1. The percentage of diapause under field conditions. The peach fruit borer, Carposina niponensis Walsingham, has a complete firstgeneration and a partial second generation annually in Liaoning province, the majorapple-growing district in China. It passes the winter as full-grown larva encased in athick, elliptical cocoon under ground. A record of two years'(1956--1957) observation in Hsiung-yao (40°10′N) on theoccurrence of diapause is shown in table 1. The data show that the later the larvaeemerged from the fruits, the greater the proportion of the larvae entering diapause.Larvae that emerged before July 21 never entered diapause; of those that emerged fromJuly 26 to August 16 not over 20 per cent had gone into diapause; those that emergedfrom August 16 to August 20 had a diapause rate increasing sharply up to 80 per cent;and those that emerged in end of August all entered diapause. 2. Effect of the length of daily photoperiod on the induction of diapause. The influence of the photoperiod on the induction of diapause is dominant at me-dium temperatures. Almost 100 per cent of the larvae grown at medium temperatures(25°and 27℃.), with 13 hours illumination per day, entered diapause; but only a smallproportion of the larvae grown at the same temperature, with 15 hours illumination perday, entered diapause (usually not over 10 per cent). Table 2 shows that most of the larvae grown under complete darkness entered dia-pause. The only exception to this is the result concerning larvae of the first generationat 27℃. The same table shows that as the photoperiod increased from 15 hours up to 17 and24 hours per day, the percentage of the larvae entering diapause increased accordingly. From the results shown in table 2, it is apparent that the critical photoperiod liesbetween 13 and 15 hours of illumination per day. 3. The effect of temperature on diapause. For the larvae grown in complete darkness, the effect of temperature in inducingdiapause is shown in table 3. Experimental data show that when the larvae were heldat 15°, 18°, 21°, 23° and 25℃., almost 100 per cent of them entered diapause; whenthe temperature was over 25℃., the proportion entering diapause decreased sharply; andunder 34℃., the percentage of diapause dropped to 9 per cent. On the other hand,when the larvae were held at 12℃., about one third of them would not enter diapause.Experimental data again show that the effect of the duration of illumination per day on the induction of diapause of the larvae which were held at low temperatures (18°to 22℃.) were practically the same as at medium temperatures (25° and 27℃.). 4. The relationship between the length of photoperiod and diapause undernatural conditions. According to an analysis of the relationship between the change of day length whichoccurred in the larval growth season of the first-generation and the proportion of larvaeentering diapause at different dates, it is concluded that under natural conditions, thelength of day plays a dominant role in determining which individuals of the full fedlarvae will enter diapause. The average atmospheric temperature was 23℃. at thattime (Table 5); and it seemed to have no effect on the induction of diapause. Thecritical photoperiod for the induction of diapause in natural conditions will be 14:50 to14:13 hours of light per day (Table 6). Figure 3 shows the change of day length (hours) and date of critical photoperiodin the first-generation larval growth season at Hsiung-yao. Owing to the fact that theincidence of diapause in the first-generation was markedly influenced by the timing ofthe light-sensitive larval stage in relation to the critical date, figure 3 also illustratesa comparison between the first-generation oviposition periods of three different years.In the year 1956, nearly all the first-generation eggs were deposited before the criticalphotoperiod date, probably only a small proportion of the first-generation larvae enteringdiapause. Accordingly, a greater number of the second-generation eggs were laid whencompared with the first-generation (1:

桃小食心虫在辽南苹果产区为二化性兼性滞育害虫。据在熊岳的观察,第一代幼虫通常于7月下旬开始脱果,凡脱果日期愈晚的幼虫,进入滞育的百分率愈高。在中间温度下,滞育的发生决定于幼虫发育期间昼夜光照时数:在每日光照13小时下发育时,全部滞育,在15小时下发育的,基本不滞育。根据田间第一代幼虫发育期间温度和日照时数的变化与幼虫滞育百分率进度的关系推算结果,第一代幼虫发生期间的温度是在光周期反应的适温范围内,故温度不是引起滞育的主要因素。推算出来的临界光周期位于14小时50分—14小时13分之间(在熊岳出现该光周期的日期为7月21号左右)。最后,讨论了田间第一代幼虫发生期早晚与滞育百分率及第二代发生量的关系:在春季干旱的年份(如1955、1957),由于第一代幼虫发生期被推迟,滞育百分率提高,从而减少了当年第二代的发生量;相反,在第一代幼虫发生期较正常年份提前的1956年,该代的滞育百分率降低,从而相应增加了第二代的发生量。

The entomopathogenic nematode,Taishan No. 1, Heterorhabditis sp.(Heterohabditidae) was isolated from the overwintering larvae of the peach fruit-borer, Carposina niponensis walsingham and from the soil of apple orchards in Shandong province in May 1984. The life cycle of this nematode was found containing two generations, they were oviparous generation(short generation) and ovoviviparous generation(lon ggeneration). This parasitic nematode associated with the bacteria Xenorhabdus sp.,which were released after the parasites entering the body cavity of the insects. The insect hosts were then be killed within 48 hours by septicaemia. The dead insects did appear red colour and bioluminescent,caused by the symbiotic bacteria. The Taishan No.1 nematode can be developed in artificial media. The mortalities of the overwintering larvae of the peach fruit-borer infested by the Taishan No. 1 nematode were much higher than by Neoaplectana feltiae. In the present paper, the life cycle, morphology, symbiotic bacteria development in artificial media and the infestation of the overwintering larvae under the laboratory conditions of this species were investigated.

昆虫病原线虫泰山Ⅰ号是小杆目异杆线虫科异杆线虫属(Heterorhabditis)线虫。1984年5月,自山东泰安苹果园土壤及桃小食心虫(简称桃小)(Carposina niponensis Walsingham)圆茧分离获得。在长江以北地区分离到这种昆虫寄生性线虫还未见有报道。其生活史包括两个世代,即卵生世代(短世代)和卵胎生世代。25℃温度下完成整个生活史需9天时间。它与一种无色杆菌(Xencrhabdus)互惠共生,线虫进入昆虫体腔便释放出其共生菌,引起昆虫败血病,48小时内导致寄主死亡。尸体变红并发出较强的生物光。本文主要报道其生活史、形态、共生菌、人工繁殖方法及对桃小的致死效果。
