control(12.0％)within 2 h;in contrast,males were attracted significantly less to their eggs(0.67％)within 2 h than to the control.The attraction of the females differed between laboratory and wild B.dorsalis populations,being the highest of47.67％at 0.4 g eggs for the laboratory population and 13.67％at 1.2 g eggs for the wild population.We detected an effect of egg amount on the induction of oviposition,0.8 g eggs induced the largest oviposition(762.0 eggs)in the laboratory population and 1.0 g eggs induced the largest oviposition(790.8 eggs)in the Anshun population.When tested against females of different ages,the eggs induced the laboratory population to deposit 2945.0 eggs on 15 days and the Anshun population to deposit 2530.5 eggs on 12 days.The eggs laid by mated females in the laboratory populations,genetic strains,Anshun populations,and Fuzhou populations were significantly more than that by unmated females.In choice and no-choice tests,eggs induced B.dorsalis oviposition of 624.33 and 844.00 eggs,respectively,which were significantly higher than those induced by fruits of Psidium guajava,Averrhoa carambola and Citrus sinensis.These results indicate that B.dorsalis eggs can attract the B.dorsalis females to gather and induce oviposition,and the oviposition induction is higher than that of the host fruit.关键词
