摘要
为开展黑龙江省马铃薯甲虫的监测与防控,在两个疫情发生县市的网室内开展了越冬成虫发育、卵孵化、幼虫生长发育、老熟幼虫入土羽化、一代羽化成虫生理发育过程调查。结果表明:通过调查,得到了马铃薯甲虫在黑龙江省的发生规律,确定马铃薯甲虫在黑龙江省一年发生2代,以成虫在寄主田越冬,越冬成虫一般在第二年6月中旬出土,4~7 d后交尾产卵,卵孵化期5~6 d,后卵孵化为一代幼虫取食为害,13~15 d后老熟幼虫入土羽化,土层深度5~10 cm。蛹期10~12 d羽化为一代成虫。一代成虫发育10~12 d后,交尾产卵,孵化为二代幼虫,为害7~10 d后入土化蛹,蛹期10~12 d,羽化为二代成虫,二代成虫入土越冬。
In order to carry out the monitoring and control of potato beetles in Heilongjiang Province,the physiological development process of overwintering adults,egg hatching,larvae growth and development,the eclosion of mature larvae and the first generation adults was investigated in the net room of the two counties where the outbreak occurred.The results showed that:through investigation,we obtained the occurrence regularity of potato beetles in Heilongjiang Province,determined that potato beetles occur in Heilongjiang Province 2 generations in a year.The adultts wintered in the host field,overwintering adults generally appear in mid-June the next year,overwintering adults mating and lay eggs after 4 to 7 days,egg incubation period was 5-6 d,the first generation of larvae after hatched feed on potato,after 13 to 15 days,the mature larvae entered the soil and emerged,soil layer depth was 5 to 10 cm.It takes 10 to 12 days for pupae to emerge into adults.The first generation of adults lay eggs after development of 10 to 12 days,hatching into the second generation of larvae is harmful,the old larva pupae goes into the soil after 7 to 10 days,pupal stage is about 10 to 12 days,eclosion into the second generations of adults,they go into the soil forover wintering.
