Abstract
An experiment was conducted to determine the effect of intercropping of maize fodder in months of monsoon (July to
October), in Faisalabad, Pakistan, on infestation of citrus leaf miner (CLM) (Phyllocnistis citrella Stanton) and its predators.
Lemon, Kinnow, Grapefruit and Musambi intercropped with and without maize were selected for recording data on these
insects. Percent leaf miner infestation and number of predators were recorded from randomly selected branches of citrus
trees. Results showed that intercropped plots of each variety had low infestation of citrus miner and high population of
coccinellids and Chrysoperla carnea when compared with Tuckey’s Test at p<0.05. The mean CLM infestation on Kinnow
and Musambi was 8.40±0.144 and 12.72±0.171 in intercropped and 9.12±0.169 and 14.52±0.200 in wihtout intercropped
plots, respectively. Interaction of population of Chrysoperla carnea and coccinellids was non-significant for months,
varieties and intercropping but was significant within months, varieties and intercropping. The possibility of using maize
fodder as intercrop in autumn in citrus is discussed.
