粘虫

High altitude region is more srious than low region. The armyworm imperilment degree varies in different crops. The field planted wheat as forcrop is serious. Also, different levels of cultivation management have evident effects on the imperilment degree of armyworms. For instance, the fields of rough management and bad crop growing suffered more serious imperilment than those of high quality management, intensive cultivation and good crop growing way.

Pseudelatia separata (Lepidoptera: Noctuidae) infected with Pseudelatia separata NPV and Pseudelatia separata GV and coinfected with the two viruses, the structural characters of its prothoracic gland and the ultrastructure of the gland cells were observed. The results showed that pathological changes appeared in the infected PTGs.

In a meeting held at Harbin 1959, discussing the possible over-winter sites of theOriental armyworm, Leucania separata Walker, in the Northeast, a hypothesis was pro-posed (Chang, 1959) that this insect most probably did not over-winter in the Northeast,but the outbreak every spring was due to mass migration of the adult moths along withthe south or southwest trade winds.

根据东北地区的粘虫极大可能不在本地越冬而是每年春季随南、西南风大量迁飞的假设，利用气象资料分析了东北早春粘虫成虫的发生与风向风速的关系。无论由始现期或突增期来看，与地面上或高空850 mb的南、西南风均有较高的符合率；在粘虫出现时期的南、西南风多为每秒5—6米到每秒9—10米的大风。

The calling and copulation behaviour of Ancylis sativa Liu had a dielperiodicity.The female moths began to calling at the first day and increasedto 100% at the second day,then the percentage of calling decreasedgradually from the third day to the fifth day,only 16.7% of females showingcalling behaviour at the sixth day.The effect of environmentaltemperature on calling behaviour of Ancylis sativa Liu was studied duringadult life at 16℃,21℃,26℃ and 31℃.The result showed differenttemperature during adult life affected significantly the calling behaviour ofvirgin females.There was considerable variability in the calling patternsamong the different temperature groups,the higher the temperature was,thelater females called,the shorter the calling behaviour lasted.The copulationbehaviour of Ancylis sativa Liu can be divided into following squence:female calling,male responsing,male approaching female,hairpencil displayingand copulating.

枣粘虫求偶和交配行为研究结果表明，在光周期为14L：10D、温度为21℃下，越冬代枣粘虫雌蛾的求偶高峰期为黑暗期6.0-8.0小时，求偶活动以羽化后1-3天表现强烈，第二天求偶百分率高达100％，第4天开始，求偶百分率下降，到第6天仅为16.7％；环境温度对枣粘虫雌蛾的求偶活动有明显的影响，随着温度的下降，求偶高峰期明显提前，求偶高峰期的持续时间变长，在21、26、31℃下，求偶百分率接近或达到100％，在16℃下，仅为43％；枣粘虫的交配行为可分为雌蛾求偶、雄蛾反应、雄蛾接近雌蛾、打开味刷及交配成功等阶段；交配活动也以羽化后前3天表现强烈；第1、2代在黑暗周期中的交配高峰期比越冬代推后1-2.5小时；越冬代枣粘虫的交尾持续时间多为3-4小时，第1、2代比越冬代短；越冬代交尾前期多为2-3天，第1、2代多为1-2天，少数羽化当天便可交尾；雌雄成虫均有多次交尾习性，雄蛾最高交尾6次，平均3.3次，雌蛾最多交尾3次，平均1.5次，在田间自然条件下，大多数越冬代雌雄成虫只交尾1次，第1、2代交尾次数有所增高，第1、2代成虫交配率明显高于越冬代。
