Control Spray fruit trees with dormant oil to kill overwintering eggs in garden or greenhouse rinse plants with water and mist daily to suppress reproduction of mites release predatory mites Metaseiulus occiden-talis on fruit trees, Phytoseiulus persimilis or similar species on vegetables, strawberries, and flowers spray insecticidal soap, pyrethrin, or neem as a last resort, spray infested plants with avermectins. 

Predatory mite Phytoseiulus persimilis Spider mites, especially Pacific and fwo-spotfed spider mife. Release 2-10 mites per plant on strawberries or garden or greenhouse plants at first sign af spider mites repeat if necessary in 2-3 weeks not winter hardy in most of U.S. doesn t perform well on tomatoes. Reliable, except in hot, dry conditions. 

Fungi maintained on media containing sublethal concentrations of trichothedn developed resistance to this fungicide. It is assumed that a trichothecinase enzyme is formed, which inactivates the antibiotic (Sidorova, 1967). From the point of view of environmental protection, trichothedn has no deleterious effect on predator mites (Phytoseiulus persimilis). In a concentration of 0.0001%, it enhances photosynthesis, but at 0.001 % it has an inhibiting effect. It has no residual effect (Petrukhina et al. 1975).

The ecobiological properties of etoxazole are not as favorable, allowing its use in combination with predatory mites. In experiments on the comparative toxicity of some acariddes to the predatory mite Phytoseiulus persimilis and the twospotted spider mite, T. urticae, etoxazole did not seriously affect the survival and reproduc-... 

Like pymetrozine (1), flonicamid (12) has a very favorable toxicological, environmental and ecotoxic profile (Table 30.1.10) and has no major negative impact on beneficial insects and mites such as Bomhyx mori, Apis mellifera, Harmonia axyri-dis and Phytoseiulus persimilis [36, 37].

Fig. 3. Ovipositional behavior of Phytoseiulus persimilis. The first (a) and the second (b) eggs are laid, one by one, at 6-h intervals. As with all small phytoseiid mites, the egg is huge relative to the size of the gravid female. The rapid growth of large eggs may be supported by the lyrate organ, which is also large relative to the body.

Upon infestation of lima bean leaves (Phaseolus lunatus) with two-spotted spider mites (Tetranychus urticae), induction of ( )-P-ocimene (47) and a homomonoterpene, -4,8-dimethyl-l,3,7-nonatriene, occurs. A homosesquiterpene, (3 , 7 )-4,8,12-trimethyl-l,3,7,ll-tridecatetraene also has been observed (Dicke et al., 1990). These compounds attract another mite, Phytoseiulus persimilis, which is a predator of the two-spotted spider mite, a phenomenon known as indirect defense (Dicke et al., 1990 Takabayashi et al., 1991). When uninfested leaves are placed on moist cotton that had previously come into contact with leaves that had been infested (but had the mites removed), production of these compounds again occurred, providing evidence that induction of these kairomones occurs (Takabayashi et al., 1991). The...
