Abstract:
Cauliflower is grown all year in the state of Punjab, in one part or other part of region. Insect pests are one of the most serious restrictions for production failure in this crop. Insect pests are critical because they cause significant economic losses in the cauliflower crop. Insect pest destruction affects both the quality and quantity of cauliflower crops, resulting in poor returns to farmers. Farmers are primarily reliant on the application of various insecticides and pesticides to protect their crops from losses caused by insect pests. Cost-effective crucifer production has been almost impossible in some parts of the world due to insecticidal control failures. As a result, efforts to create integrated pest management (IPM) programmes, which are primarily based on manipulating natural enemies, have increased across the world. Natural enemies play an important role in the control of cauliflower insect pests. The natural enemies such as the mantis, seven-spotted lady beetle (Coccinella septempunctata), spiders, and ants, which are general aphid predators, may provide sufficient control. Among hymenopteran parasitoids, Diadegma fenestralis (Holm.), Diadromus collaris (Gravenhorst) and Cotesia spp. The dominant species of diamondback moth where about 90% of the parasitism detected was caused by Diadegma spp. and Cotesia plutellae (Kurdj.) in Ethiopia. This paper investigates the effectiveness of a variety of parasitoids and predators against cauliflower insect pests, as well as their interactions and possible integration into existing IPM systems.
