The green lacewing, Chrysoperla carnea (Stephen) spread in most agroecosystems. It feed on various soft bodies pests. The conservation of the predator by attracting it to the field are considered among the most important strategies of using it in the biological control of pests.
The study was conducted in the fields of cotton crops in Hama Governorate, central Syria. In order to test the effect of some attractants on increasing the number of the predator C. carnea in cotton fields, the attractants protein hydrolysates, tryptophan, 2-phenyl ethanol, and methyl salicylate were tested using white sticky traps in the cotton field in 2017 and 2018, and by spraying some attractant on the vegetation of the plants in 2018. In 2017 2-phenyl ethanol and tryptophan were the most effective attractant of lacewing adults with an average of 6.3 and 6 adult/trap respectively compared to 0.67 and 0.33 and 0 adult/trap in methyl salicylate and protein hydrolysate and control traps. In 2018, the solution of 5% protein hydrolysate was the most effective attractant of the predator with 13 adult/trap. Testing two concentrations of tryptophan spraying on plants in a field cage (1.25-2.5g/800ml) led to increase the number of predator’s eggs three and seven days after spraying on treated plants compared to the control, the average numbers of eggs three days after spraying Tryptophan were 4.80, 4.20, 1.80 eggs/plant for the two concentration and control respectively. The average number of eggs one week after spraying was 4.20, 3.80, 1.60 egg/plant for two concentration and control respectively, but spraying tryptophan had no effect on predator eggs after 9 days. Spraying 2-phenyl ethanol on plants didn’t lead to increase the number of predator eggs compared to control after 3, 7 and 9 days.
