The white leafhoppers Thaia subrnfa (Motschulsky) mostly breed two generations a year in Dong-yang County of Zhejiang Province, where large areas of double-cropping rice blend with small part of middle or single late cropping of rice. The emergence peaks of the first and second generations of the leafhoppers appear from the end of June to the middle of July on the early rice and from the end of August to the middle of September on the late rice, respectively. The majority of the second generation adults...

The white leafhoppers Thaia subrnfa (Motschulsky) mostly breed two generations a year in Dong-yang County of Zhejiang Province, where large areas of double-cropping rice blend with small part of middle or single late cropping of rice. The emergence peaks of the first and second generations of the leafhoppers appear from the end of June to the middle of July on the early rice and from the end of August to the middle of September on the late rice, respectively. The majority of the second generation adults would hibernate and small portions of the population which emerge earlier may complete the third generation.This insect pest seems to breed only on rice and the overwintering adults usually concentrate in the early rice nurseries and have the highest fecundity. Since they feed on the top leaves of rice seedlings, the anthers regard the nursery stage will be the appropriate time for carrying out chemical control.

白翅叶蝉(Thaia subrufa Motschulsky)在浙江省东阳县,一年大部发生二代。第一、二代成虫分别于6月下旬至7月上、中旬和8月下旬至9月中旬盛发于早稻和双季晚稻,第二代成虫大部分越冬,少数早发的才能发生第三代。第一、二和三代卵历期分别为17—19、11—12和15一19天,若虫历期分别为19、16和24天。成虫4℃开始活动,10℃开始取食,15℃开始羽化和产卵。卵开始发育温度在20℃左右。成虫无孤雌生殖现象,产卵前期在第一、二代分别为23和17天,越冬成虫则长达6—8月之久。每雌产卵量以越冬代最高,以后各代急剧下降。越冬后成虫在4月下旬几乎全部集中于早、中稻秧田,产卵盛期在5月即早稻本田分蘗期。繁殖寄主仅限于水稻。 因白翅叶蝉具有这些生物学特性,所以防治适期为早季秧田。1964—1965年在东阳县早季秧田大面积防治结果,可减低早、中稻本田虫口90%以上,且能压低双季晚稻田的虫口密度。

This paper deals with the influence of temperature on the development and emergence of Trichogramma spp. For T. confusum and T. closterae, the temperature for development ranges from 15° to 35℃, the suitable temperature lies between 20° and 30℃ and the optimal temperature is about 24° to 26℃ .

This paper deals with the influence of temperature on the development and emergence of Trichogramma spp. For T. confusum and T. closterae, the temperature for development ranges from 15° to 35℃, the suitable temperature lies between 20° and 30℃ and the optimal temperature is about 24° to 26℃ . In the suitable temperature range the duration of development is inversely related to the rise of temperature. It is advisable to propagate Tri-chogramma in the optimal temperature where wasps with higher vitality and fecundity can be obtained.The developmental threshold of T. confusum parasitizing the eggs of Corcyra cephalo-nica is 11.6℃ and the thermal sum of development is 152 day-degrees. The developmental threshold of T. closterae is 10.5℃ and the thermal sum of development is 172 day-degreess. The number of parasites in the host egg, the kind and quality of the host eggs and the ambient temperature are the factors influencing the rate of development of Trichogramma.In natural condition the adult wasps usually emerge in the day time; this process is influenced by increasing tensity of light and emergence peaks in the morning. The relation between the time of emergence of the population during the whole period and the number of wasps emerging forms a curve with the highest peak at the beginning which is followed by two other peaks in decending order. Nearly 97% of the emerged population would be included in these three peaks. Individuals emerging in the first peak have higher vitality and fecundity.

赤眼蜂的生长发育温度大致为10—35℃,可区分为全期正常发育温度(16—33℃);部分虫期发育温度(10—11℃);全期发育阀限温度(12—15°及34—35.5℃)。全期正常发育温度尚可划出发育适温区(20—30℃)及最适温区(24—26℃)。在适温及最适温区,赤眼蜂的发育速率随温度的升高而稳步上升。拟澳洲赤眼蜂温度每增长5℃,发育速率增长21—23%。在最适温区或适温区下繁殖,生长发育最好,羽化率最高。在适温区以外,赤眼蜂的生长发育较大幅度地向不利方向变化,发育时间延长,发育速率减慢。赤眼蜂个体发育所需的时间十分悬殊,影响因素有接蜂时间、寄生量、卵粒大小及质量以及气候环境等。拟澳洲赤眼蜂的发育始点为10.6℃,有效积温为157日度;舟蛾赤眼蜂为9.6℃及176日度。 赤眼蜂群体羽化的时间,在自然环境下以日间为多,并受光线的影响常在晨间形成羽化高蜂。在适温下群体羽化的时间-数量关系呈主蜂前移的波形曲线。群体羽化过程一般常有三个明显的周期,形成三个羽化高峰;同一群体,每一周期的羽化高峰,在时间上常有同步现象。有97%以上的个体在三个羽化周期内完成羽化。第一周期内羽化的个体是群体中生活力最强的个体。

Water temperature shows a marked influence upon the incubation period of the eggs of the two species. Within the range of 20—35℃, the higher the temperature, the shorter is the incubation period. The curves of egg incubation rate of both species related to temperature are logistic. They can be expressed respectively by the following formulas:N_1+=1+e~(4.9347-0.1872t)/0.1095 and N_h=1+e~(5.2077-0.2117t)/0.1104 Where, N_n, N_h—rate of D. niedashui and D. hupehensis respectively; t—temperature.When the water temperature...

Water temperature shows a marked influence upon the incubation period of the eggs of the two species. Within the range of 20—35℃, the higher the temperature, the shorter is the incubation period. The curves of egg incubation rate of both species related to temperature are logistic. They can be expressed respectively by the following formulas:N_1+=1+e~(4.9347-0.1872t)/0.1095 and N_h=1+e~(5.2077-0.2117t)/0.1104 Where, N_n, N_h—rate of D. niedashui and D. hupehensis respectively; t—temperature.When the water temperature increases, the instantaneous hatching rate of both species increases according to the following equations: Y_n=0.0205t—0.3119 and Y_h=0.030t—0.5171.Where, Y_n, Y_h—instantaneous rate of each species; t—temperature.The miracidia of these allied species show a strong positive phototaxis and prefer swimming near the surface of water. The two cercariae shed from the gastropods 18—25 days after infection. They appear to be phototatic and suspending near the surface of water. The cercariae emerge from the snails discontinuously and in spurts at intervals. The emergence peak of the cercariae of both species appears from 8 to 10 am every day. Their emergence begin to reduce囔 by 2 pm and completely cease, after 6 pm.The populations of the two cercarie may also increase in logistic curves. They can be expressed respectively by the integral form of the logistic equations:N_n=209 362.8315/1+e~(4.3368-0.1308t) and N_h=448 376.6514/1+e~(5.8165-0.1495_t)Where, N_n, N_h—population of each species; t—day.
