摘要
采用人工合成的性信息素橡胶诱芯和船形诱捕器对马尾松毛虫成虫进行林间诱捕和幼虫虫口密度监测试验,结果表明:幼虫低虫口密度、成虫低诱捕量时(幼虫虫口密度100条/株以下,成虫诱捕量在65只以下),成虫诱捕量与幼虫虫口密度有较明显的相关性,可以用模拟的幂函数1n(T)=2.278×1n(p)-2.521进行监测预报;幼虫高密度、成虫高诱捕量情况下,成虫诱捕量与幼虫虫口密度相关性不明显。
The test on trapping adult Dendrolimus punctatus by synthetic sex pheromone lure and monitoring of larval population density in forest was conducted.The result showed that,with low population density of larva（below 100 per plant） and low trapping number of adult（below 65）,the trapping number of adult had significantly correlation with the population density of larva,which could be simulated by power function equation 1n（T）=2.278×1n（p）-2.521.With high population density of larva and high trapping number of adult,the trapping number of adult had no obvious correlation with the population density of larva.
