The codling moth is widely distributed throughout Sinkiang Uighur Autonomous Region, andis considered to be the most destructive fruit pest to the apple and the pear. In order to combatthis fruit borer effectively, investigations on the biology and chemical control of this insect pesthave been conducted in this region since 1956. The present paper gives only the resultsobtained in Ili, the major apple growing district in this region, in 1957 and 1958. 1. The moths have two full, and a partial third generations a year. However, about 51.5%of the first brood larvae do not pupate but remain in their cocoons until the following spring.The seasonal lifecycle records together with the spraying schedule are presented in this paper. 2. The emergence climaxes of the overwintering and the first generation of the year 1957were in agreement with that of 1958, and were separated by 48 & 54 days for these years respec-tively. The oviposition climaxes of the first and the second generations in the year 1957 and1958 closely resembled each other, and separated by 46 & 49 days. Again, the hatching climaxesof the first and the second broods occurred almost at the same date in the two successive years,with intervals of 45 & 46 days. All these indicated that in completing one full generation, about45--54 days were required. 3. The preoviposition period of the overwintering generation and that of the first generationwere 3.6 & 4.5 days, and 3.4 & 6.1 days for the two years respectively. The maximum numberof the eggs deposited by a single female of different generations in 1957 and 1958 were 84-125-141,while the average number was 32.6-43 eggs. The longevity of the adult of the overwintering andthe first generation averaged 6.8--10.6 days and 7.6-9.1 days respectively. It is found that thelongevity of the adult could be lengthened by a nectar supply. The longevity of the female isalways longer than that of the male. The sex ratio is 1:1. 4. The first appearance of the egg and the total number of eggs deposited on different varietiesare different. Among the 564 eggs of the first generation found in 1957, 21.9% was found on theearly variety, 25.9% on the median variety, and 52.1% on the late variety. By examining thenumber of infested fruits on different varieties. It is also found that the accumulative percentageof the bored fruit differed with different varieties. In 1957, the first brood larvae infesting theearly, median, and the late varieties were 35%, 41.5% and 55% respectively. These facts reveal thatfor forecasting the first appearance of the egg and the number of infested fruits, proper selecting ofdifferent varieties are of importance. 5. The incubation period of the eggs averaged from 8--9 days in general, and from 5--6days in the hot weather. In the year 1957, the overwintering generations began to lay their eggs at the.begining of May, and these eggs hatched in from 10--21 days, with an average of 15 days;whereas in the year 1958, they started to deposit their eggs in late April, and hatched in from 13--24days, with an average of 19.2 days. So, the first brood larvae of both years hatched in late May.It is extremely important to bear this in mind when arranging the schedule of DDT spray. 6. It has been found that the threshold temperature for the development of the codling mothis 9℃ or 10℃, according to different authors and that approximately 230 day-degrees of effectivetemperature are required to bring about the hatching of the earlist larvae of the first generation.According to our observation and calculation, 9℃ is more suitable as a basists to start with 237.3day-degrees were reached on May 25th, 1957, and 232.9 day-degrees were reached on May 22nd,1958, the calculated dates for these two years coincided nicely with what are actually observed inorchards. This indicates that the method of "Thermal Sums" holds fairly well in forecasting thefirst appearance of the first hatching. 7. According to the date the newly hatched larvae bore into, and the mature larvae come outof the infested fruits, the larval period lasted 25.5--30.2

The codling moth,Laspeyrisia pomonella(L.),a fruit borer,is oneof the major pests most harmful to apples and pears in the world.Manycountries,as well as China,have listed it as an object of plant quar-antine.In China today,the infestation of this pest is confined only toXinjiang.The Commonwealth Institute of Entomology(C.I.E.)(1951,1976)based on the reports by Chen Fang-jie and Wang Fei-peng(1936)and C.F.Wu(1938),placed China's Zhejiang(Fenghua),Hebei,Hubei,The Three Northeastern Provinces(Liaoning、Jilin and Heilongjiang),Peiping(now Beijing),and XingJiang all together eight provinces andmunicipalities,on the list of codling moth infested areas,thus causedserious influence on the export and sales abroad of China's apples andpears.In order to make sure the real situation of the pest distributionin China,first,the mistakes in the two reports which the C.I.E.hadbased on for charting were checked and corrected;and,at the sametime,on the basis of the results of the tests conducted by Zhang Cong-zhong et al.(1984-1985),(where codling moth sex pheromone wereused as attractants),over large areas in the above mentioned provincesand municipalities,more intensive tests were carried out during the pe-riod of April to October,1991,in major apple and pear growing regionsand export bases scattered in the provinces of Shandong,Liaoning,andHebei,using again the codling moth sex pheromone as attractants.Factsgleaned from the tests,the orchard investigations and fruit dissection,neither adults nor larvae,have been found.Up to the present,the dis-tribution of codling moth in China is confined solely to Xinjiang.

