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...

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。

Delphacodes striatella Fallen is one of the most important insect pests on rice inNorth China. According to the results observed in the laboratory during 1959—1961 atthe vicinity of Tientsin, it possesses generally 4—5 generations per year. The eggs of thesixth generation may occur. Though these eggs may hatch into nymphs but they dieeventually in the middle of November. It appears that the different generations areoverlapping one another. The overwintering stage is the 3—5 instar nymphs of the 4th or 5th generation....

Delphacodes striatella Fallen is one of the most important insect pests on rice inNorth China. According to the results observed in the laboratory during 1959—1961 atthe vicinity of Tientsin, it possesses generally 4—5 generations per year. The eggs of thesixth generation may occur. Though these eggs may hatch into nymphs but they dieeventually in the middle of November. It appears that the different generations areoverlapping one another. The overwintering stage is the 3—5 instar nymphs of the 4th or 5th generation. Inwinter these nymphs hid themselves among those weeds along the sides of the paddy-fields, streams and the rice stubbles, and migrate partly to the soil crevices about 0.5-1cm underground. This insect possesses a migrating habit during the development, such as the nymphsafter overwintering migrate to the weeds in late February, and the adults emerged fromthe overwintering nymphs migrate to the wheat field at the end of April and producethe first generation there. The adults of the first generation migrate then to the rice-field. When the rice is harvested in September, these insect migrate back to the weedsagain. The egg stage is in an average of 6.4—19.5 day. The nymphal stage has 2—7 in-stars, but generally with 5 instars. The first instar is in an average of 3.1—8.9 days,second instar 2.6—8.8 days, third instar 2.2—11.1 days, fourth instar 2.2—10.1 days,fifth instar 3.5—6.8 days, sixth instar 3.3 days, seventh instar 2.5 days. The adults may be classified into the long-wing type and short-wing type. But ac-cording to the observations made in the field during 1958—1961, very few of the maleadults are of the short-wing type in this area. The appearance of the short-wing typeadults is influenced by the weather and food supply. The higher temperature and thefeeding on Echinochlod crusgalli Beauv. are favorable to the appearance of the short-wing type. The number of eggs laid by each female are significantly different in both types ofadults. The female of long-wing type may lay in an average of 119.2 eggs, while ofthe short-wing type 158.1 eggs. In the paddyfield, the appearance of this pests is from early June to the first decadeof July. But the abundant season is from late July to the middle of September. Duringthe abundant season, the higher temperature after precipitation is favorable to the in-crease in number of the pest. According to the observations during years 1959—1961,however, the reduced precipitation and long lighting of July and August, in North Chinacondition, are probably the main factor to stimulate the autumnal outbreak of the pest.

灰稻虱为华北稻区主要害虫之一,在天津地区每年发生4-5代,以第4代或第5代的3-4龄若虫在稻田沟边、荒地杂草、土缝、稻茬内越冬;10月中旬能出现第6代的卵期,但由此孵出的若虫至11月中旬相继死去,故第6代若虫能否安全越冬尚待进一步考查。各代的发生期间互相重迭。 当春天2月末越冬若虫迁到杂草上取食、活动;4月末羽化为成虫迁入返青麦田,并在麦田内繁殖第1代;5月末以羽化后第1代成虫转入秧田,6月初至7月初移到本田,9月中水稻收获后转到荒地或新麦苗上为害。 灰稻虱卵期平均5.5-19.5天,若虫有2-7龄,一般为5龄,各龄期随不同世代而异:平均第1龄期3.1-8.9天,第2龄期2.6-8.8天,第3龄期2.2-11.1天,第4龄期2.2-10.1天,第5龄期3.5-6.8天,第6龄期3.3天,第7龄期2.5天。成虫有长翅型及短翅型两类,在天津地区—般可见短翅型雌虫而短翅型雄虫却极为稀罕。短翅型雌虫的发生和温度及饲料有关:高温和以稗子、三棱草为饲料者,短翅型雌虫发生较多。不同翅型在不同时期的成虫其产卵量不同:长翅型成虫平均每雌产卵119.2粒,而短翅型为158.1粒。 灰稻虱在本田中的消长与水稻生育期中的温湿度有关:...

Experimental results obtained both in laboratory and in the field plots showed that the dusting of lime on leaves of infected plants was effective to a certain extent in controlling the disease. But the method is not considered to be practicable, because the disease becomes serious only in rainy seasons, and the lime applied on the plants is easily washed away by rains. Since the disease is confirmed to be chiefly carried by seeds, a field control experiment was conducted to combat the disease by using disinfested...

Experimental results obtained both in laboratory and in the field plots showed that the dusting of lime on leaves of infected plants was effective to a certain extent in controlling the disease. But the method is not considered to be practicable, because the disease becomes serious only in rainy seasons, and the lime applied on the plants is easily washed away by rains. Since the disease is confirmed to be chiefly carried by seeds, a field control experiment was conducted to combat the disease by using disinfested seeds. Seeds were collected from disease affected fields, and were treated with 0.5% solution ef granosan or ceresan for 3 hours or with 0.2% solution of granosan for 15 hours. A total of 13055 kilos of treated seeds were sown and grown in 768 mows of rice fields, while a total of 2689 kilos of non-treated seeds grown in 239 mows of rice fields were used as control. The results showed that the treated seeds gave rise to very much fewer diseased seedlings in the seed beds, and that the severity of the disease was very much lighter in the treated fields than in the control. It is thus concluded that the seed treatments stated above were not effective enough to completely disinfest the seeds. Another field control experiments by using disease-free seeds were also conducted. Seeds collected from disease-free fields were used, and the weeds especially the Leersia hexandra Swartz. around the fields were eradicated. The same experiment was carried out 4 times consecutively in a field of more than 100 mows in Canton in the years of 1956 and 1957, and again in a field of 3600 mows in Chung-Hwa district in the Spring of 1958. The results all turned out fine, and the disease was successfully controlled in all cases. But since the Leersia weed has not yet been confirmed to be a natural host of the disease, its eradication may not be necessary in the field control of the present disease. This remains to be a problem that needs further investigation.

1955年室內和大田噴撒石灰粉的防治試驗結果說明,在雨后天晴的情况下噴撒石灰粉有一定的防治效果。 1958年春曾进行了1007亩(其中对照239亩)种子消毒的防治試驗。用0.5%的西力生或賽力散燜种3小时,或用0.2%西力生浸种12小时,种子发芽率不受影响,苗期发病率显著降低,大田发病日期稍为延迟,发病严重度大为減輕。 1956—1957年早晚季連續四次(每次試驗面积100亩以上)进行换用无病田种子及剷除李氏禾杂草的大田防治試驗,防治結果都很好。1958年春季在从化县街口公社国星大队成功地完成了大面积(3600亩)的防治示范試驗,全部不发病。但是,李氏禾是否本病的野生寄主,剷除李氏禾在防治上是否必要,尚有不同看法,有待进一步研究。
