“…Further experiments have to be done to determine whether the total crop damage of three or two pest species is less than the damage inflicted by one of the pest species. Releasing pest species in a crop is considered risky, but is accepted in some cases, such as in sweet pepper, where some growers use the ''pest-in-first'' strategy with spider mites to enhance control by P. persimilis (Hussey et al 1965; K. Bolckmans, R&D Department, Koppert BV, personal communication). Avoiding total eradication of all pest species, thereby maintaining some pest diversity, might be more acceptable for the growers than introducing a new pest.…”

To test the hypothesis that pest species diversity enhances biological pest control with generalist predators, we studied the dynamics of three major pest species on greenhouse cucumber: Western flower thrips, Frankliniella occidentalis (Pergande), greenhouse whitefly, Trialeurodes vaporariorum (Westwood), and two-spotted spider mites, Tetranychus urticae Koch in combination with the predator species Amblyseius swirskii Athias-Henriot. When spider mites infested plants prior to predator release, predatory mites were not capable of controlling spider mite populations in the absence of other pest species. A laboratory experiment showed that predators were hindered by the webbing of spider mites. In a greenhouse experiment, spider mite leaf damage was lower in the presence of thrips and predators than in the presence of whiteflies and predators, but damage was lowest in the presence of thrips, whiteflies and predators. Whitefly control was also improved in the presence of thrips. The lower levels of spider mite leaf damage probably resulted from (1) a strong numerical response of the predator (up to 50 times higher densities) when a second and third pest species were present in addition to spider mites, and (2) from A. swirskii attacking mobile spider mite stages outside or near the edges of the spider mite webbing. Interactions of spider mites with thrips and whiteflies might also result in suppression of spider mites. However, when predators were released prior to spider mite infestations in the absence of other pest species, but with pollen as food for the predators, we found increased suppression of spider mites with increased numbers of predators released, confirming the role of predators in spider mite control. Thus, our study provides evidence that diversity of pest species can enhance biological control through increased predator densities.

“…Phytoseiid mites have been shown to be effective in controlling tetranychids in a variety of situations, most notably those in greenhouses (Chant, 1961;Hussey and Parr, 1965;Gould et aL, 1969;Dixon, 1973;Markkula and Tiitanen, 1976), strawberry (Oatman, 1965;Oatman and McMurtry, 1966;Oatman et al, 1968), and deciduous fruit (Putman and Herne, 1964;1966). Huffaker et al (1970) discuss at length the functional, numerical and total responses of phytoseiid predators and their respective importance in prey regulation.…”

As the level of prey availability was increased predators expressed corresponding increases in fecundity per reproductive period, in daily ovipositional rate, in total number of prey killed per reproductive period, in daily number of prey killed per reproductive period and in female:male sex ratio. The number of prey kills per predator egg produced initially increased with increasing prey availability but levelled off at higher levels of prey availability. The total number of reproductive days also increased initially but then declined at the higher levels of prey availability.

“…Pesticide resistance in T. urticae has promoted biological control techniques based on the use of Phytoseiulus persimilis Athias-Henriot. The effectiveness of this predator in controlling T. urticae in greenhouse cucumbers was shown in the early 1960s (Chant 1961;Bravenboer and Dosse 1962;Hussey et al 1965). Later, it was reported that low relative humidity and high temperatures affect P. persimilis performance in controlling T. urticae (Force 1967;Stenseth 1979;El-Laithy 1996).…”

The effect of a fogging system on T. urticae and P. persimilis was studied in two cucumber greenhouses in northern Italy. The greenhouses were divided into two compartments, one was humidified using a fogging system and the other was not humidified. Tetranychus urticae and P. persimilis were released in both compartments but the effect of the fogging system was evaluated only on T. urticae populations. During the first experimental year, spider mites reached low densities in the ‘‘fog area’’. One year later, spider mites were more abundant in the ‘‘no fog area’’ but in the Dinero cv plots. On the Jazzer plots differences between the two areas were less marked. Since relative humidity values exceeding 90% were recorded during the night when the fogging system was not active, contact with misty water was likely the main factor affecting the reduzction of T. urticae populations in the ‘‘fog area’’
