The larvae of Chrysopa sinica could complete their development on an encapsulated diet of hydrolyzed protein of brewer′s yeast,soybean,and beef,although duration of larval stage was lengthened and pupal weight

用啤酒酵母、大豆、牛肉水解物为主的饲料,制成蜡壳人工卵饲养中华草蛉(Chrysopa sinica)幼虫可以完成发育,但与用米蛾卵饲养的处理比较,幼虫历期延长,茧重减轻;对蛹历期、成茧率、羽化率、性比、产卵前期均无显著影响。将饲料制成人工卵的饲养结果比用泡沫塑料吸附法显著为好。部分龄期喂人工卵的比全幼虫期喂人工卵的影响为轻,一、二龄喂米蛾卵,三龄喂人工卵的处理,虽然对蛹重仍有影响,但在幼虫发育历期和成虫获得率上与全幼虫期喂米蛾卵的差异不显著。全幼虫期或部分龄期喂人工卵和全幼虫期喂米蛾卵饲养出来的草蛉成虫用啤酒酵母干粉作成虫饲料,30天内的产卵量差异不显著。据生防室以前的试验,三龄幼虫取食的米蛾卵量占全幼虫期总取食量的76%,因此一、二龄喂米蛾卵,三龄喂人工卵既不影响草蛉的繁殖力,又可节省大量米蛾卵,在生产实践上有应用价值。

All the rearing procedures for L. grisescens had to maintain these two reproductive colonies. The corn borer larvae were reared in 27 cm plastic boxes in diameter containing artificial diet 750 g and a density of 500-800 larvae per box (fig.1).At 28-30℃and 70-90% RH on a 14- to 10-hour light-to darkness-schedule, the first...

This paper reports the techniques and methods of mass rearing of the larvi-parous tachinid fly Lydella grisescens using its natural host, the corn borer Ostrinia furnacalis during 1983-1984. All the rearing procedures for L. grisescens had to maintain these two reproductive colonies. The corn borer larvae were reared in 27 cm plastic boxes in diameter containing artificial diet 750 g and a density of 500-800 larvae per box (fig.1).At 28-30℃and 70-90% RH on a 14- to 10-hour light-to darkness-schedule, the first instar larvae could develop to the older instar larvae within 21 days without adding or replacing their diet (fig. 2). The adult flies were held in gauze cages for emergence and mating till maggots extraction. Food ( 5 % honey solution and milk) and water were supplied to the flies for 3-4 times daily. At 28-30℃ and 70-80% RH, and under the conditions of sunlight and gentle breeze, male flies having emerged one day before could readily male with the newly emerging female flies. Percentage of mating was about 80-90%.Inseminated female flies were reared at 25-30℃ and 80-90% RH with a photoperiod of 12 hr light and 12 hr dark,the eggs in uterus completed their development in 9 to 11 days. There were 100-245 maggots in the body of each female adult. After a small amount of physiological saline was dripped into the culture dish with 10-15 cm in diameter, well-developed maggots were taken out of the uteri of the female flies (fig. 6 ) and then the maggots enclosed from egg-shells moved away in all directions (fig. 7). 3-4 maggots were applied for one host larva in average within the culture dish (fig. 8 ) , which was covered by a round lid of the wet screen, and after two hours inoculated corn borer larvae were taken out from the dish. After 4 to 5 days black triangular spots were obviously observed near the spiracles of the body of parasitized corn borer larvae called "maggot's respiratory infundibulum" (fig. 9, 10). This respiratory infundibulum was an important characteristic to distinguish parasitized host larvae from unparasitized ones. Percentage of corn borer larvae parasitized after inoculating maggots was about 80-90%.The results of our experiment showed that various host larval stages and different maggots/host larva densities are major factors influencing the parasiti-zation by L. grisescens. The 5th stage host larva was selected as more suitable host for L. grisescens to parasitize, and the optimum density was 3 - 4 maggots/host larva.

本文报道1983—1984年我国利用自然寄主亚洲玉米螟(Ostrinia furnacalis)幼虫人工大星繁殖玉米螟厉寄蝇(Lydella grisescens)的技术和方法。研究结果表明:在正常的玉米螟人工饲料配方中添加0.05克维生素E后,饲养和累代繁殖的供试玉米螟幼虫对提高寄蝇的生活和生殖力效果显著;温湿度、光照和风是影响寄蝇交尾的三因素,温度28~30℃,相对湿度70—80%,日光光照和微风吹拂为寄蝇交尾的适宜条件;掌握羽化1天以上的雄蝇与当天羽化的雌蝇这一有利时机,交尾率可达80—90%;受精雌蝇以5%稀蜂蜜液和牛奶喂饲后,寿命延长,胚胎发育良好;在温度25—30℃及相对湿度80—90%的条件下,子宫内的卵经9—11天全部成熟,采用人工剖腹取蛆,以蛆与寄主幼虫的密度比为3:1或4:1,使其充分接触的接蝇蛆方法,寄生率一般为80—90%,最高可达98%;根据同一寄主幼虫体内寄生1—4个蝇蛆的不同营养和发育情况,测定其蛹重,观察和比较成虫抱卵量、寿命和生殖力的强弱,证明1头玉米螟幼虫体内寄生1—2厉蝇蛆较为有利。 玉米螟厉寄蝇人工大量繁殖研究的成功,不仅有利于我国玉米螟防治工作,而且将为我国生防...
