Trichlorphon dusts in various concentrations were applied by means of a dusting box, either onto potted corn seedlings in 2-3 leaf stage on which larvae of the oriental armyworm were then taken to feed, or directly onto the larval bodies in containers which were then transferred to untreated potted corn seedlings. The above treatments were made at a dosage of 2.25 g. of dust per square meter, and the mortalities were counted after a period of 24 or 48 hours.

Trichlorphon dusts in various concentrations were applied by means of a dusting box, either onto potted corn seedlings in 2-3 leaf stage on which larvae of the oriental armyworm were then taken to feed, or directly onto the larval bodies in containers which were then transferred to untreated potted corn seedlings. The above treatments were made at a dosage of 2.25 g. of dust per square meter, and the mortalities were counted after a period of 24 or 48 hours. The results showed that the differences in the effectiveness of the Trichlorphon dusts against the larvae among various instars were evident. The least concentrations of active ingredient in dusts, that caused 90% kill, required for second-instar, third-and fourth-instars, or fifth-and sixth-instars of the larvae were 0.5, 1.0, or 2.5 percent respectively in the treatment of dusting the worm; and 0.25, 0.5, or 1.0 percent respectively in the treatment when larvae were fed on the dusted corn seedlings. Results also showed that feeding on dusted corn seedlings was nearly twice as effective as in the case when the larvae were dusted. In all the treatments, 2.5% dust gave almost complete kill of the larvae in all the stages of larval instars. The effectiveness of Trichlorphon dusts against the third-and sixth-instar larvae at 26℃ or 27℃ respectively was higher than those at the average temperature of 14℃ for the third instar larvae or 19℃ for sixth instar larvae. The lower effectiveness of the dusts at a lower temperature condition was presumably due to the treated larvae being less active and feeding on less amount of poisoned leaf portions than at a higher temperature. Trichlorphon dusts, applied onto the corn seedlings resulted in higher mortalities of the larvae in third-, fifth-and sixth-instars under high humidity (nearly saturated) than at 50% relative humidity, and it was more evident in the higher instar larval stages. The residual effectiveness of Trichlorphon dusts on the corn seedlings against the third instar larvae was observed. Dusts applied on the corn seedlings at 26℃ after 24 hours which were then fed to the larvae, showed a decrease in effectiveness i.e., only one half as effective as the time when the seedlings were just dusted. There was no significant difference in the decrease of residual effectiveness between treatments at saturated moisture condition and 50% relative humidity. Sixth instar larvae were dusted with 2.5% Trichlorphon dust, and the larvae were later rinsed with water at various time intervals up to 24 hours. A higher mortality was obtained as the time intervals increased before rinsing.

敌百虫粉剂按每平方尺250毫克(折合每亩3斤)的撒粉量,用双重纱格撒粉箱直接撒药于粘虫体上;或先将药粉撒布于盆栽玉米苗上,然后接飼粘虫。結果表明敌百虫粉剂对不同龄期粘虫的药效有明显的不同。在26℃按致死粘虫90%以上所需最低含量計算,直接撒药于虫体,对2龄,3、4龄,或5、6龄,所需浓度依次为0.5%,1.0%或2.5%;玉米苗撒药后飼虫,对以上各龄幼虫所需浓度依次为0.25%,0.5%或1.0%。并表明玉米苗撒布药粉后飼虫的药效,約大出虫体直接撒粉的1倍。将2.5%敌百虫粉剂用这两种方法处理,都能达到或接近100%的效果。温度低至14℃或18℃时,則药效比在26℃或27℃时为低。粘虫取食撒有敌百虫粉剂的玉米叶,在26℃、接近飽和湿度的条件下,对3龄、5龄或6龄粘虫的药效都大于在同温度、相对湿度50%时的药效,而粘虫龄期越大,药效的差别較明显。敌百虫粉剂施后經24小时,其残留药效約相当于刚撒布药粉后的一半。6龄粘虫直接撒布2.5%敌百虫粉剂后,經过不同时間洗除药剂試驗,在24小时內粉剂附着时間越短,药效也越小。

The author made studies,in 1973-1977,concerning the use of high active ingredient content granular preparation of insecticides applied in reduced quantities for corn borer (Ostrinia nubilalis Hubner) control.The object was to compare the effectiveness of control using granule preparations of various relatively high proportions of active ingredient in conjunction with corresponding reduction in the amount of granules to be applied in order to be comparable on the basis of equal quantity of insecticide application per unit.The results of study showed that,to a large extent,the effectiveness of the "high content with low rate of application" was similar to that of the "low content with high rate of application".Phoxim,for example,used on the basis of 4 grams per mu,0.25kg.of the 1.6% granular preparation and 4kg.of the 0.1% granular preparation gave similar results of approximately 80% control.With the case of Parathion,on the basis of 40 grams per mu,0.5kg.of the 8% granular preparation and 4kg.of the 1% granular preparation both resulted in control exceeding 90%.Similar results were observed with Diazinon and Permethrin granules tested.The present modification of insecticide granule application may be more suitable for pest control by machinery.Laboratory toxicity tests and plant residue determination were made in connection with,and for substantiation of,field tests.

1973—1977年,作者研究了防治玉米螟颗粒剂的“高含量、低用量”问题,即在单位面积上有效成分用量相等下,探讨逐步提高颗粒剂中有效成分含量而又按比例减少单位面积上颗粒剂用量的防治效果的相关性。结果证明,在相当大的范围内,高含量、低用量可以代替低含量、高用量。每亩用辛硫磷4克时,1.6%颗炷剂每亩用0.5斤与0.1%颗粒剂每亩用8斤均可获80%左右相似的防治效果;每亩用对硫磷40克时,8%颗粒剂每亩用1斤与1%颗粒剂每亩用8斤均可获90%以上防治效果。对地亚农和二氯苯醚菊酯试验亦获类似结果。 颗粒剂应用这一改革,有利于成品化和机械施药,并可显著降低防治成本。 同时,还做了室内毒力测定及在玉米上残效作用测定,以验证田间防治效果。 近二十年来,国内、外一直把颗粒剂做为防治玉米心叶期玉米螟(Ostrinia nubilalis hubner)的有效手段。我国自五十年代末已开始研究和应用滴滴涕、六六六等颗粒剂防治玉米螟,获得了高于六六六药液灌心的防治效果(邱式邦等,1961;邱式邦等,1963;慕立义,1963)。但由于颗粒剂用量大、费用高而未能成批生产。土法生产、群制群用的颗粒剂亦存在着缺点:(1)加工时不但造粒、...
