Abstract
An experiment was conducted in a field at Beni Suif Governorate to estimate the effect of intercropping of garlic plants on the population of different pests, mites, Tetranychus urticae, Thrips, Thrips tabaci and tomato leaf miner, Tuta absoluta with tomato plants during the cultivated seasons, 2014 and 2015. The obtained results indicated that the populations of the two spotted spider mite, thrips and T. absoluta recorded 144.3, 111.3, 222.4 with an average of 16.03, 12.37 and 24.71 individuals in case of tomato solely, during 2014 season, respectively, which changed to 630, 420 and 77.7 with an average number of 70, 46.67 and 8.63 individuals of the same pests in case of tomato plants intercropped with garlic, respectively in the same year. On the other hand, the population of the collected pests were 199.6, 77.4 and 261.3 individuals during 2015 season for tomato plants without intercropping with an average of 22.178, 8.6 and 29.03 individuals, respectively, while in case of intercropping system, these numbers were 498.4, 271 and 69.6 with an average of 55.378, 30.11 and 7.73 individuals, respectively when the tomato plants intercropped with garlic plants. The results showed that the correlation was positively between the factors on the population of different pests in case of tomato plants only and in case of application of intercropping method with garlic plants.
