中文摘要:
【目的】 明确猕猴桃果园茶翅蝽Halyomorpha
halys化学防治的经济阈值。【方法】 采用田间网罩法,研究了不同虫口密度下猕猴桃果实的受害率,并根据室内药效试验及果园常规使用的化学农药计算出猕猴桃果园防治茶翅蝽的经济阈值。【结果】 在不同密度(0、2、4、6、8、10)茶翅蝽成虫和若虫的为害下,猕猴桃果实受害率差异显著(若虫:Wald χ2 = 173.433, P < 0.001; 成虫:Wald χ2 = 220.432, P < 0.001)。猕猴桃生产中使用2.5%氯氟氰菊酯和3%呋虫胺防治茶翅蝽时,成虫经济损害允许水平分别为1.22%和1.83%,若虫经济损害允许水平分别为1.22%和1.62%。成虫经济阈值分别为9.59和12.05头/百果,若虫经济阈值分别为9.11和10.59头/百果。【结论】 当每100个猕猴桃果实上,茶翅蝽成虫或若虫数量达到9头时,喷施2.5%氯氟氰菊酯或3%呋虫胺化学药剂进行防治,可实现猕猴桃果实生产最大的经济效益。
英文摘要:
[Aim] To
clarify the economic threshold for the chemical control of Halyomorpha halys in kiwifruit orchards. [Methods] Field
caging experiments were conducted to investigate the rate of damage to
kiwifruit at different population densities of H. halys, after which,
the economic threshold for controlling H. halys in kiwifruit orchards was
calculated based on laboratory pesticides bioassays and commonly used
pesticides in orchards. [Results] Under different densities
of adult and nymph H. halys (0,
2, 4, 6, 8, 10 per unit), the damage rate of kiwifruit fruits showed
significant differences (nymphs: Wald χ² = 173.433, P < 0.001; adults: Wald χ² =
220.432, P < 0.001). The economic
injury levels for adult H. halys treated with 2.5% dinotefuran and 3% cyfluthrin were 1.22% and 1.83%,
respectively, and the corresponding values for nymphs were 1.22% and 1.62%,
respectively. The corresponding economic thresholds were 9.59 and 12.05 adults,
and 9.11 and 10.59 nymphs, per 100 fruits. [Conclusion] Maximum economic benefit
can be achieved by applying pesticides such as 2.5% dinotefuran or 3% cyfluthrin
when the number of adult or nymph H.
halys reaches 9 individuals per 100 kiwifruit fruits.
