In the Hwai Valley, the rainfall is generally concentrated withinthe months of July and August, leaving the lowlands exposed for the rest of the year. This makesthe area favourable to locust multiplication. A forward or backward shift of the rainy period willaffect the locust population, for instance, in the former case, the embryonic development of thesummer generation eggs will be seriously interfered with, while in the latter case, both the summerand the fall generations of locusts will be favourably affected. It is advocated that locust control should not be limited to insecticide applications, measuressuch as irrigation, rotation and cultivation should also be taken into consideration. Only when a comprehensive control program has been carried out, will the control be thorough and lasting.

About 1650 years ago the Chinese farmers had already put biological control inpractice by using yellow citrus ants to control citrus pests. Until now the farmersof Kwangsze district, Kwangtung Province, believe that to liberate the yellow citrus antin citrus orchard is one of the most effective methods to control some of the seriousinsect pests of the citrus trees. The present work mainly deals with the utilization ofOecophylla smaragdina Fabr., in the two main citrus producing places, Hongfon andVanton in Kwangsze district. The efficiency of O. smaragdina in controlling insect pests of citrus has been ob-served in the orchards by the author. The results are as follows: When there is a sufficient number of O. smaragdina on the trees the control of thecitrus bug, Rhynchocoris humeralis Thunberg, is very effective. No damaged fruits canbe seen under the trees. O. smaragdina gives considerable beneficial results in controlling some insects withbiting mouthparts such as Podagricomela nigricollis Chen, weevils etc., but does not givevery promising results. The number of wholesome leaves on the trees where the antsare distributed is 18.37% higher than those without the ants. Of course, in both casesthe original population of the insect pests is about the same. O. smaragdina does no harm to the activity of the native predators (Rodolia rufo-pilosa Mulsant and Rodolia pumila Weise) of Icerya purchasi. These ladybird beetlesgive very effective control of Icerya purchasi as usual where O. smaragdina is distributed. O. smaragdina does not, however, control the coccids, Lowana sp., and the larvaeof cerambycids. The ants have the phenomena of symbiosis with some species of coccidssuch as Pseudococcus citriculus, Coccus sp., and Icerya purchasi. In orchards where O. smaragdina is distributed no black ants could be found ingeneral, at least the number of the latter is very few. The relation between the yellowcitrus ants and coccids is about the same as that between the common black ants andcoccids in other orchards in South China. There is no special increase in coccid popula-tion. The author concludes that O. smaragdina is not a very ideal natural enemy tocontrol insect pests in citrus orchards. When labour and insecticide could not be suppliedsufficiently the yellow citrus ants can play, however, a certain role in controlling thepests in practice.

本文对我国利用已有悠久历史的黄柑蚁在广东省广四县柑桔区作了调查,并对黄柑蚁消除害虫的实际情况作了观察。 在黄柑蚁数量足够的情况下,对柑桔大绿蝽象(Rhynchocoris humeralis Thunberg)有显著防治效果,对潜叶(虫斧)(Podagricomela nigricollis Chen)、粉绿象甲(Hypomeaes squamosus F.)、铜绿金龟子(Anomala cupripes Hope) 等,也有一定效果,凡有柑蚁分布均匀的树,健叶数比无蚁树多18.3%。 对介壳虫类,青翅羽衣(Lowana sp.),天牛幼虫等,完全无防治作用;与介壳虫类如吹绵介壳虫、棘粉介壳虫(Pseudococcus citriculus)及软腊介壳虫(Coccus sp.)有共生关系。 对吹绵介壳虫的天敌大红瓢虫(Rodolia rufopilosa Mulsant)、小红瓢虫(Rodolia pumilaWeise)的活动没有影响。有黄柑蚁的果园,黑蚁均被驱逐。 作者认为黄柑蚁并不是一种理想的天敌,目前在农药械供应不足及劳动力缺乏的地区,仍具有一定的利用价值。建议开展黄柑蚁过冬保护及人工饲养与放蚁的研究...

Delphacodes striatella Fallen is one of the important rice pests in Hupei. Accordingto our observations made in the vicinity of Wuchang, Delphacodes striatella Fallen has 6--7generations per year. It passes winter in the nymphal stage. In winter its nymphs hidein the weeds along the sides of fields and streams. The adult stage lasts 5--42 days,egg stage, 5--15 days, and nymphal stage, 9--31 days. It takes 20--42.5 days to com-plete one generation. Each female lays 62--259 eggs, depositing them in the tissue...

Delphacodes striatella Fallen is one of the important rice pests in Hupei. Accordingto our observations made in the vicinity of Wuchang, Delphacodes striatella Fallen has 6--7generations per year. It passes winter in the nymphal stage. In winter its nymphs hidein the weeds along the sides of fields and streams. The adult stage lasts 5--42 days,egg stage, 5--15 days, and nymphal stage, 9--31 days. It takes 20--42.5 days to com-plete one generation. Each female lays 62--259 eggs, depositing them in the tissue ofstalk of the host plants. The adults may be classified into two types, the long wing typeand the short wing type. According to the present study on its life history and behavior, we suggest that thepulling of the Echinochloa crusgalli in rice field is the most economical method for con-trolling this pest. Among the insecticides tested we have found 1/150--300 of 6% γ-BHC,1/1000--1500 Dipterex and 1/200--300 Endrin (19.5%) would give very successful con-trol.

灰稻虱为水稻害虫之一,据我们在武昌地区观察,此虫以成虫及若虫为害,每年发生6—7世代,以若虫期越冬。越冬期间若虫多隐藏在稻田杂草内。成虫期经过5—42天,卵期5—15天,若虫期9—31天,一世代需42.5天。每只雌虫产卵62—259粒,卵粒产于寄主植物茎内。成虫分长翅及短翅两个类型。防治方面以拔除稗草最为有效,药剂方面以1/150—300倍6%666,1/1000—1500敌百虫及1/200—300异狄氏剂有效。
