Conditions
Macrolophus has a long generation time even at 23°C and populations can take time to build up (slower at low temperatures). Storage
» Ideally use on day of receipt, may be stored for a short time in darkness at 8-10°C. Technical Information
Macrolophus caliginosus adults are bright green in colour with red eyes and long green antennae. They are up to 6mm in length with long legs to allow it to move quickly. Very young stages are yellowish green but will turn green before reaching adulthood. IMPORTANT NOTE: Macrolophus can suck plant sap in the absence of other food. Economic damage to tomatoes is rare but the coincidence of the following conditions can result in disturbance of fruit set: high numbers of Macrolophus per plant, little prey present, weak fruit setting, tomato cultivar (cherry and smaller truss tomatoes more susceptible). This product will only be supplied for use in tomato crops and a disclaimer must be signed by the customer (a copy of the disclaimer is available on request).
