Abstract
Studies were made on the water loss as determined by weight loss has been quantitatively calculated per mg of the body weight of 8, 12, and 16 days old larvae of Prodenia litura under the influence of 1 % DDT, Rogor and Ekatox with dosage of 144.7, 173.3, 192.5 and 243.7 μ mg per larva respectively on the tarsi of each larva with microapplicator equipped with hypodermic tuberculinin syringe of 25 gauge.Ekatox treated larvae gave the quickest moribund conditions and maximum percentage of weight loss, generally 3 times more weight to that of controlled tests. Weight loss was influenced by age and dosage of the insecticides.Zusammenfassung: Gewichts‐ und Wasserverlust bei Raupen von Prodenia litura Fabr. unter dem Einfluß organischer InsektizideEs wurde der Wasserverlust determiniert als Gewichtsverlust bei 8, 12 und 16 Tage alten Raupen von P. litura unter dem Einfluß von 1%igem DDT, Rogor und Ekatox bei einer Dosierung von 144,7, 173,3, 192,5 und 243,7 μ mg pro Raupe festgestellt. Verwendet wurde ein Mikroapplikator mit hypodermischer Tuberculin‐Flüssigkeit. Mit Ekatox behandelte Raupen starben am ehesten und zeigten den größten Gewichtsverlust, etwa 3mal so hoch wie bei Kontrolltieren. Alter und Insektizid‐Dosis beeinflußten den Gewichtsverlust.This publication has 10 references indexed in Scilit:
