“…Reduction in settlement ratio of phytoseiid mites treated by abamectin reported in our study and several other studies too [34,36,44]. Our results along with other studies on predators of T. urticae showed that most mortality occurred in 3 days after exposure to abamectin while in the first day there was no effect or a few effects [36,[48][49][50].…”

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.

“…In labora-tory experiments, Pappas et al (2013) observed that P. finitimus may feed and reproduce on larvae of T. urticae, as well as on crawlers of the greenhouse whitefly, Trialeurodes vaporariorum Westwood. Also, the phytoseiid Phytoseius plumifer (Canestrini and Fanzago) have been mentioned as predator of tetranychid and eriophyid mites on various crops in Iran (Hajizadeh et al, 2002;Nadimi et al, 2009;Gorji et al, 2012;Khodayari et al, 2013). In a study on the life table parameters of P. plumifer on T. urticae, Gorji et al (2012) showed that the net reproduction rate (R0) was 29.6 females/female and the finite rate of increase (λ) was noted to be the highest at 30°C (1.29 day -1 ).…”

Phytoseiid mites are important for biological control of some pest species including phytophagous mites and small insects. The species, Phytoseius corniger Wainstein is one of the most abundant predatory mite in fruit orchards and urban green spaces in Razavi Khorasan province, Iran. Biological parameters of this predatory feeding on the two-spotted spider mite Tetranychus urticae Koch was studied for the first time under the laboratory conditions (25±2 ºC, 55±5 % RH and 16L: 8D photoperiod). The results indicated that the mean developmental periods for egg, larva, protonymph and deutonymph were 1.12±0.09, 0.73±0.03, 1.01±0.03, and 3.05±0.09 days for females, and 0.95±0.37, 0.67±0.39, 1.05±0.88, and 3.05±0.85 days for males, respectively. The pre-oviposition, oviposition, post-oviposition periods and adult longevity for females were 4.63±0.11, 11.63±0.16, 7.93±0.13 and 24.18±0.21 days, respectively. The females laid an average of 0.48 eggs per day, and 5.60 eggs during their life span. In addition, larvae of P. corniger may molt to the protonymph stage without feeding. Consumption rate during nymphal stage was 1.95 prey per day. The highest rate of prey consumption was recorded during the oviposition period, with an average of 3.35 prey items prey per day. Regarding life-history traits, the intrinsic rates of increase (rm) of this predatory mite 0.064±0.02 (♀♀/♀/day) and its finite rate of increase (λ), net reproduction rate (R0), generation time (T), and doubling time (DT) were 1.066±0.23 (day-1), 3±0.07 (♀♀/♀/generation), 17.14±0.11 (days), and 10.83±0.65 (days), respectively. Further laboratory and field studies regarding its diet preference and predation capacity are needed.

“…Therefore, phytoseiids can prevent prey resurgence, without the normal time lag usually associated with a numerical response [37]. Among the predatory mites of the family Phytoseiidae, we worked on Phytoseius plumifer (Canestrini and Fanzago) (Acari: Phytoseiidae) because it is an effective predator of phytophagous mites distributed in several countries such as Iran, Egypt, France, Italy, and Israel [38][39][40], but there is a little available data about acaricides side effects on this predator's performance [13]. One of the projects was the assessment of lethal and sublethal effects of two commonly used acaricides on Plumozetes plumifer [12][13][14].…”

Simply estimating pesticide effects on natural enemies of pests by measuring only lethal effects, or sublethal effects on the only treated natural enemies, may underestimate the total negative effects on them. So sublethal effects on subsequent generations should be assessed to estimate the total effects of their applications. Sublethal effects of commonly used acaricides on population growth parameters, life table parameters, and predation of the predatory mites of the family phytoseiidae were investigated. For this reason, offspring of treated females were used. Gross reproductive rate (GRR), the intrinsic rate of birth (b), the intrinsic rate of death (d), mean generation time (T), survivorship (Lx), life expectancy (ex), and prey consumption were affected in comparison with control. It could be concluded that sublethal concentrations of most applied pesticides can significantly reduce population growth and life table parameters, and this should be considered in integrated pest management (IPM) programs.
