Alexander Yurievich Shagaev, a skilled expert, agronomist and consultant, shares his experience of using entomophages for control of moths in protected ground.
Against the moths you can use Trichogramma, but in March it is difficult to find its suppliers, since the production of this parasitoid is cyclical and aimed specifically on open ground. But if there is a Nesidiocoris, then you do not need anything - it's a magic remedy from everything. I more like the Nesidiocoris, but Macrolophus production is twice as cheap, so it's exactly what it's bred and advertised for. The cost of production is lower where it is produced. However, I believe that the Nesidiocoris is better. For example, to increase its population in a greenhouse in the third light zone, it is enough to make two evictions at the end of February-early March at 0.25 persons / m2 in two weeks. And Macrolophus, if I evict in the middle of March, then you need a minimum of 3 people / m2. In addition, Macrolophus needs feeding, and Nesidiokoris is not. After the disinfection of the greenhouse, the nesidiocoris has to be smashed back by the Spintor in the seedling set, because much of it remains. In 2013, at a greenhouse combine, I received a large amount of cotton soup as a gift. Nothing was coped with her, then we disbanded the Nesidiocoris. I used many entomophages, but especially liked Nesidiocoris. If you need to reduce its population so that it does not drink much juice, then I treat with Spintor, and in the autumn it is not terrible, the light becomes less and its activity decreases. When the directors were persuaded to try Macrolophus, its use turned out to be more expensive than Nesidiokoris. And chemicals were used earlier - already in July.
