All stages of glasshouse whitefly (Trialeurodes vaporariorum) and tobacco whitefly (Bemisia tabaci), preferring eggs and larvae. Two spotted spider mites, moth eggs and thrips are also eaten. However populations develop most rapidly on whitefly. Adults can also survive for some time on plant saps.

• horizontally, in the dark

Remarks

• if there is little or no pest in the crop: feed the predatory bugs with ENTOFOOD every two weeks (max. 3-4 x)
• high densities of predatory bugs may cause particular symptoms on leaves, trusses, flowers or fruits in tomatoes. Specially in absence of prey

Appearance

Adults: size 6 mm, black with greenish abdomen, red eyes, slim, light antennae

Eggs: invisible, in leaves and stems. With a close look the top part is visible, oval shaped

Nymphs: green with red eyes, with a red stripe behind the eyes

Mode of action

Adult predatory bugs and nymphs search actively for their prey, insert their sucking mouthparts and suck out the contents.

Visual effect

If whitefly eggs, larvae or pupae are eaten by a predatory bug, only the skin remains usually in its original form with a tiny hole where the mouthparts of the predatory bug have been inserted.
