养鸡对果园橘小实蝇控制效果的评价

为探索果园养鸡对橘小实蝇防控效果,分析果园养鸡生态种养模式的综合经济效益。2019—2020年连续2年在广西灌阳县进行了梨园养鸡试验观察,2020年还进行了笼养鸡处理虫果试验。结果表明养鸡对梨园橘小实蝇有一定的防控效果,可减轻橘小实蝇对梨果的为害,相对防治效果为25%;笼养鸡处理虫果效果显著,虫口减退率100%,用虫果喂鸡能完全消灭虫果中橘小实蝇,是一种既杀灭害虫,又节约鸡饲料的方法。对果园养鸡效益初步分析表明：通过梨园养鸡,可增加纯收入21853元/hm²。果园养鸡是一种病虫草害绿色防治措施,是一种立体的种养模式,能有效减少农药使用量,又能满足人民对优质鸡肉的需求,提高种养经济效益,值得大力推广。

Evaluation of the Control Effect of Chicken on Bactrocera dorsalis in Orchard

The study aims to explore the control effect of chicken in orchard on Bactrocera dorsalis (Hendel), and to analyze the comprehensive economic benefit of ecological planting and breeding mode of chicken in orchard. From 2019 to 2020, the experiment of raising chickens in pear orchard was conducted in Guanyang County of Guangxi Zhuang Autonomous Region for two consecutive years, and the experiment of treating insect damaged fruits with caged chickens was also carried out in 2020. The results showed that the damage of Bactrocera dorsalis to pear fruit was alleviated, and the control effect of orchard chickens on Bactrocera dorsalis was 25%. The effect of cage-rearing chickens on insect was remarkable, the rate of insect population decrease was 100%. The insect damaged fruits were fed to chickens, and chickens could completely and effectively eliminate Bactrocera dorsalis in orchard, proving that the measure was effective for killing pests and saving chicken feed. The preliminary analysis on the benefit of raising chicken in orchard showed that the net income could be increased by 21853 yuan per hectare through raising chicken in pear orchard. Therefore, raising chickens in orchard is a kind of green control measure for pests and a three-dimensional planting and raising mode, which could effectively reduce the use of pesticides, improve the economic benefit of planting and raising, and meet the demand for high-quality chicken meat. This pest control measure is worth promoting vigorously.
