Abstract
Abstract Four chemicals were tested against Podagrica puncticollis Weise, 3 of them as sprays: Sevin (W.P. 85%) 1¼ kg/feddan, DDT (D.P. 25%), 1½ l/feddan and Aldrin (E.C. 40%), ½ 1/feddan and one as dust: Aldrin, mixed with the soil at the base of plants of each hole. Chemicals were applied 3 times at about 15‐day intervals starting on 2nd of October. Samples of 400 leaves were taken from each treatment at 3 successive dates; 15 weeks after the 1st and 2nd applications and then one month after the last application. The best results were obtained with Sevin in which 7.5 % only of inspected leaves were damaged and a mean number of 11.2 holes per leaf was obtained. Both formulations of Aldrin gave approximately similar results: percentages of 10.7 and 12 for damaged leaves and means of 11.7 and 9.9 holes per damaged leaf were recorded for the dust and emulsifiable concentrate respectively. These effects were much lower than those obtained with DDT which gave an percentage of 24.8 for damaged leaves and a relatively higher mean number of 14.5 holes per damaged leaf. Percentage of 40.7 and a mean of 25.7 were recorded for the control. Zusammenfassung Zur chemischen Bekämpfung des Baumwoll‐Erdflohs Podagrica puncticollis Weise (Col., Haltic.);m Sudan Vier Insektizide wurden gegen P. puncticollis geprüft, 3 davon als Sprays: Sevin (85%), 1,25 kg/feddan,– DDT (25%), 1,5 l/feddan und Aldrin (40%), 0,5 1/feddan sowie in Staubform Aldrin, das im Pflanzloch mit Erde vermischt wurde. Die Mittel wurden dreimal hintereinander in 15tägigen Intervallen, beginnend am 2. Oktober, ausgebracht. Es wurden Proben von jeweils 400 Blättern zu 3 verschiedenen Zeiten entnommen: 15 Wochen nach der 1. und 2. Behandlung und 4 Wochen nach der letzten Behandlung. Das beste Ergebnis zeigte Sevin, bei welchem nur 7,5 % der Blätter beschädigt waren, mit einer mittleren Zahl von 11,2 Fraßlöchern/Blatt. Beide Formulierungen von Aldrin ergaben annähernd das gleiche Resultat: 10,7 und 12 % beschädigte Blätter mit 11,7 und 9,9 Löchern/Blatt. DDT fiel dagegen mit 24,8 % Schaden und 14,5 Löchern/Blatt erheblich ab. An unbehandelten Pflanzen wurden 40,7% Schaden und 25,7 Löcher/Blatt gezählt.
