The use of beneficials for the preventive protection of crops is environmentally safe, cost-effective and progressive way to control pests in greenhouses, gardens and fields. The predator-prey relationship or parasite host has been formed between living organisms for thousands, and even millions of years, as a result the use of predatory and parasitic species is one of the most effective methods of preventing and controlling pests of plants to which they do not develop resistance.
For effective use of IPM in closed ground, it is necessary to know the following. Predatory and parasitic insects and mites are used primarily preventively for pest control, when there are not many of them and beneficials will have time to increase their population in the greenhouse. In this case the IPM is economically justified. The effectiveness of the beneficials depends on the conditions in which they are applied. In different regions, at different times of the year, the profitability of the use of certain beneficials may differ, so one should give preference to those who are more suitable for the conditions in your greenhouse. If we talk in general about integrated protection in this section, then bioproducts based on entomopathogenic nematodes and fungi will be effective only under certain conditions, namely at high humidity (90-100%) and moderate illumination (cloudy weather). Often, one beneficial controls only one or more instars of pest development, so it is desirable to use several predators against one phytophagan that will complement each other, destroying its different instars. Some predatory insects and mites can hunt one another, because of which the effectiveness of their joint use is sharply reduced. This should also be taken into account when drawing up a plan for integrated protection of crops.
Bioagents are represented by predatory mites, beetles and bugs, parasitoid wasps, entomopathogenic nematodes and other species. Each of the groups of predators and parasites has its own peculiarities of application in a closed ground.
Predatory mites include: Phytoseiulus persimilis, Neoseiulus cucumeris, N. swirskii, N. californicus, Macrocheles robustulus, Stratiollepsis scimitus.
Phytoseiulus persimilis - one of the most famous and widely used acariphages in the world. It is used mainly to control common spider mite in greenhouses, but it is effective in control of horticultural and hawthorn mites, it can eat red citrus mite (Panonychus citri) and early instars of mite Bryobia lagodechiana.
Amblyseius cucumeris (or Neoseiulus cucumeris) is one of the first commercial products that has been used to cotrol thrips (tobacco, Californian and others). Today A. cucumeris has lost its relevance in the control of these pests and continues to be used in many greenhouses.
Amblyseius swirskii (or Neoseiulus swirskii) has a wider application than the previous two mites, since it is capable of destroying two main pests in greenhouses: whitefly (tobacco and greenhouse) and thrips (tobacco, western flower). This entomophage has long proved its effectiveness by controlling the first and second larval instars of whitefly, and the larva of the first instar of thrips.
Soil predatory mites Stratiollepsis scimitus and Macrochelis robustulus control many pests that are in the upper layer of the soil and not its surface. The main area of their application is the control of sciarid and immobile larval instars of thrips.
Parasitoid wasps are represented by the species: Aphidius colemani, Encrasia formosa, Eremotcercus eremicus, Anagyrus pseudococcus and others. Aphidius colemani parasitizes on various kinds of aphids: peach, cotton and tobacco. Encrasia formosa and Eretmocerus eremicus control the whitefly, parasitizing and eating the pest larvae. Anagyrus pseudococcus is a parasite of grape and citrus mealybugs.
Macrolophus caliginosus and Orius laevigatus are predatory bugs. Predatory bugs have a wide diet, they eat spider mites, eggs of moths, larvae of thrips and other pests. Macrolophus caliginosus in the greenhouse is used primarily to control the whitefly and the Tuta absoluta on tomato. Orius laevigatus is used to control thrips in greenhouses.
Predatory bugs used in greenhouses include: twin spot ladybird, Delphastus catalinae, Cryрtolaemus montrоuzieri. Predatory beetles and their larvae cope well with pest outbreaks, because they need a lot of prey to develop their own population. Twin spot ladybird eats melon, peach, potato and bean aphids. Delphastus catalinae is effective in sticky foci of whitefly, where parasitic wasps (Encarsia, Eretmocerus) do not cope, because they can be sticked. Cryptolaemus montrоuzieri is the main predator of mealybug.
Entomopathogenic nematodes are represented by species: Heterorhabditis bacteriophora, Steinernema feltiae and Steinernema carpocapsae. Nematodes are supplied in the form of a water soluble biopreparation that contains larvae of the bioagent in an inert material. After processing the plants with a solution of the biopreparation with entomopathogenic nematodes, they are active (through trachea and anus) or passive (if swallowed) pathway into the phytophagous host. Inside the pest, nematodes begin to feed on its contents, while secreting the products of vital activity containing pathogenic microorganisms for the host.
