Abstract
This study evaluates the efficacy of the predatory bug (Macrolophus pygmaeus) as a biological control agent against the greenhouse whitefly (Trialeurodes vaporariorum) in greenhouse-grown pepper (Capsicum annuum). The experiments were conducted under controlled greenhouse conditions in six experimental cages, involving two treatments: M. pygmaeus + T. vaporariorum, and an untreated control (without predatory insects).
The results demonstrate that the population density of T. vaporariorum remained significantly lower in the cages with M. pygmaeus compared to the untreated control. Specifically, the average number of whiteflies was 45.7% lower within the first 14 days and decreased by over 90% in the later stages.
The results underscore the potential of M. pygmaeus as an effective biological control agent for the management of T. vaporariorum in greenhouse-grown pepper crops.
