Effects of temperature on a Chinese population of Amblyseius andersoni (Acari: Phytoseiidae) fed with Tetranychus urticae

Abstract

The development and fecundity of Amblyseius andersoni (Chant) fed with Tetranychus urticae Koch was studied at five different temperatures (17, 20, 25, 30 and 35 °C) and life parameters of the population were calculated. The development, reproduction, longevity, and life table parameters of A. andersoni were significantly affected by the different temperatures. The duration of the egg, larval, protonymph, deutonymph and total immature stages were reduced when the temperature increased. The total oviposition of A. andersoni was highest at 25 °C and lowest at 35 °C, and the daily average oviposition increased as the temperature increased, but few eggs were laid at 17 °C. The values of the intrinsic rate of increase (rm, 0.108--0.200), net reproduction rate (R0, 18.71--36.47) and the mean generation time (T, 14.68--29.73) significantly differed among the five temperatures. The highest net reproduction rate (R0 = 36.47) was obtained at 25 °C. The results of this study indicated that A. andersoni has a high inherent potential for the control of the T. urticae at certain temperatures.

A Preliminary Assessment of Amblyseius andersoni (Chant) as a Potential Biocontrol Agent against Phytophagous Mites Occurring on Coniferous Plants

“…Nevertheless, the r m value of the predator population estimated by Lorenzon et al [35] on P. ulmi (0.175) was higher than that on P. taxi (0.166), which may result from the longer lifespan of females feeding on P. ulmi (over 40 days) than on P. taxi (28.3 days). It is worth noting that Lorenzon et al [35] conducted tests at a slightly higher temperature (24 • C) than in this study (23 • C) and many studies have shown that temperature significantly affects the life history of phytoseiid mites [86][87][88][89]. On the basis of the above comparison, we hypothesize that P. taxi is as valuable as prey for A. andersoni as the aforementioned species of spider mite pests of orchards or vineyards.…”

The impact of entomophages on the population dynamics of major greenhouse cucumber pests

“…This is because this endophagous species is a polyphage, and a comprehensive list of the species it preys on has not been compiled. In addition, A. andersoni can be used over a wide range of temperatures from +17 °C to +35 °C (Li et al., 2019). It should be mentioned that the release rates of the predatory mite N. cucumeris were generally lower than the recommended ones during the entire observation period.…”

Effect of temperature on the life history and development of Typhlodromus athiasae Porath and Swirski (Acari: Phytoseiidae) as a predator of Tetranychus urticae Koch (Acari: Tetranychidae)

“…Similar results have been reported by studies on other Typhlodromus and some phytoseiid species. These phytoseiid mites species can survive and develop even at extreme temperatures such as 15 and 35°C (Gotoh et al 2004; Li et al 2019; Ersin et al 2021); however, no development has been reported at temperatures below 15°C (de Vasconcelos et al 2008; Lee & Gillespie 2011). These results support that phytoseiid mites have wide temperature tolerances and are quite successful at more optimum temperatures.…”
