Application Effect of Insect Sex Pheromone in Xinyang Tea Garden
摘要
Abstract
In order to study the effect of insect sex pheromone in tea gardens,an experiment was carried out in Zhenleishan tea garden using tussock moth and geometrid sex pheromone. The re sults showed that,when population density of tussock moth and geometrid at a low level,there was a positive correlation between trap catches and population. The trap catches could accurately reflect dynamic changes of insect population. The first generation adults of geometrid were used as an example. The trap catches of geometrid sex pheromone was more than that of black lamp. The daily maximum trap catches of the former was 35, but that of the latter was only 3 in the same day. When the population density of the overwintering and second generation of tussock moth was low,the trap catches could also accurately reflect dynamic changes of insect population. But if the population density was at a high level,the predictive index of sex pheromone was lower than that of black lamp. For example, when the first generation adults of tussock moth seriously increased, the highest trap catches of sex pheromone was 155, but that of the black lamp was 298,so trap catches of black lamp could accurately reflect the increasing trend of insect population. As the forecast and prevention tool,the sex pheromone had better effect than black light lamp when population density of tea tussock moth and geometrid was at a low level,and the control effects of sex pheromone on geometrid and tussock moth were 73. 36% and 90. 28%, respectively. When tea tussock moth broke out, the control effect of sex pheromone was not obvious. The combination with other non-pollution prevention means was needed.关键词
