Outbreaks of green apple aphid
Green apple aphid (GAA), Aphis pomi has assumed the status of a major pest in the last few years in Jammu and Kashmir (India) with continuous seasonal outbreaks. Based on a grower perception survey conducted in ten major apple-growing districts, we assessed the reported incidence of GAA, the management practices adopted by growers, and the perceived economic losses incurred.
Overwintering of green apple aphid
apple aphid, Aphis pomi De Geer (Hemiptera: Aphididae) is a major pest of apple, with early-season infestations mainly driven by the success of overwintered eggs. To characterize its overwintering biology, a 2-year study was conducted to quantify the timing and pattern of oviposition, egg distribution along shoots, overwintering survival, and hatch dynamics.
HMO for the managemennt of green apple aphid
While petroleum spray oils (PSOs) are commonly applied at the delayed dormant stage to control San José scale and European red mite, their effect on A. pomi remains unclear. This study assessed the ovicidal and larvicidal efficacy of 2% PSO applications at the delayed dormant/green tip stage.
Insecticides for the management of green apple aphid
The efficacy of neonicotinoid insecticides was evaluated for managing green apple aphid (GAA), Aphis pomi, in apple orchards, compared to traditional organophosphates. Organophosphates showed limited knockdown effects (51.51–68.12% reduction over control) and dropped below 50% efficacy by 7 and 14 days after treatment (DAT).
