摘  要:
为了明确吉林省水稻田双斑长跗萤叶甲种群发生动态及温度对其盛发期的影响,2010—2012年对吉林省长春地区、松原地区、梅河口地区的水稻田双斑长跗萤叶甲发生情况进行了系统调查,并分析了双斑长跗萤叶甲发生期内温度的变化。结果表明:双斑长跗萤叶甲成虫于7月上旬在水稻田始见,8月上中旬进入盛发期,9月上旬数量减少。当日平均温度>21℃时,双斑长跗萤叶甲稻田初见,日平均温度>25℃时,成虫种群数量达到盛发期,日平均温度<20℃时,虫量逐渐减少。5月份温度对双斑长跗萤叶甲盛发期影响较大,5月份温度低盛发期延迟。

摘  要:
To determine Monolepta hieroglyphica( Motschulsky) population dynamics and influence of temperature on its outbreak period in rice fields of Jilin province,we systematically investigated and analyzed population quantity of Monolepta hieroglyphica( Motschulsky) in Changchun,Songyuan and Meihekou of Jilin province during 2010—2012. The results showed that Monolepta hieroglyphica( Motschulsky) was found at the beginning of July,and it started to outbreak in early to mid-August,and decreased at the beginning of September. When average daily temperature was above 21 ℃,Monolepta hieroglyphica( Motschulsky) first appeared,reached the peak when average daily temperature was above 25 ℃,and the quantity reduced gradually when average daily temperature was below 20 ℃. Temperature of May had an influence on outbreak period of Monolepta hieroglyhica( Motschulsky) and the peak would delay if temperature was low in May.
