This wasp targets Tuta absoluta and 9 species of Liriomyza spp leafminers on a broad variety of crops.
Diglyphus isaea belongs to the family Eulophidae. It parasitizes leafminer larvae in both field and greenhouse crops. The parasitic wasp is an ectoparasitoid, meaning that it lays eggs at the vicinity of the host (second and third instar larvae of the leafminer) and not actually in the host.
Tuta absoluta has very rapidly become a
massive pest to home gardeners and
commercial growers alike. Losses typically start at 50% and very rapidly
increase to a point where the entire crop is lost. Tuta can produce in excess of 10 generations in a single season, with a single female capable of laying 200-300 eggs.
eggs, adults and pupae can overwinter in the soil, however this is not a
necessity, as they will not go dormant if there is food available for
Tomato, eggplant, beans, pepper, chillies, potato, squash, cucumber, beetroot, swiss chards, pea and watermelon.
Diglyphus isaea is a small wasp (2 mm long) black with a
metallic green sheen bearing short antennas. Females are slightly bigger
than males and can be recognized by a wide black-coloured band on the
back pair of legs while males have two black-coloured small bands. Eggs
are of elongate shape, transparent white-coloured and measure 3 x 0,1
The adult parasitoid performs especially well during the hot conditions of mid-summer (temperatures above 30°C). It can also feed on the body fluids of the leafminer larvae to obtain protein – an essential ingredient of its diet – to maintain egg production. This activity, known as predatory host feeding, kills the host, in addition to mortality inflicted by active parasitization.
- BioDiglyphus is packed in a container of 125 cc containing 250 adults.
- If necessary, BioDiglyphus can be stored for 24 hours at a temperature of 6-8°C from the minute of arrival until release. The product should never be frozen.
- BioDiglyphus is compatible with BioGrow products sold by Livingseeds.
- BioDiglyphus is applied while walking in between the plants, opening the container’s lid and letting the wasps fly out towards the plants.
- Application of BioDiglyphus should be carried out either early in the morning or late in the afternoon, under relatively mild temperatures.
- BioDiglyphus is shipped in isolated styrofoam boxes chilled with icepacks. This packaging must be kept intact till it reaches the end-user. When applied, the containers should be taken from the shipment package one by one and the parasitoids should be released immediately.
- The number of wasps at first introduction, as well as following introductions, depends upon the degree of leafminer infestation and the rate of naturally occurring parasitism.
- About 3 weeks following the release of the parasitoids (depending upon temperature), a clear indication of active parasitism is visible. The subsequent established generations of the parasitic wasp are expected to effectively control the leaf miner throughout the entire period of the crop.
