Bioagents for Greenhouses

Useful entomophages for greengouses

Useful entomophages are specially bred parasites or predators that are natural enemies of harmful species. It is possible to completely control the number of pests of cultivated plants by bioagents in a controlled environment  – greenhouses, hydroponic farms without the use of chemicals.

The use of bioagents is the most environmentally friendly method of pest control. Bioagents themselves find their victims, feed on them or lay their offspring larvae in them. Thus, the natural cycle repeats many times, up to the complete destruction of the pest population.

 

Advantages of bioagents in comparison with chemical protection:

  • does not require large energy cost;
  • helps to reduce the chemical impact on the environment;
  • does not lead to the pollution of agricultural products and environment; 
  • does not destroy ecological balance
  • provide a long-lasting effect;
  • harmless to humans, improves working conditions in the greenhouse;
  • with a high number of entomophages and entomopathogens are able to independently reduce the number of pests to a level at which they no longer cause tangible damage to cultivated plants.

Wasp-Parasite (Aphidius colemani)

It parasitizes more than 40 species of aphids, mainly  foxglove aphid, green peach aphid and  melon and cotton aphid.

Aphidius (Aphidius colemani)
A species of parasitic ichneumons from the family Braconidae, order Hymenoptera, which lay their eggs in aphids. Used in the biological method of pest control in greenhouses. Aphidius lays eggs in the body of older aphids. The female during her life (2-3 weeks) lays from 100 to 300 eggs.

The development cycle of the entomophage from egg to adult lasts 10 days at 25°C and 14 days at 21°C. The larva in the body of the aphid begins to feed on the internal tissues of the aphid. After 7 days, the larva of the entomophage creates a cocoon by attaching the aphid to the leaf, which subsequently mummifies. After another 4 days, an adult Aphidius emerges from the mummified aphid.

Aphidius kolemani detects aphids within a radius of up to 80 m from the release site. For preventive eviction, an entomophage is used at the rate of 0.2-1 individual/m2 every 7 days. Issues are carried out weekly, since in the absence of aphids, the aphidius lives for 2-3 days.

Predatory mite (Nesidiocoris tenuis)

Predatory mite, feeds on various types of whitefly (greenhouse and tobacco), eggs and caterpillars of tomato moth.

  • Dosage 1 container
  • Amount in one package 500 individuals

It is the most efficient predator. A representative of the horsefly family (Myridae) of the order Hemiptera.

All mobile stages are predatory, from the first stage to adults. One female lays an average of 60 eggs during her life.

The sex ratio is 1:1.

The life cycle from egg to adult is about 3 weeks at 27º C. The eggs are deposited in plant tissue and are therefore almost impossible to detect. Nesidiocoris can be applied both indoors and outdoors.

It feeds on various species of whiteflies, eggs and tomato moth caterpillars.

Predatory mite (Macrolophus nubilus)

Predatory mite, effective against whiteflies. Works well in tandem with Nesidiocoris.

  • Dosage 1 container
  • Amount in one package 500 individuals

Macrolophus (Macrolophus nubilis)
Predatory bug, polyphage. A representative of the family of horseflies (Myridae) of the order Hemiptera, is a promising entomophage that harms plants in protected ground.

The bug is small in size – 2.7-3.7 mm, light green, males are smaller and more mobile than females, females have a well-developed ovipositor, bent under the abdomen. Eggs are laid, like all horseflies, in the tissue of the veins and petioles of the leaves. Larval stages 5. Larvae are colored in yellowish-greenish tones.

In the laboratory (when feeding on greenhouse whiteflies), the development of macrolofus larvae occurs in 22 days. The life span of a female is up to 31 days, males up to 22 days. The fertility of females is 24-103 eggs.

The duration of development of one generation is 37-43 days.

Predator green lacewing (Chrysopa walkeri)

An active predator, feeding on various species of aphids and spider mites.

  • Dosage 1 container
  • Amount in one package 500 eggs

Predatory bug (Harmonia axyridis)

Destroys various types of aphids and spider mites.

Amblyseius (Amblyseius swirskii)

Effective against thrips, whitefly.

  • Dosage 1 container
  • Amount on one package 200 000 individuals

A species of parasitiform mites of the family Phytoseiidae from the order Mesostigmata. A common predator that feeds on pollen and various small insects, especially eggs and flies in the young stages of development and small larvae of thrips. Like other predatory ticks of the same genus, its body is transparent, pear-shaped and can vary depending on its diet. The female tick lays several eggs daily on the leaf blade of plants. At a temperature of +25 ° C, the entire development cycle from egg to adult takes about 7 days.

Optimal conditions for the development of the species are: temperature indicators above 23-25 ° C and relative humidity of at least 70%. It is not subject to the state of diapause, so it can be used in winter.