苹果蠹蛾[Laspeyresia pomonella(L.)]是世界上为害苹果和梨的主要蛀果害虫,被许多国家和我国列为植物检疫对象。该虫在我国现仅分布于新疆。英联邦昆虫研究所(Common-wealth institute of entomology,C.I.E.)(1951,1976)根据陈方洁、王飞鹏(1936)及胡经甫(1938)的记述,将我国浙江(奉化)、河北、湖北、东北三省(辽宁、吉林、黑龙江)、北平(北京)及新疆等8个省、市、自治区划分为该虫分布区,从而严重影响我国苹果及梨的出口和外销。为了查清该虫在我国的分布情况,首先核对并纠正 C.I.E.制图所依据的上述两篇文章的错误,同时在张从仲等(1984—1985)在山东、辽宁等8省市大面积进行的苹果蠹蛾性诱剂监测的基础上,于1991年4—10月在山东、辽宁、河北苹果和梨主要产区及出口基地继续进行苹果蠹蛾性诱剂监测、果园调查及剖果检查,结果均未发现苹果蠹蛾成虫或幼虫。到目前为止,此虫仍局限分布于我国新疆。

The Codling moth, Laspeyrisia pamoneda (L. ) , is one of the most important quarantine pests in the world. In the distribution map of codling moth that Commonwealth Agricultural Bureaux (CAB) lately published in 1976, 1989, Liaoning, Jilin, Hebei, Beijing, Hubei and Zhejiang altogether six provinces of China had been placed on the list of codling moth infested areas and it caused serious influence on the export and inport of China's apples and pears. In order to clarify the real distribution situation of this pest in China, monitoring sites were build to monitor this pest by use of the codling moth sex pheromone as attractants from 1991 to 1993 in Dalian, Yingkou, Jinzhou, Yantai, Qingdao, Qinhuangdao, Shijiazhuang, Xihua and Beijing. During this time, monitoring tests were conducted in different types of apple orchards of 8 monitoring sites from March to October in each year, the total monitored area is 648. 2 ha. From July to October in each year, there were altogether 44 times for the orchard investigation and fruit dissection, it covered 70 counties, 176 different type of orchards, 5058. 9 ha investigation areas, 15163 apple and pear trees, 1978419 apple and pear fruits were carried out in above monitoring sites and the near areas. The results of these monitoring tests and orchard investigation for 3 years in succession showed that neither adults nor larvae of L. pomonella have been found. Besides, we found CAB mistakenly quoted in literatures by checking the reports that CAB had based on for charting the distribution map of this pest. Investigation obviously revealed that codling moth does not exist in the main fruit production area of East China.

苹果蠹蛾[Laspeyresia pomonella(L.)]是世界检疫性害虫。英联邦农业局(CAB)受联合国粮农组织(FAO)的委托,多次公布的该虫世界分布图上,一再将我国东部(尤其渤海湾沿岸)划为该虫分布区,从而严重影响我国苹果、梨的出口;同时,一些有该虫分布的国家也据此要求我国放宽对苹果进口的检疫规定,构成了对我国苹果、梨生产的严重威胁。为查清该虫在我国的分布实况,作者在1991年监测调查的基础上,于1992—1993年,在辽、鲁、冀、京、豫五省市进行了多点重复监测调查。3年来,各基点于4—10月进行该虫性诱剂诱集监测,监测面积累计达648.2ha,代表不同地区不同类型果园;于7—10月进行果园调查及剖果检查,共计44次,调查了77县(区)的176个果园,累计调查面积达5058.9ha,共抽查了15163株果树的1978419个果实。结果在上述地区连续三年未发现该虫。结合对CAB图依据文献的核查,发现其错误引用丁资料。因此,本文论证了我国东部地区无苹果蠹蛾的分布,CAB图应予更正。
