Biological Control in Greenhouses: A Guide

What is biological control in greenhouses?

Biological control suppresses pest insects using their natural enemies — predatory and parasitoid beneficials. Compared with chemical control it reduces residue and resistance risk and maintains a sustainable balance by protecting beneficial populations. In modern protected production, biological control forms the backbone of integrated pest management (IPM).

How is a biological control program built?

The program begins with correct identification of the crop and dominant pests. Different beneficials are used against whitefly, thrips, spider mite and aphid. The most critical factor we see in the field is timing: releases must start early and at regular intervals while pest density is low. Any chemical applications during the program must be selective and compatible with beneficials — otherwise the released beneficials die and the investment is wasted.

How are bumblebees used for pollination?

In protected crops such as tomato, bumblebees ensure effective flower pollination, raising fruit set and quality. Hive count, placement and timing are planned by flowering intensity and season. Hives per decare and application detail are covered in the bumblebee article.

What do the guides in this topic cover?

The sub-articles cover bumblebee use in greenhouses (hives per decare, when and how) and the beneficial-insect release program (predator and parasitoid schedule). For an IPM program tailored to your greenhouse, reach me through the consultancy page.
