Phytoseiid predators as potential biological control agents for Bemisia tabaci

Predatory mites found to co-occur with whiteflies in the Middle East for control of B. tabaci indicate that some of the species should be capable of suppressing local populations of whitefly, and the ability of predators to use alternative food was tested.

Phytoseiid predators of whiteflies feed and reproduce on non-prey food sources

Biological control of whiteflies may benefit from both pollen and honeydew because these non-prey food sources have a positive effect on the life history of the two predator species, especially E. scutalis.

Pollen subsidies promote whitefly control through the numerical response of predatory mites

Pollen is added to populations of predators and whiteflies on isolated cucumber plants to show that the control of whiteflies by A. swirskii can be improved by supplementing the predators with pollen, and increased control is found.

Phytoseiid Predators Suppress Populations of Bemisia Tabaci on Cucumber Plants with Alternative Food

It is shown that both predators are able to suppress whitefly populations on isolated cucumber plants in a greenhouse, showing that the two phytoseiid species are promising biocontrol agents of B. tabaci on greenhouse cucumber.

Phytoseiid predator of whitefly feeds on plant tissue

This study investigates whether plant feeding occurs in the two phytoseiids Euseius scutalis and Typhlodromips swirskii, which are natural enemies of whiteflies and suggests that plant feeding is indispensable for E.Scutalis.

Herbivore host plant selection: whitefly learns to avoid host plants that harbour predators of her offspring

It is shown that adult females of a small herbivore, the whitefly Bemisia tabaci, can learn to avoid plants with predatory mites that attack only juvenile whiteflies, while they accept host plants of the same species without predators.

How predatory mites find plants with whitefly prey

The searching behaviour of two species of predatory mites, Typhlodromips swirskii and Euseius scutalis, known to feed on immature stages of the whitefly Bemisia tabaci Gennadius, is investigated to generate spatial patterns in the dynamics of predator and prey.

Short communication. Susceptibility of Phoenix theophrasti (Palmae: Coryphoideae) to Rhynchophorus ferrugineus (Coleoptera: Curculionidae) and its control using Steinernema carpocapsae in a chitosan…

Gummy secretion was observed in both naturally and forced infested palms indicating the existence of antibiosis in this species, and curative applications with the entomopathogenic nematode Steinernema carpocapsae in a chitosan formulation in early infested P. theophrasti palms managed to reduce insect’s activity and could help the palms to recover.

Vulnerability of Bemisia tabaci immatures to phytoseiid predators: Consequences for oviposition and influence of alternative food

The vulnerability of immature stages of B. tabaci was quantified by assessing the rate of predation on each of the immature stages when offered alone at a density high enough to allow for a maximal predation rate, and the per capita predation rates, the oviposition rates of phytoseiids, as well as the percentage of predators feeding and the percentage ovipositing decreased with increasing stages.
