“…In particular, a scarcity of E. carpini (one prey offered per day) drastically reduced predatory mite oviposition, with a greater effect on A. andersoni. This predatory mite appears to have a high requirement in terms of food availability which may explain its low persistence when prey diminishes in vineyards (Duso 1989, Duso et al 2003. K. aberrans required a low amount of prey to lay eggs confirming its capacity to survive and reproduce in conditions of prey scarcity (Duso and Vettorazzo 1999;Duso et al 2009).…”

Biological parameters, prey consumption and prey conversion into egg biomass of overwintered females of the phytoseiids Kampimodromus aberrans, Amblyseius andersoni and Typhlodromus pyri fed with varying numbers of Eotetranychus carpini females or pollen were studied in the laboratory. We found that pollen and E. carpini females proved to be optimal foods for overwintered phytoseiids. In most comparisons pollen induced performances comparable to those recorded when predatory mites were supplied with 4-8 prey per day. Typhlodromus pyri and A. andersoni females survived longer when fed on pollen and the percentage of K. aberrans ovipositing females was higher with pollen than with spider mite prey. For K. aberrans and T. pyri, periods to diapause termination were comparable when pollen or eight prey per predator per day were provided. Oviposition times were long for T. pyri and A. andersoni fed with pollen.Low numbers (1-2) of E. carpini drastically reduced predatory mite oviposition, particularly in A. andersoni that showed high requirements in terms of food biomass. Results highlighted the importance of pollen for overwintered predatory mites. The results obtained can help in understanding some aspects of the biology and behaviour of the three predatory mites in vineyards.

“…In Italy, phytoseiid mites occur on grapevines even when spider mites are scarce, likely feeding on wind-borne pollen and/or preying on eriophyid and tydeid mites that exhibit seasonal increases (Duso et al 2004). On deciduous fruit trees, such as grapevines and apples, powdery mildew can also cause increases in phytoseiid mite populations when densities of spider mites are low (Chant 1959;Zemek and Prenerová 1997;Duso et al 2003). Moreover, several studies have shown that phytoseiid mites survive on honeydews produced by homopteran insects for some periods (Ferragut et al 1987;Zhimo and McMurtry 1990;Nomikou et al 2003).…”

The effectiveness of non-prey food items, such as pollen, honeydew, and microbes, in maintaining phytoseiid mite populations is widely accepted. However, the availability of such naturally occurring non-prey foods varies with the season and surrounding environment; thus, it is difficult to manipulate and maintain supplies of these food sources. A great deal of research has examined the development and reproduction of phytoseiid mites on artificial diets. Although phytoseiid mites frequently develop, several studies have detected low fecundities of adult females reared on artificial diets. Therefore, the use of artificial diets for commercial propagation is often difficult. However, the potential of artificial diets to maintain phytoseiid mite populations has not yet been evaluated. In this study, we investigated the developmental success and survival of Neoseiulus californicus (McGregor) on an artificial diet. This mite may be one of the most effective phytoseiid species used in agricultural systems for the control of spider mites. N. californicus successfully developed on the artificial diets: 93.5-100% of individuals reached adulthood 4-7 days after hatching. The survival rates of gravid adult females maintained on the AD-1 artificial diet composed of yeast components, saccharides, and egg yolk at 25 degrees C were 100, 80, and 48.9% over 36, 60, and 90 days, respectively. Moreover, >80% of the surviving females maintained on AD-1 for 36 or 60 days laid eggs after being switched to a diet of the spider mite Tetranychus urticae Koch, although they had laid few eggs during the maintenance periods on the artificial diet. Our results indicate that artificial diets can serve as a potentially useful food source for the long-term maintenance of N. californicus populations.

465The control of spider mites in protected crops is often critical due to the development of mite resistance to acaricides. Studies of the side-effects of pesticides on beneficial mites are required in order to improve integrated spider mite management. Pesticide side-effects on predatory mites of the family Phytoseiidae can be studied at the field or laboratory level. In the field, phytoseiid abundance can be related to the presence of prey and/or alternative foods, which can affect the response of predatory mites to pesticides. We investigated whether pesticide side-effects on phytoseiids may be mediated by trophic interactions. In the laboratory we evaluated the effects of two insecticides (derived from pyrethrins and Beauveria bassiana) on the predatory mite Phytoseiulus persimilis by testing the same under various exposure conditions (leaf residues, treated prey, topical application). The effects of these insecticides on P. persimilis were higher when the predators were fed with treated prey. Furthermore, we investigated the effects of pyrethrins on the predatory mite Amblyseius andersoni on vines with low or high incidence of the plant pathogenic fungus Plasmopara viticola (grape downy mildew, GDM). GDM mediated interactions between pyrethrins and A. andersoni since it is alternative food for this predatory mite. The implications of these studies for the development of toxicological methods and integrated pest management are discussed.
