Universal feed for entomophagous
Grain moth eggs (Sitotroga cerealella) is a natural substitute for natural food for mass breeding, accumulation and maintenance of entomophagous predator population size (chrysopidae, cycloneda, phytoseiidae , ditsifus, Orius insidiosus, Lissotriton).
Established that at the time of the absence or weak settlement during plant pests scattering grain moth eggs contribute to maintaining populations of entomophagous and a significant increase of its strength (3-4 times more).
Using grain moth eggs as food does not alter the basic entomophagous biological indicators for many generations. Contact the transition to eating natural host occurs without complications and even with improved biological indicators predator (increase fertility in half or more), so the eggs can be successfully used to support populations of entomophagous, the appearance of pests in greenhouses and greenhouses, as well as for mass breeding in biological laboratories.
In low occupancy rate of plant pests cost of eggs is 50 g / ha should be feeding every two weeks. In the absence of a pest or for mass breeding entomophagous consumption rate should be increased to 100 g / ha fertilizer should be made every week.
Eggs grain moth paste 20% solution of sugar to "card" made of brown paper, cut into small squares. "Cards" on evenly hung on greenhouse plants, about 2/3 of their height, according to consumption rates of grain moth eggs. Spent "Card" can be left on the plants until the disposal of the latter.
An alternative method is to distribute the grain moth eggs in a greenhouse by spreading the leaves of plants, according to consumption rates.
