Abstract
Cotton is a major industrial crop with high
economic value, and the Southeastern Anatolia Region is the leading cotton
producer in Turkiye. However, excessive irrigation and pest infestations during
the growing period cause significant crop damage, especially from sucking pests
affecting cotton's vegetative and generative organs. This study investigated
the effects of three irrigation methods (drip, sprinkler, and furrow
irrigation) and two cotton varieties (May-455, a hairy and Fiona, a hairless
variety) on the population densities of major sucking pests in Şanlıurfa,
Türkiye in 2022. Weekly sampling monitored the populations of Thrips tabaci,
Aphis gossypii, Lygus spp., Empoasca decipiens, Bemisia
tabaci and Tetranychus urticae. The results indicated that drip
irrigation led to significantly lower populations of T. tabaci, B.
tabaci, and T. urticae, with population densities of 14.4, 16.2, and
18.4 individuals, respectively, under furrow irrigation, compared to 13.6 for
May-455 and 11.9 for Fiona cotton. The data also showed that the hairy May-455
variety supported significantly fewer T. tabaci individuals than Fiona,
with May-455 averaging 13.6 individuals compared to 11.9 for Fiona. A.
gossypii and Lygus spp. were not significantly influenced by
irrigation methods or cotton variety. The findings suggest that drip irrigation
creates conditions less favorable for pest populations due to reduced surface
moisture and humidity, whereas furrow irrigation supports higher densities due
to increased moisture availability. These results highlight the potential of
using drip irrigation and hairy cotton varieties as effective pest management
strategies, promoting sustainable cotton production while reducing reliance on
chemical pesticides.
