摘要
在室内研究了不同饲养代数对番石榴实蝇各虫态发育历期的影响。结果表明：室内继代饲养番石榴实蝇,第1代和第15代卵历期、1～3龄幼虫历期、蛹的历期间无明显差异（卵历期：F=1.04,P〉0.05;1龄幼虫历期：F=0.65,P〉0.05;2龄幼虫历期：F=0.83,P〉0.05;3龄幼虫历期：F=0.58,P〉0.05;蛹历期：F=0.36,P〉0.05）。继代饲养到第15代时,番石榴实蝇成虫交配前期增加（F=5.15,P〈0.01）,成虫第1次交配到第1次产卵时间间隔也表现为随着继代饲养代数的增加而逐渐增加（F=2.12,P〈0.05）,产卵前期时间逐渐增加（F=2.88,P〈0.01）。由此可见,室内继代饲养番石榴实蝇,其发育历期随继代饲养代数的增加而延长。
Study on the effect of successive rearing on the development duration of Bactrocera correcta was conducted in laboratory. The results showed that the development duration of B. correcta increased with the increase of successive rearing generations. There was no significant difference for the eggs,the larvae duration from the 1^st to the 3^rd instars and the pupa duration of B. correcta from 1^st to 15^th generations（ egg stage： F = 1. 04,P〉0. 05; larvae stage： 1stinstars： F = 0. 65,P〉0. 05; 2^nd instars： F = 0. 83,P〉0. 05;3^rd instars： F = 0. 58,P〈0. 05; pupa duration： F = 0. 36,P〈0. 05）. The premating duration（ F =5. 15,P〈0. 01）,the time interval of the first mating to the first oviposition（ F = 2. 12,P〈0. 05） and the pre-oviposition period（ F = 2. 88,P〈0. 01） of B. correcta increased gradually with the increase of successive rearing generations,after 15 generations of successive rearing. All the results showed that the population of guava fruit flies would decrease with the increase of the rearing generations in the laboratory.
