Original research 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. Keywords Amblyseius andersoni; Tetranychus urticae; temperature; population dynamics; life table Introduction The two-spotted spider mite, Tetranychus urticae Koch, is one of the most serious agricultural pests in the world. It is a polyphagous species able to feed on more than 1,100 plant species belonging to more than 250 plant families (Migeon and Dorkeld 2010). This phytophagous mite is widely distributed and is responsible for important yield losses in cultivated crops by Received 28 January 2019 damaging leaf tissue and sucking cell contents (Grbic et al. 2011; Gerson and Weintraub 2012; Accepted 16 October 2019 Published 14 November 2019 Meck et al. 2013). This pest species develops well under conditions of high temperature and low relative humidity, displaying explosive growth (Hussey and Scopes 1985). In China, T. Corresponding author Rui-Xia Meng: [email protected] urticae only occurred sporadically before the 1990’s, and it spread rapidly later (Gu et al. 1996, Zhang and Shen 2001) and thus becomes a serious problem requiring a large use of pesticides. Academic editor One explanation for this increase is that the widespread use of pesticide has eliminated natural Tixier, Marie-Stéphane enemies especially predatory mites (Choi et al. 2004, Prischmann et al. 2005). The challenge is thus the development of biological control strategies (Bustos et al. 2016). DOI Species of the family Phytoseiidae are the most common plant inhabiting predatory mites; 10.24349/acarologia/20194344 they play an important role in the natural control of phytophagous mites and insects. Several ISSN 0044-586X (print) phytoseiid species are commercially produced for the control of pest mites (McMurtry et al. ISSN 2107-7207 (electronic) 2013). Biological control of T. urticae with predatory mites, such as Phytoseiulus persimilis Copyright Athias-Henriot, has acquired special significance for a long time (Hussey and Scopes 1985, Li Y.J. et al. Skirvin et al. 2002). P. persimilis and Neoseiulus californicus (McGregor) are the subject of Distributed under Creative Commons CC-BY 4.0 How to cite this article Li Y.J. et al.

Acarologia 59(4): 475-483; DOI 10.24349/acarologia/20194344 ongoing research in China, and have shown potential use in biological control of T. urticae (Xu et al. 2015, Wu et al. 2016). Recently, another phytoseiid mite, Amblyseius andersoni (Chant), was found on wild Chinese wolfberry in the city of Bayan Nur in Inner Mongolia in 2017 ; it is a new species recorded in China (Liu et al. 2019). Amblyseius andersoni a generalist phytoseiid species commonly found in apple orchards in several countries (Croft 1994, Duso and Pasini 2003), especially in Europe (Komlovszky and Jenser 1987; Hegyi et al. 2003, Tixier et al. 2014). A survey conducted in Syria, showed A. andersoni was a dominant species on citrus trees and on wild plants within or around orchards (Barbar, 2013). Unlike other phytoseiid mite (e.g. N. californicus and P. persimilis), adult longevity of A. andersoni is relatively long under experimental conditions (Amano and Chant, 1977). This predatory mite was often observed feeding on alternative foods (McMurtry 1992) and reaching high population levels (McMurtry and Rodriquez 1987). Some authors showed that, it can keep the population of spider mites under the economic threshold levels in fruit orchards (Duso 1992, Duso and Pasini 2003). The ability of A. andersoni to control phytophagous mites depends on several factors, such as the climatic conditions in the area (Croft et al. 1993), the morphological characteristics of plant leaves (Duso and Vettorazzo 1999), inter-specific competition (Duso 1989) and the impact of pesticides (Duso et al. 1992, Pozzebon et al. 2002). Many studies have demonstrated that temperature significantly affects predatory mite performance (e.g. functional response, mating, and oviposition behaviour), and ultimately fitness (Skirvin and Fenlon 2003, Nguyen and Amano 2009, Jafari et al. 2010, 2012, Xia et al. 2012, Wang et al. 2014). In this paper, we studied the effects of temperature on a population of A. andersoni fed with T. urticae. The life table parameters of A. andersoni were also studied providing useful data for biological control applications. Materials and methods Mite species and populations The T. urticae population used in this study was obtained from the leaves of mulberry in Salaqi, Tumut Right Banner, Baotou City, Inner Mongolia Autonomous Region (40º20’N, 110º19’E) and kept on lima bean plants in an environmental chamber at 25 ± 1 °C, 60 ± 5% RH, and L:D = 16:8. The population of A. andersoni was collected on Chinese wolfberry leaves in Urad Front Banner, Bayan Nur City, Inner Mongolia Autonomous Region (40º43’N, 108º39’E), in September 2017. The population was kept in laboratory on excised bean leaves heavily infested with all stages of T. urticae (25 ± 1 °C). The predator and prey individuals were reared for two generations before use in the experiments. Experimental setup Experiments were carried out in the laboratory at 25 ± 1 °C, 60 ± 5% RH, and L:D = 16:8. However, since leaflets on which the experiments were conducted were placed on water- saturated cotton we can suggest that humidity reached higher levels. Excised leaves infested with the different stages of T. urticae were placed dorsal side down on absorbent cotton in a large glass petri dish (12 cm in diameter and 1.5 cm in depth). The absorbent cotton was saturated with distilled water to prevent mite escape. Furthermore, the petri dish was placed on a plastic tray (40 x 35 x 2.5 cm) filled with distilled water. For the study on developmental times, ovipositing females of A. andersoni were kept on detached leaflets with abundant prey. At 16 °C, eggs did not hatch, so it was impossible start the development experiments at this temperature. Therefore, experiments were carried out at 17, 20, 25, 30 and 35 °C. Eggs were removed every 6 h from the mass rearing and placed singly on detached leaflets (4 cm in diameter) which abundant prey for 30 replicates for each temperature considered. To determine the duration of the immature stages (egg, larva, protonymph and deutonymph), inspections were carried out twice a day under a stereomicroscope until the Li Y.J.

