Thus, protecting the right choice of plant protection products. and preserving beneficial insects has become a major ORO AGRI CARES ORO AGRI is devoted to provide solutions for growers but not at any price. It is in our DNA to care about the environment, the user and the health of consumers. That is why we focus on developing biologically sourced solutions. At ORO AGRI, our science is powered by nature and our products have proven to be safe for natural enemies, while showing high efficacy against crop damaging pests. This guide was designed to showcase useful information and scientifically proven results on the impact of our orange oil- based solutions on a variety of important beneficials, in order to help growers in achieving economically-sustainable and ecologically-sound pest management strategies. 2 | BENEFICIAL INSECTS AND MITES GUIDE * PREV-AM is also marketed as PREV-AM Plus and PREVAM PREV-AM is beneficial- environment- and grower-friendly Field and laboratory studies are fundamental for ORO The short-term residual activity of PREV-AM makes it AGRI to provide the most suitable and sustainable easier to incorporate into organic and IPM programs solutions to growers.

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.

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. It is widely reported in the literature as a predator of spider mites on fruit crops such as apples, peaches, grapes and raspberries.This is the only Recent predatory research mite at for WUR spider (PPO) mite controlin the Net whichherlands is available identified in a A.controlled andersoni release as a formulation.promising predator forAnderline use on aaornamental is also available plants grown as loose for gardens.material in bulk bags or cardboard tubes.
