Entomological museum, our university is a scientific center for the study entomofauna of Kostanai region and serves as base for professionals, involved in entomology and plant protection. According to its profile and tasks planned museum is completed, providing advice, support contact with alumni working in the regional branches of the RepublicanStateInstitutionsInstructionalCenter phytosanitary diagnostics and forecasts.

The museum in addition to a huge number of insects caught in Kostanai region, there are many entomophages species affiliation have not yet been determined. Activities entomophages saves and maintains a balance in nature. At the first stage of work with them, identified 82 species, composed exposition collection, it included representatives of 11 groups, 36 families , 68 genera. In preparing the exhibition, we relied on the material collected by us in guided hikes (1997-2009).  Owning material collected for a long time from different parts of Kostanai region , comparing their phenological observations and summarizing the literature data on the biology collected entomophages we can decide on the types that can be used against those or other pests. In the study of values ​​entomophages important to know their life and seasonal cycles, as well as the degree of conjugation with the owners of their development, taking into account the features of host plants and the prevailing environmental conditions. This allows you to more accurately determine the periods of highest abundance and activity entomophages and establish their ability to suppress the pest in the field of its propagation.

Since biological methods rely primarily on the use of entomophages need to establish their species composition determines the value for biological and integrated methods of plant protection.

Among the variety of pests of our museum visitors see useful entomophages that heals without pesticides planting grain, vegetable, fruit and other crops. It is known, for example, that to control the colorado potato beetle enough  3-4  Carabus canellatus Ill for 1m2, to prevent the mass reproduction of the second generation beetle.

Among entomophages meets  small (9-11 mm ) of the original species are voracious predators such as  Rhaphidia ophiopsis L. representatives of a very ancient group of insects. They hunted at various slow insects – fly, caterpillar e.t.c.

There are an amazing collection of the museum is a rare flightless predatory grasshopper body length is 53-75 mm, it is called steppe Saga pedo Pall. With ovipositor  Saga pedo at different depths in the ground lays stood open 7 infertile eggs that develop only females . Hunts as a predator, eats not only the small grasshoppers, but also large grasshoppers, crickets, beetles, bugs.  Saga pedo a typical representative of the steppe fauna of Northern Kazakhstan.  Decreasing form, it becomes very rare as a result of agricultural land use and in the Red Book of Kazakhstan.

In Kostanai region during development of virgin lands many steppe species of insects have reduced their numbers, as opposed to pests, whose number has increased due to the contrary mono cropping largest squares. For a long time the attention of specialists focused on the fighting against pests   rather than on the protection of useful and rare species. For example, fauna lacewing (Neuroptera) is poorly understood. We often met at the raspberries and currants common lacewing Chrysopa carnea Step., Body length of 12-13 mm, 26-28 mm wingspan. Its larvae are fast runners, grab aphids and suck , leaving only the skins of which make a cocoon before pupation. Chrysopa carnea proved effective against different types of aphids, developed methods of mass rearing using as food grain moth larvae.

It is very timely to create in our human resources specialists regional entomologists. Their task is the definition of material for economically important (for each of the natural zones) insect pests and their entomophagous. In this connection, acquire value display in the museum collections of insects Kostanai region, the species composition of which is known and defined. In collaboration with the Agricultural Research Institute Kostanai for agronomists and other specialists Entomological museum themed lectures , tours, workshops to help students to have a wonderful opportunity to get nova new information and expand  vision.

The essence of biological control is the use of natural enemies of insect pests. There are not insect species that do not have their own predators and parasites. Some insects are affected by several parasites, but not all of them can be used for biological defense.

Need to protect and promote the involvement of entomophages them on crops. One of the techniques is attracting entomophages planting nectar plants (both power supplies), such as umbrella, which feed on the flowers of flies and parasitic Hymenoptera tahin in the adult phase.

Biological control of insect pests is the most advanced in the direction of entomology, the chemicals with which fight against pests, poison the soil, plants, penetrate with agricultural products in the human body, silently causing damage to health. Therefore, this method is gaining importance and distribution. The modern approach to the management of the pest population is inherently ecological. It uses a variety of existing methods of struggle so that for each case could use some system tools and techniques that complement each other. This is numerically integrated management for  population of pests.
