酱香型大曲曲虫发生规律研究

Occurrence Rules of Jiangxiang Daqu Pests

采用频振式杀虫灯对酱香型大曲曲虫进行诱捕,结果表明,酱香型大曲曲虫优势种群为土耳其扁谷盗,爆发期为每年7月、8月、9月;老车间曲虫数量高于新车间;曲虫的捕捉量与温度呈正相关,杀虫灯在晴天和多云天气时,曲虫捕捉较多。

Frequency trembler grid lamp was used for trapping Jiangxiang Daqu pests. The results showed that, the dominant Daqu pest popula- tion was Cryptolestes turcicus and its burst period was July, August and September; the number of Daqu pests in old workshops was evidently higher than that in new workshops; the catch amount of Daqu pests was positively correlated with the temperature, and more pests were cap- tured by the lamp in sunny day and cloudy day.
