Hassan and Maha Ali Abdellatif and Omaima Mohammed Abdurrahman and Abdel Gadir Mohammed Abdellah", abstract = "Cucurbits are subjected to insect pests that cause economic damage which increases upon infestation with more than one type of these pests. These pests are always subjected to application of chemical pesticides with consequent negative impacts on human health and environment, which necessitated usage of alternative control methods that are eco-friendly, economically viable and sustainable such as botanical pesticides and Integrated Pest Management (IPM), as biological control as alternative methods. The present study demonstrated the efficacy of Chrsoperla carnea to control cucurbit insect pests. It is generalist predator with voracious feeder larvae and adults feeding on pollen and nectar from flowering plants. Field application of was done at the Experimental Farm of Shendi University. Three genotypes of snake cucumber, pumpkin and watermelon were cultivated during Winter (Oct. 2022 - Jan. 2023) and Summer (Feb. - May. 2023), laid out in a Randomized Complete Block Design (RCBD) with three replicates, and insect pests were periodically collected. Temperatures and relative humidity were monitored during each sampling and monthly and seasonal variation in infestation and dominance of these pests in the three cucurbits together and or individually were examined. The overall efficacy of C. carnea instar larvae field release illustrated that releasing the three larval instars of C. carnea on the three cucurbits induced greater reductions in insect pest's infestation during Winter season of growth compared to the Summer. The study recommended further studies on the predatory lion aphid and the preparation of a product???? of C. carnea applicable in the field.", issn = "23191473", journal = "IJAIR", keywords = "Cucurbits;Insect Pests;Predator;Chrysoperlacarnea;Reduction", month = "January", number = "4", pages = "71-83", title = "{E}fficacy of the {P}redator {C}hrysoperlacarnea ({S}tephens) ({N}europtera: {C}hrysopidae) on {C}ucurbitaceae {P}ests {C}omplex at {S}hendi {A}rea, {S}udan", volume = "13", year = "2025", }
