白蜡窄吉丁Agrilus planipennis Fairmaire是近年来发生和危害严重的国际性检疫害虫。为了了解不同饲养条件和种内个体间相互感知对成虫生物学的影响,本研究采用群体饲养、单对饲养、无隔离单雌饲养、视觉隔离单雌饲养和嗅觉隔离单雌饲养等5种处理,在室内测定了白蜡窄吉丁成虫的寿命、取食量、产卵量和产卵历期等参数的变化。结果显示:隔离饲养降低了白蜡窄吉丁成虫的寿命和繁殖力,且不同处理下白蜡窄吉丁成虫的寿命和取食量均存在显著差异(P<0.05),但产卵量的差异不明显(P>0.05)。其中无隔离单雌饲养时成虫的平均寿命最长,为32.40d,群体饲养的寿命最短,为20.77d,且单雌饲养的寿命均比单对饲养和群体饲养的长。单雌饲养的3种情况下,视觉隔离条件下的日均取食量最大,为156.16mm2,嗅觉隔离的最小,为107.35mm2;无隔离饲养条件下雌虫的产卵量最大,产卵历期也最长,分别为98.33d和21.33d。这些研究结果表明,白蜡窄吉丁种内个体间相互感知的阻断对成虫的取食、发育和繁殖活动存在明显影响,且嗅觉在其种群内的交流活动中作用最重要,其次是视觉。此外,个体之间的相互干扰或竞争对白蜡窄吉丁成虫的寿命和繁殖力也可能存在一定的影响。这为生产上采用隔离措施如营造混交林带防治该虫提供了理论基础。
The white naringenin Agrilus planipennis Fairmaire is an international quarantine pest that has occurred in recent years and is seriously endangered. In order to understand the effects of different feeding conditions and the mutual perception among individuals on the biology of adult beetles, five treatments (group feeding, single feeding, single feeding without isolation, single feeding with visual isolation and single feeding with olfactory isolation) The changes of life span, food intake, egg production and ovipositing duration were determined indoors. The results showed that the isolation and feeding reduced the lifespan and the fecundity of the adult C. parahaemolyticus, and there were significant differences in the life span and the feeding amount of the A. baicalensis adults under different treatments (P <0.05), but the differences in the number of eggs were not significant Obviously (P> 0.05). Among them, the average longevity of adults without isolation of single female was the longest, which was 32.40d. The shortest longevity of group feeding was 20.77d, and the longevity of single female was longer than that of single pair and group. Under the condition of single female feeding, the average daily food intake under the condition of visual isolation was 156.16mm2, the minimum of olfactory isolation was 107.35mm2; The longest period, respectively, 98.33d and 21.33d. These findings suggest that blockade of individuals in C. constella has significant effects on feeding, development and reproduction of adults, and that olfaction plays the most important role in communication within its population, followed by vision. In addition, mutual interference or competition among individuals may also have some effect on the lifespan and fertility of C. jejuni adults. This provides a theoretical basis for the production of isolation measures such as the construction of mixed forest belt to control the worm.
