| Abstract | ||||
| Citrus leaf miner (CLM), Phyllocnistis citrella (Stainton) is one of the most common insect pests infesting mandarin orchards. The present study was carried out to evaluate some insecticides (Proclaim-Vertemic-Radiant-Mospilan-Runner) treatments in mixture with a mineral oil against larval and pupal stages of the leaf miner to find out the effective treatment in controlling the CLM. Results revealed that, Proclaim / Chemisol mixture (92.9%) achieved the highest reduction percentage in CLM serpentine mines, which is followed by Vertemic / Chemisol (88.3) and Radiant / Chemisol (88.2) in 2014 season. In 2015, Proclaim / Chemisol (88.2) and Radiant / Chemisol (86.5) mixtures achieved the highest reduction percentage in CLM serpentine mines. Mospilan / Chemisol (85.1) mixture achieved the lowest reduction percentage in P. citrella serpentine mines in 2014. Runner / Chemisol mixture achieved the lowest reduction percentage in P. citrella serpentine mines in 2015. Percent reduction of CLM larvae were 95.1, 90.1, 87.1, 84.3 and 81.4% in 2014 and 89.6, 86.5, 83.1, 82.7 and 78.9 in 2015, after treatment by the mixture of Chemisol with each Proclaim, Vertemic, Radiant, Mospilan and Runner, respectively. In respect with the effect of the insecticide treatments on the CLM pupae, Vertemic / Chemisol mixture (86.3 and 86.6%) achieved the highest reduction percentages followed by Proclaim / Chemisol mixture (83.9 and 83.4%) in both seasons 2014 and 2015. Runner / Chemisol mixture (77.5 and 76.0%) achieved the least reduction percentage of CLM pupae in both seasons 2014 and 2015. | ||||
