The parasitic wasp Encarsia formosa is an effective biological control of greenhouse whiteflies [Trialeurodes vaporariorum]. But temperatures mustn't be allowed to fall below 24 degrees Centrigrade/75 degrees Fahrenheit. Otherwise, the biological control dies before the pest because the lower temperatures keep the wasp from reproducing.
Answer
The above answer is correct. If you are unable to hold the required temperature try
using pots of Tagetes dotted around. They don't kill the whitefly but the whitefly dislike the smell and go elsewhere.

What are two major forms of biological control in organic gardening?
Microbial control by the use of such microorganisms as Bacillus thuringiensis and the release of predators such as the parasitoid wasp Encarsia formosa are two major forms of biological control in organic gardening. Microbial control is particularly effective against bagworms, caterpillars, hornworms, and loopers. Predatory release of Encarsia formosa particularly is effective in controlling greenhouse whiteflies [Trialeurodes vaporariorum].

What is a biological control of whiteflies?
Encarsia formosa parasitic wasps are an effective biological control of whiteflies.Specifically, biological controls tend to be carried out in one of two main ways. One is the introduction of predatory micro-organisms, such as in the use of Bacillus thuringiensis var. san diego to control infestations of Colorado potato beetles. Another is the introduction of predatory insects, mites or nematodes. The Encarsia formosa parasitic wasp is an example of the latter form that biological controls may take.
