Pest - Leafminers

(Liriomyza trifolii (American serpentine leafminer), Liriomyza bryoniae (Tomato Leafminer), Liriomyza huidobrensis (Pea Leafminer), Liriomyza strigata

There are four leafminer species that have become common pests. Under normal conditions, several natural enemies effectively parasitize the larvae of these species. However, problems with leafminers have increased due to the widespread use of broad-spectrum pesticides. As with other pests, leafminers have developed a resistance to many of these chemicals.
--BIOLOGY--
Both leafminer goes through six developmental stages: egg, three larval stages, pupa, and adult. The adult leafminers are small yellow and black flies. The larvae form mines in the leaves of plants, visible as a lacework of white lines. Pupation primarily takes place in the soil.
--DAMAGE--
The larvae and female adults cause plant damage. The females make feeding marks in the leaves and lay eggs inside of them. As the larvae feed, they mine through the leaves reducing the amount of productive leaf surface area and eventually causing leaves to dry out completely. Indirect damage occurs when fungi or bacteria enter the feeding areas.
--BIOLOGICAL SOLUTIONS--
Biological control of leafminers is possible the following Koppert products: MIGLYPHUS, MINUSA, MINEX and DIMINEX.
