Diglyphus isaea

Diglyphus isaea is a highly effective parasitic wasp and the premier biological solution for controlling Leafminers (Liriomyza spp.). Unlike other predators that hunt on the leaf surface, Diglyphus is a specialized ectoparasitoid that locates leafminer larvae hidden inside the leaf tissue. The adult female stings and paralyzes the leafminer before laying an egg next to it, providing an immediate stop to leaf damage. This is a crucial tool for aroid collectors and commercial growers looking to preserve the aesthetic integrity of high-value foliage.

• Common Name: Leafminer Parasite

• Target: All major Leafminer species (Liriomyza bryoniae, L. trifolii, L. huidobrensis).

• Format: Adult wasps in a carrier bottle.

• Best For: Curative control in greenhouses, indoor gardens, and nurseries with active leafminer trails.

• Key Advantage: Fast population buildup and "host-feeding" behavior, where adults kill additional leafminers for nutrition, increasing their total impact.
