An investigation on association of seed borer, Trymalitis margarias Meyrick infestation with ecological parameters was carried out in sapota between 2016 to 2019. Seed borer incidence commenced from September (1.00–1200%) and the peak activity was reported during December (8.50 to 9.25%) at initial fruiting phase. The fruit damage slightly decline in January and again attained maximum in March (10.75%) and April (10.50%) at advance fruiting stage and negligible in July and August. The linear coefficient correlation data revealed that seed borer caused higher damage due to raise of bright sunshine hrs and evaporation as well as by lesser of minimum temperature, morning-evening relative humidity along with absence of rainfall and rainy days equally under preceding and current circumstances. The fruit damage persuades with higher number days comprising <15 °C temperature, <50% relative humidity and > 6 h bright sunshine light along with lesser number days having >80% relative humidity. The regression equations showed variability between 72 to 93% under eight weather parameters with significant impact of minimum temperature, morning and evening relative humidity, evaporation and rainfall on alternate years and had impact on seed borer succession. There was no major deviation in observed and predicted incidence except at early and ending fruiting phase.

天气因素对螟螟Trymalitis margarias Meyrick发生的影响及可靠性

2016 年至 2019 年期间，在 sapota 开展了一项关于螟虫、Trymalitis margarias Meyrick 侵染与生态参数的关联性调查。螟虫发病率从 9 月开始（1.00-1200%），12 月报告了活动高峰（8.50% 至 9.25%） ) 在最初的结果期。果实损伤在1月份略有下降，3月份（10.75%）和4月份（10.50%）在提前果期再次达到最大值，7、8月份可以忽略不计。线性系数相关数据表明，在以前和现在的情况下，由于明日照时间和蒸发量的增加，以及最低温度、早晚相对湿度较小以及没有降雨和阴雨天的情况，螟虫造成的危害更大。果实受损的天数较高，包括 <15 °C 的温度、<50% 的相对湿度和 > 6 小时的明亮阳光，以及具有 >80% 相对湿度的较少天数。回归方程显示，在 8 个天气参数下，变异性在 72% 至 93% 之间，最低温度、早晚相对湿度、蒸发量和降雨对隔年产生显着影响，并对螟虫演替产生影响。除了早期和结实期外，观察到的和预测的发生率没有重大偏差。回归方程显示，在 8 个天气参数下，变异性在 72% 至 93% 之间，最低温度、早晚相对湿度、蒸发量和降雨对隔年产生显着影响，并对螟虫演替产生影响。除了早期和结实期外，观察到的和预测的发生率没有重大偏差。回归方程显示，在 8 个天气参数下，变异性在 72% 至 93% 之间，最低温度、早晚相对湿度、蒸发量和降雨对隔年产生显着影响，并对螟虫演替产生影响。除了早期和结实期外，观察到的和预测的发生率没有重大偏差。
