The issue of propagating parasitic insects in artificial food environments has been a challenge for researchers for a long time. Breeding one Trichogramma insect requires a lot of grain products and labor, and it takes about 40-50 days for Trichogramma and 55-60 days for Bracon to reproduce. This study aimed to develop a technology for the in vitro reproduction of trichogram, which are important parasitic entomophages in the control of various agricultural pests. The results of the experiments showed that the Trichogramma chilonis damage to nests with offspring was 82.4%, larvae emerged from eggs in 1.7 days. The larvae developed in this nutrient medium for 5.0 days, and the pupation period was 4.5 days. The average time from egg to imago was 11.2 days. The survival of hatchlings from the feeding medium lasted 5.4 days, and the male:female ratio (♂:♀) of hatched Trichograms was 1:6.

The impact of pests and diseases on agricultural crops has been amplified due to global environmental changes, resulting in an estimated adverse effect of 1.4 trillion dollars, which is approximately 5% of the world's gross domestic product. Research was conducted on various species of parasitic entomophages, such as Aphidius matricaria Hal, Aphidius gifuensis Ashm, Lysiphlebus japonica Tokawa, Aphidius ervi Hal, Lysiphlebus fabarum Marsh, Lysiphlebus fritzmuelleri Mack, and Lysiphlebus testaceipes Creeson, to determine their efficacy in controlling plant lice. The biological efficiency of the parasite in Aphis craccivora was 52.5%. As well as Aphis gossypii Glow, Acyrthosiphon gossypii Glow. parasite infection of species was 42.1-38.4%. Praon volucre Hal parasite in Aphis craccivora was 49.6%. Aphis Gossypii Glow phytophage infestation was 56.3%, while Acyrthosiphon gossypii Glow plant aphid infestation with Praon volucre Hal was 42.4%.

Проблемы, возникшие в последнее время указывают на возросшую потребность продовольствия и возникший их дефицит в мировом масштабе, а самое главное, что с увеличением населения эти проблемы будут только усугубляться. Поэтому необходимость в сельском хозяйстве будет приобретать усиленное внимание. Необходимость в интенсивном земледелии уже рассматривается давно, где немаловажную роль отводится защите растений от вредителей, болезней и сорной растительности. По данным статистически исследований в мировом масштабе по причине вредителей, болезней и сорняков теряется больше 30% урожая. Основной упор в решении этих проблем уделяется химической защите растений, с одной стороны этот метод наиболее эффективен и прост в применении, однако он несет много отрицательных аспектов.
