Effect of Brassica napus, Medicago sativa, Trifolium alexandrinum and Allium sativum strips on the population dynamics of Sitobean avenae and predators in wheat ecosystem

Nadia Saeed, Nicola Mori, Andrea Battisti, Misbah Ashraf

Exploitation of Brassica, Alfalfa, Berseem and Garlic as a predator cause and reducing aphid in strips comparable to wheat diversity Inqlab–91 were evaluated with wheat having no strips as trap crop for the period of 2015. Abundance of predators belong to family Coccinelidae, Chrysopidae and Syrphidae were counted from each plant of one square foot of wheat, and the great abundance of aphid dynamics was also taken into account. The highest population of Sitobean avenae was observed on plots not having a trap cropped area with four types of strips. The number of aphids on different intercrops was found positively correlated with the maximum and minimum temperature as well as with the rainfall, while relative humidity recorded negative with all intercrops except Wheat-Brassica intercrop. The exposure of useful insects on strip-feeding aphids helped to restrict the aphid to come in intercropped area of wheat plots and retained them less than economic injury level. This clears the task of trap cropping in wheat to diminish the insecticide claim chances on the main cereal crop of vast significance.
