应用性信息素对河北地区枣树皮暗斑螟进行了林间监测。结果表明,性信息素能够准确监测皮暗斑螟成虫发生动态,精确测报其发生量。2年的监测结果说明,全年蛾主要发生期自4月中旬至8月下旬,有世代交替现象。成虫越冬代羽化相对集中,主要在4月底5月初,其余时间羽化量没有明显的高峰。雄蛾对人工合成性信息素的昼夜反应基本发生在深夜,其反应模式为单峰式——夜间型,敏感时期为午夜0:00—3:00。通过诱捕虫量对虫株率和虫口密度做回归分析,得出性信息素测报皮暗斑螟危害及发生状况,其测报公式为:y诱捕虫量=0.0181x有虫株率;y诱捕虫量=1.0242x虫口密度。
Application of pheromone on the jujube bark borer in Hebei forest monitoring. The results showed that the sex pheromone can accurately monitor the occurrence of Porphyridium cruentum adults and accurately measure its occurrence. 2 years of monitoring results show that the main annual moth occurrence period from mid-April to late August, there are generations of alternating phenomena. The overwintering adults were relatively concentrated during the winter, mainly at the end of April and early May. There was no obvious peak of emergence in the rest of the season. Male and female pheromones synthesized artificial pheromone diurnal night-time reaction occurred in the middle of the night, the reaction mode is unimodal - nocturnal type, sensitive period of 0: 00-3: 00 midnight. Through the regression analysis of insect trapping rate and insect population density, the results of sex pheromone measurement of Haematophagoides punctiferalis and its occurrence were as follows: y trapping insect quantity = 0.0181x insect strain rate; y trapping insect Amount = 1.0242x insect population density.