In Europe, it is an indige- nous species, commonly found on various plants, including conifers. The present study examined whether A. andersoni can develop and reproduce while feeding on two key pests of ornamental coniferous plants, i.e., Oligonychus ununguis (Jacobi) and Pentamerismus taxi (Haller). Pinus sylvestris L. pollen was also tested as an alternative food source for the predator. Both prey species and pine pollen were suitable food sources for A. andersoni. Although higher values of population parameters Citation: Puchalska, E.; were observed when the predator fed on mites compared to the pollen alternative, we conclude that Zagrodzki, S.K.; Kozak, M.; pine pollen may provide adequate sustenance for A.

Abstract Typhlodromips montdorensis is a non-native predatory mite used for control of red spider mite and thrips, but is not yet licensed for use in the UK. Current legislation requires that non-native glasshouse biological control agents may not be introduced into the UK without a risk assessment of establishment potential outside of the glasshouse environment. This work focuses on the application of a recently developed protocol to assess the establishment potential of T. montdorensis in the UK. Further, the use of alternative prey outside the glasshouse by, Macrolophus caliginosus is examined, and interactions between Neoseiulus californicus, Typhlodromus pyri and T. montdorensis are investigated. Laboratory results demonstrate that T. montdorensis has a developmental threshold of 10.7°C, lacks cold tolerance and is unable to enter diapause when tested under two different regimes.

  • Amblyseius Andersoni
    Anderline aa Amblyseius andersoni Spider mite control Product description Anderline aa is a product containing the predatory mite Amblyseius andersoni Phytoseiidae, Acari, which is widespread in Europe and North America. It is a predator of various species of phytophagous mite, including Tetranychus spp, Panonychus spp and Eriophyidae. It is supplied as units of 25,000 mites in our patented Gemini sachets. A box holds 100 sachets, each containing a breeding colony of 250 predators at the time of packing. The sachet formulation ensures that mites continue to breed, and are released onto the crop, over a period of several weeks. How does it work? Gemini sachets are water resistant, and can be used in crops with overhead irrigation, or those grown outside. Amblyseius andersoni is a predatory mite which feeds on many types of small arthropod prey and pollen.

  • Integrated Pest Management of Western Flower Thrips
    2014 Integrated Pest Management of Western Flower Thrips © Jeremy Granadillo Kryss Facun Sarmiento 3355535 Supervisor: Dr. Kirsten Leiss Examiner: Dr. A.C.M. van Wees 4/7/2014 2 | P a g e Abstract Western flower thrips (WFT), Frankliniella occidentalis, is one of the most serious pests in agri- and horticulture worldwide. It is a highly polyphagous insect causing direct damage by feeding on plant parts such as foliage and flowers. In addition, it is a major vector for several plant viruses which leads to indirect damage. IPM programme for F. occidentalis already exist but has not led to full control of this pest. The overuse of pesticides in ornamental crops due to low tolerance to damage and pests characteristics such as short generation time, high fecundity, and parthenogenesis has led to resistance development in F. occidentalis. Moreover, its thigmotactic and cryptic behaviour makes it hard to combat chemically. Strategies that are essential part of IPM are biological, chemical and cultural control. Biotechnological advancement has made it easier to detect resistant cultivars against F. occidentalis. Moreover, host plant resistance has shown promising use and can be combined with biological control to strengthen IPM. Chemicals are still unavoidable in the horticulture for example spinosad therefore alternative natural insecticide such as pyrethrins are being used. For biological control predatory mites, bugs and entomopathogens are used while for cultural control mechanical trapping and trap plants are used. In addition, plant volatiles are combined to use pull-push strategies and to increase the efficiency of mechanical practices. The best control would be to eventually use all tactics of IPM to combat F.
