摘要:  【目的】证实并探明柑橘大实蝇Bactrocera minax成虫在中国板栗Castanea mollissima雄花花序上的取食行为,从而为柑橘大实蝇的非化学防控提供理论依据。【方法】采用录像技术对柑橘大实蝇成虫在中国板栗雄花花序上的行为活动过程进行跟踪观察和分析。【结果】柑橘大实蝇成虫在中国板栗雄花花序上的取食行为分为爬行、取食、梳理和静息4个阶段,成虫的取食行为没有固定次序,除无法从静息阶段直接到取食阶段外,成虫可从爬行、取食、梳理和静息4个阶段中的任一阶段随意转入另一阶段。成虫取食行为各个阶段的频次占比由高到低排列顺序为:爬行>取食>梳理>静息。静息阶段平均耗时显著超过取食、梳理和爬行阶段;取食、梳理和爬行阶段之间的平均耗时无显著差异。柑橘大实蝇雌成虫与雄成虫之间,各个阶段频次占比和平均耗时均无显著差异。【结论】结果证实柑橘大实蝇雌雄成虫在中国板栗雄花花序上存在取食行为。

Abstract: 【Aim】 This study aims to confirm and elucidate the feeding behaviour of adult Bactrocera minax on male inflorescence of Castanea mollissima in the wild, so as to provide references for prevention and control of this insect using non-chemical control methods in China. 【Methods】 The feeding behavior of adult B. minax on male inflorescence of C. mollissima was tracked with video technology and analyzed. 【Results】 The results showed that the feeding behaviour of adult B. minax was characterized by four phases, i. e., walking, feeding, grooming and inactivity, and the sequence of these four phases was not fixed. Except being unable to go from the inactivity phase to the feeding phase, adult B. minax could optionally transit from one phase to another among the four phases. The proportion of frequency of each behavior of adult B. minax in the order from high to low was as follows: walking>feeding>grooming>inactivity. The average time of the inactivity phase was significantly longer than that of the feeding, grooming and walking phase, and the difference in the average time was not obvious among the feeding, grooming and walking phases. There was no significant difference in the proportion of frequency and average time of each phase between females and males. 【Conclusion】 These results confirm the presence of feeding behavior of adult B. minax on male inflorescence of C. mollissima.
