摘要
根据濮阳市气象条件的变化对棉铃虫特别是对棉铃虫虫源影响的特点,按照棉铃虫繁育规律,将棉铃虫周年活动期划分为秋季预蛹期、越冬期、春季羽化期、夏季危害期4个阶段;分阶段选取有昆虫学、统计学意义的气象因子,通过归一化处理和加权组合,组成棉铃虫气象指数,建立多时效、归一化棉铃虫气象预报模式和分析、评价指标。
This article mainly deals with Puyang mcteorological changes and their effects on cotton boll worms, especialy on the worm source. According to the worm breeding law, the yearly cycle is divided into four stages autumn pupa period, overwintering period, spring eclosion period and summer damaging period. On different stages, meteorological factors are selected in insectology and statistics, which are normalized and weighted combination to make up the worm meteorological index, to establish the worm meteorological forecasting pattern and analyzing ＆ evaluating index over long periods of effectiveness.
