“…Reduction in female longevity of N. longispinosus after using this acaricide, were reported (Ibrahim and Yee 2000). Shortened longevity of both treated females and their offspring may be partially explained by reduced food uptake as a consequence of acaricide effects (Hamedi et al 2009). Nymphal period of the subsequent generation was also affected by sublethal concentration that is consistent with results reported on Deraeocoris brevis (Uhler) subsequent generation of treated adults with abamectin (Kim et al 2006).…”

Traditionally estimating pesticide effects by measuring only lethal effect may underestimate the total negative effect on beneficial arthropods and sublethal effects should be assessed to estimate the total effect of their applications. In this study, sublethal effect of the acaricide abamectin (Vermectin(®) 1.8% EC, Giah, Iran) on the predatory mite Phytoseius plumifer (Canestrini & Fanzago) (Acari: Phytoseiidae) fed on Tetranychus urticae Koch was assessed in laboratory conditions. The adult predators were exposed to the residues of the acaricide on fig leaves and the LC(50) value was determined based on a concentration-response analysis. The results showed that sublethal concentrations (LC(10), LC(20) and LC(30)) of abamectin severely affected the fecundity and longevity of the treated females of P. plumifer. Furthermore, reproductive and life table parameters of the subsequent generation were affected. The results indicated that adverse effects of abamectin on population growth of P. plumifer were significant, so the results from this study can be used to develop approximate guidelines for the use of abamectin in order to minimize their impact on P. plumifer and related natural enemies.

“…It has been reported that exposure to the sublethal dose of spiromesifen reduced the fecundity or fertility of T. urticae (Marcic et al 2010), and exposure to the sublethal concentration of clofentezine decreased the hatchability of eggs produced by the surviving females of T. viennensis (Li et al 2006). In addition, exposure to the sublethal concentration of acaricides also affected the population parameters of tetranychid mites and their phytoseiid predators (Hamedi et al 2009;He et al 2011;Pakyari & Enkegaard 2015).…”

Traditional estimating only by measuring the lethal effect of acaricides may underestimate the total effects of acaricides on the pest mites. In order to investigate the sublethal effect of bifenazate on life history and population parameters of the two-spotted spider mite, Tetranychus urticae Koch, the newly emerged females were treated with two lethal concentrations of bifenazate: LC 10 (4.92 μ g/mL) and LC 20 (8.77 μ g/mL). Subsequently, the development and fecundity of the progeny generations were observed. Compared to the control, exposure to the 10% lethal concentrations (LC 10 ) and LC 20 of bifenazate severely affected the parental generation of T. urticae, including survival rate (reduced 9% and 13%), oviposition period (reduced 77.6% and 83.1%), fecundity per female (decreased 89.2% and 76.9%) and longevity (decreased 79.2% and 83.1%). Besides, the population parameters of the progeny generation from the treated females were also investigated. The results showed that the progeny generation had lower intrinsic rate of increase (r m ) and finite rate of increase (λ), longer mean generation time (T c ) compared to the control. The results suggested that the sublethal effects of bifenazate on population growth of T. urticae were significant, and the results of this study could be used as a guide for the rational use of bifenazate in the field for better managing pest mites.

“…A modification of the leaf-dip technique was used [34,39]. The sublethal concentrations consisted of LC 10 , LC 20 and LC 30 were evaluated and used for assessment of sublethal effects on biological performance of P. plumifer [34,39,40].…”

Spider mites (family Tetranychidae) are important pests of many agricultural, medicinal and ornamental plants worldwide. They possess needle-like chelicerae which pierce plant cells, often feeding on chloroplasts on the under surface of the leaf and cause upper leaf surfaces develop whitish or yellowish stippling. Additionally spider mites produce silk webbing which covers the leaves. In this chapter we present common control methods of these mites including biological control with emphasizing on the prey preference, switching behavior and mutual interference of a biological control agent, Phytoseius plumifer (Canestrini and Fanzago). Additionally the side effects of two acaricides, abamectin and fenpyroxymate, on this predator will be discussed.
