By investigation on the relationship between period, quantity, extend of ostrinia furnacalis emergence and meteorological factors in qiqihaer, this paper analyzes the factors which effect on period, quantity, extend of ostrinia furnacalis about annual wave. the beginning time of ostrinia furnacalis pupae emergence depends on average temperature in may and june, weather conditions in july decide whether ostrinia furnacalis pupae finish ahead of time ; the beginning time of eclosion is decided by average lowest temperature and precipitation in may and june, and the end time of eclosion is decided by average lowest temperature in june and july, meantime, the length of time of ostrinia furnacalis eclosion and time of grub emergence influence on the extent of ostrinia furnacalis. an important condition of a great emergence of ostrinia furnacalis is that how temperature matchs humidity, which substantially result in reduction of maize output
本研究項目通過對齊齊哈爾市玉米螟發生期、發生量、發生程度與氣象條件關系的分析,找出玉米螟發生期、發生量、發生程度年際波動的影響因子: 5 、 6月的平均氣溫決定了玉米螟
化蛹開始的早晚, 7月的天氣條件決定玉米螟
化蛹是否提前結束; 5 、 6月的平均最低氣溫和降水則決定羽
化開始的早晚, 6 、 7月的平均最低氣溫又決定了玉米螟羽
化結束的早晚;而玉米螟羽
化持續時間的長短和幼蟲發生的早晚影響了玉米螟的發生程度;溫濕條件配合適當與否是促使玉米螟大發生的重要條件,玉米螟大發生又會引起玉米的大幅度減產。
In addition, the application of cuticular hydrocarbon analysis to the taxonomic differentiation of the pupae and empty exuviae of six necrophagous flies, were investigated

Egg chambers with the 1st grade appeared on the 11th day after parasitization ( the pupa was white, and its eyes were scarlet ), egg chambers with the 2nd grade appeared on the 12th day after parasitization ad egg chambers with the 3rd grade occurred on the 1st day after emergence. feeding adults of this parasitoid with 20 % honey solution showed no marked effects on the ovarian development except significantly prolonging their life span ( most adults can survive for half a month and even to about a month ). in contrast, feeding with nothing or only wa ter, the wasps only survived for four days. no difference in ovariole lengh of female adults was found among different feedig treatments
卵巢管從寄生后第10天開始出現(此時,卵巢管是透明的,卵室尚未形成) , 1級卵從寄生后第11天開始出現, 2級卵從寄生后第12天開始出現, 3級卵從羽
化后第一天開始出現;喂20蜂蜜水對卵巢發育有一定促進作用,能顯著延長麗蠅
蛹集金小蜂的壽命,不餵食或僅喂蒸餾水,其壽命僅4天,而餵食20蜂蜜水,從第11天開始出現死亡,大部分可存活15天,另有少部分生存達一個月之久。
