Diglyphus isaea - Leafminer Parasites are tiny beneficial insects that kill leafminer larva in the mine and lay an egg in it. Benefits The life-cycle of these parasitoids is considerably shorter than that of their hosts. Larvae in this genus are external parasitoids of dipteran leafminers. Then the female may lay one or more eggs on the late instar leafminer larva (Minkenberg 1986). The conditions for optimum performance will be between 75-90 F with a relative humidity of around 80%.

It is an ecto-parasitoid, meaning that an egg is deposited next to its host larvae. The parasitoid larva then pupates in the leaf mine before emerging as an adult. Release RatesOnce Leafminer feeding marks are present, releases should be planned. Once the eggs hatches, it uses the dead larva as food for the next 8 days. Host feeding takes place when adult female wasp kills the larva inside the leaf mine, then lay eggs on it.

These parasitoids, work by "stinging" (laying their eggs in) the larvae of leafminers while they work in their mesophyll mines. The leafminer parasite (Diglyphus isaea) is a small, black, non-stinging wasp that searches out leaf miners on which to lay its egg. Sold Individually. D. isaea are shipped as pre-hatched, pre-fed adults. The hatching larvae will feed on the paralyzed (but living) host. While destructive leaf miners often survive pesticide treatments because they are protected inside the tunnels, they cannot escape the parasite, which raps its antennae on the mine to locate the miner. Diglyphus prefers the second and third larval stages.Adults are 2-3 mm. More information? This ectoparasitic wasp has been recorded parasitising several species of leaf mining flies in the family Agromyzidae. In New Zealand it also contributes to the control of adventive leafminer flies that feed on native plants, though it also kills native leafminer flies in native habitats. It pupates in the leaf mine. Adult female parasitic wasps of Diglyphus isaea kill second and third instar leaf miner larvae in the mine and lay their eggs next to them. Warning & Toxicities: Use within 18 hours of receipt. Adult females also kill young leaf miner larvae by using them as a food source. There are three larval stages (instars). Diglyphus isaea occurs . turn black in color.

Morphology: These insects are shiny black, about 1.5-3 mm long, with short antennae and a . Early stage of pupa of a Diglyphus sp. A female parasite can also lay between 100-200 eggs. The young parasite larvae hatch from these eggs, and will then feed on the body fluids of the larvae. They tend to kill larger larvae and feed on them. AdultsThe adults are 1.5 - 2.0 mm long. Larvae in this genus are external parasitoids of dipteran leafminers. The development of Diglyphus isaea (Walker), a parasitoid of leafminers, was studied under laboratory conditions at seven constant temperatures (10, 15, 20, 25, 30, 35, and 40C) on Liriomyza sativae Blanchard reared on cucumber (Cucumis sativus L.).

Not valid on Fly Eliminators or Gift Certificates. Each 100 ml bottle (500 adults) will treat 5,000-20,000 square feet, depending on pest levels. Egg: The adult female Diglyphus parasitoid stings the dipteran host larva to paralyze it. The parasitoid larva feeds externally on the leafminer larva, eventually killing the host. Back to Diglyphus. In order to produce eggs it punctures mainly larvae, to feed on their body fluids. Figure 4. The young parasite larvae hatch from these eggs, and will . Adult females will also feed on host larvae as a source of protein in order to produce more eggs (usually the smaller host larvae that are not large enough to support its eggs). Diglyphus isaea - Leafminer Parasites are tiny beneficial insects that kill leafminer larva in the mine and lay an egg in it. Because the host is now immobile, the mine ceases to grow.

The forewings only have a dark vein along the front edge and a small branch. Yellow-sticky traps can be used to monitor abundance of adults.Flies are more likely to land on horizontal surfaces than vertical surfaces, however, so water-pan traps might be more suitable (Finch and Collier, 1989).Allyl isothiocyanate is an important element in host acceptance, functioning as an oviposition stimulant . Photograph by Jian Li, University of Florida. After about 8 days of pupation, the adult wasp emerges through a ragged hole it bites through the surface of the mine. Diglyphus isaea is an ectoparasitic wasp that adults paralyze leafminer larvae of liriomyza species and lay her eggs next to it. - 250 Adults per bottle. Storage: Release as soon after receipt as possible. Diglyphus isaea and Neochrysocharis formosa are common idiobiont parasitoids of leafminers attacking vegetable crops that exhibit differing levels of synovigeny, and host feeding enhances their fecundity and longevity.
