熊蜂授粉与丽蚜小蜂联合应用对口感番茄品质及白粉虱防治效果的影响OA

To investigate the synergistic effects of the combined application of bumblebee(Bombus terrestris)pollination and the parasitic wasp Encarsia formosa on both fruit quality and the control efficacy against the whitefly(Bemisia tabaci)of greenhouse-grown flavorful tomatoes,using eight flavorful tomato varieties as test materials,an experiment was conducted in greenhouses.Plants were divided into a treatment group(bumblebee pollination+E.formosa release)and a control group(manual hormone application+chemical control),and the two groups were compared and analyzed for fruit set rate,malformed fruit rate,average single fruit weight,quality indices(lycopene content,soluble solids content,titratable acidity content,sugar-acid ratio),and the population dynamics of adult whiteflies.The result showed that,compared with the control group,the combined treatment significantly or extremely significantly increased the tomato fruit set rate(by an average of 5.7％),and significantly or extremely significantly decreased the malformed fruit rate(by an average of 5.6％).Simultaneously,the combined treatment enhanced the average single fruit weight(by an average of 6.10％)and fruit quality.Specifically,the contents of lycopene and soluble solids,and the sugar-acid ratio were significantly increased by an average of 6.14％,22.42％and 19.75％,respectively.Regarding pest control,the release of E.formosa provided sustained suppression of whiteflies,achieving a corrected control efficacy of 31.51％by the end of the growth period,indicating satisfactory control effectiveness.The combined application of bumblebee pollination and E.formosa can synergistically achieve the dual objectives of'quality improvement'and'pest control'for greenhouse-produced flavorful tomatoes.
