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.

Frequently asked questions
Does biological control fully replace chemical spraying?
Usually no; in integrated pest management biological control is the backbone but can be supported with selective, beneficial-compatible products to minimise residue and resistance risk.
When should beneficial releases start?
Start releases early, while pest populations are low. Late releases make it much harder for beneficials to suppress the pest. See the beneficial-insect release schedule for detail.
What do bumblebees do?
Bumblebees pollinate crops such as tomato, improving fruit set and quality. Hives per decare and placement are planned by crop and season.
Which crops use biological control?
It is common in protected tomato, pepper, cucumber, eggplant and ornamentals. The beneficial mix is chosen by crop and pest profile.
