    The use of MB-Solution

    Green Lacewings (Mallada basalis) for Thrips and Aphids control

    Mallada spp., better known as both green lacewings and aphid lion, is a predator that often spontaneously occurs in greenhouses and open fields. The larvae are extremely greedy and efficient against thrips, aphids and small insects. The adults are fragile, light green insects with long, transparent, fine-veined wings and golden eyes. The adult green lace wing is no predator but feeds with nectar, honeydew and pollen.

    Biology:

    In nature, there are 15-18 generations per year. The Female adults start laying eggs (approximately 20 per day). These eggs are deposited separately or in groups on short stalks (length of 0.7 mm) at the underside of the leaves (Fig. 1). After 3 days, the first larval stage develops and later on, also the second (Fig. 2) and third larval stages follow

    The third larval stage is the most important one for biological control, as it represents 80% of the total amount of food taken. The third instar has a length of approximately 0.5-0.6 mm and eats up to 50 thrips and aphids per day (total ca. 600). About 10-12 days after oviposition, the larvae pupate. One week later, the adult lacewings (Fig. 3) emerge.

    Application:

    Mallada basalis can be released in different vegetable crops, fruits and ornamentals against different kinds of thrips and aphids. M. basalis also eats red spider mites, white flies, scales and mealy bugs, small caterpillars, and eggs of moths.

    Especially in crops with a high temperature variation and/or changing relative humidity, M. basalis will not have any problems. As the larvae cannot fly, they need to be able to reach their prey via the shortest way. It is therefore important to introduce the larvae near the target pest. With M. basalis, only the hot spots or the entire open field and greenhouse can be treated. If hot spots are controlled in an early stage, there is less probability of infestation of the entire crop.

    MB-Solution:

    ekos Ecosystem presents M. basalis per 5,000 eggs on vermiculite in a 1-liter plastic bottle. M. basalis is best released in the hot spots. MB-Solution has to be used within 2 days after received.

    ·         Can be used along with other biological control agents.
