Abstract Non-nutritive sugars such as erythritol and sucralose are active ingredients in artificial sweeteners. In the past decade, research has demonstrated insecticidal properties of non-nutritive across several arthropod species. It is now a prospective chemical control option for spotted-wing drosophila, Drosophila suzukii, one most economically important pests small fruits. D. suzukii die quicker, excrete waste large amounts, become desiccated when fed mixture sucralose. The toxicity to fly not clearly elucidated but likely due nutritional physiological failures associated with an excess fluid excretion water imbalance, caused hyperosmotic body. diuretic processes insects primarily regulated by 3 neuropeptides: CAPA hormone, hormone 31 (DH31), 44 (DH44). To explore genetic effects on we investigated regulation key genes—capa, dh31, dh44—and their 7 corresponding receptors under different dietary conditions: + sucrose, Molecular analyses revealed that expression levels capa, dh44, were significantly altered sugar-fed flies compared group only sucrose. Through trials testing synergistic peptide injection sugar consumption, DH44 consistently increased mortality all diet groups. These findings offer molecular insights development novel pest management strategies targeting suzukii.
