Abstract
Field evaluation of Neem based pesticides "Entomax and Neem Azal T/S" was carried out against the jasmine moth Palpita unionalis, the olive fruit fly, Bactrocera oleae and Zeuzera pyrina (larval stage) infesting olive trees in new reclaimed area at Wadi El-Natrun (El-Behera governorate) during 2017 season. The toxic and repellent effects of Entomax and Neem Azal T/S against the previous insects were compared with the recommended pesticide (Cidial). Four sprayings during four weeks were conducted. The recommended rate application was 3.0, 1.0 and 1.5 ml/liter for Entomax, Neem Azal T/S and Cidial, respectively. The results showed that Entomax was high effective than Neem Azal T/S whereas; Entomax caused 93.2 and 70.64% for Bactrocera oleae; 97.32 and 85.76% for Palpita unionalis and 86.7 and 81.4% for Zeuzera pyrina larvae mortality and repellency, respectively. While, Neem Azal T/S achieved 90.9 and 64.24% for Bactrocera oleae; 96.37 and 80.57% for Palpita unionalis and 83.8 and 79.2% for Zeuzera pyrina larvae mortality and repellency, respectively. In addition, cidial compound achieved 96.47% mortality and 78.14% repellency for Bactrocera oleae; 96.75% mortality and 78.72 % repellency for Palpita unionalis and 82.3% mortality and 62.3 repellency for Zeuzera pyrina larvae. Entomax was the highest effect followed by Neem Azal T/S and cidial was the least effective against Zeuzera pyrina larvae The results showed that Entomax and Neem Azal T/S could be used in the integrated pest management for the olive trees pests.
