我国不同地区棉褐带卷蛾的性行为观察

观察结果表明，茶小卷蛾性行为反应与成虫的虫龄关系甚为密切；当天羽化的雌雄蛾已具有一定程度的交尾能力。如和交尾能力更强的1，2天虫龄的异性配对时，性行为反应的比率达到实验最高值；我国不同地区棉褐带卷蛾24小时内性行为反应基本类似，雄虫振翅和交尾率均在凌晨6：00-7：00达到了高峰。茶小卷蛾和棉小卷蛾交叉配对时，交尾率达53.33%和60．00％。但当苹小卷蛾和茶小卷娥配对时．则未见任何交尾活动。我国不同地区棉褐带卷蛾显示出很强的同源性；本讨论了我国北方棉褐带卷蛾(苹小卷蛾)与南方棉褐带卷蛾（棉小卷蛾、茶小卷蛾)．目前可视为两个不同的亚种。

OBSERVATION OF THE SEX BEHAVIOR RESPONSES BY ADOXOPHYES ORANAMOTHS IN DIFFERENT PARTS OF CHINA

The sex behavior responses of the smaller tea tortrix was closely related to theadult age. The result of experiments showed that the newly emerged moths maintained aconsiderable mating ablity,When they were provided with the one or two-day- oldheterosexual with stronger mating ablity,there occurred a peak of responses rate in sexualbehavior.The sex behavior responses by Adoxophyes orana moths in different parts of China all peaked from 6 :00 to 7:00a. m .during twenty-our hours of a day, The similarities ofsexual responses by A doxophges orana in different parts of China indicated that all of themwere homologous. When the smaller tea tortrix moths were proviede with the smaller cotton tortrix, thereoccured 53. 33%or 60. 00%mating behavior. While provided with the smaller apple tortrix,no mating behavior occurred.It was therefore considered that A doxophyes orana fromnorthern China(called smaller apple tortrix ) was a subspecies totally different from thosefrom southern China(called smaller tea tortrix or smaller cotton tortrix).
