| Investigating predatory insect biodiversity in intercropping systems is essential for sustainable pest management. This study aimed to evaluate the effect of intercropping patterns of safflower and chickpea on the biodiversity of predatory insects. The experiment was conducted using an RCBD with 11 treatments and 3 replications at the research farm of the Kurdistan University, Iran. The experimental treatments included sole cropping of safflower and chickpea, replacement series with ratios of 4:4, 2:2, 1:1, 3:1, and 1:3, as well as additive series with 20% and 40% chickpeas, each in two configurations: (I) within the rows and (II) around the rows of safflower. To collect and estimate the abundance and diversity of insects in the different cropping patterns, insect nets and pitfall traps were employed. Among the collected samples, five important families of natural enemies of pests—Syrphidae, Carabidae, Coccinellidae, Staphylinidae, and Chrysopidae—were selected for analysis of their diversity and abundance. The highest number of chrysopidae, carabidae and coccinellidae was observed in the 1:1 intercropping pattern with averages of 41, 21.67 and 14.33 individuals, respectively. The highest number of individuals of the Staphylinidae family was observed in the 4:4 cropping pattern, with an average of 19.33, and the highest number of individuals of the Syrphidae family was observed in the pure safflower crop with an average of 9.33. In terms of biodiversity, based on both Shannon-Wiener and Simpson indices, among the different intercropping patterns, the 3:1 and 1:3 patterns (with averages of 0.747 and 0.744 according to the Shannon-Wiener index and 5.57 and 5.43 according to the Simpson index, respectively) showed superiority over other intercropping patterns. Overall, the results showed that safflower-chickpea intercropping is able to increase the biodiversity of natural predators in agricultural ecosystems. This can be considered as one of the practical and important strategies for biological pest control. | ||
