The size of a leaf tunnel depends on the stage of development of the leaf, the species of host [...] enemies, allowing the leaf miner population to erupt into serious numbers. In addition, the pesticides used to control leaf miners disrupt the biological control [...] according to the season, culture method and the susceptibility of the host plant. This susceptibility can also vary considerably from one cultivar to another

Macrocheles robustulus

Introduction [...] before use Spread material evenly on soil or planting medium (not on the plastic) The dosage of Macro-Mite depends on climate, crop, planting medium and [...] robustulus is used for the control of the following pests: Sciarid flies (fungus gnats) Thrips Lyprauta larvae The predatory mites feed on larvae of sciarid

The nematodes then feed and reproduce within the cadaver of the dead host, resulting in the emergence of a new [...] 35°C/95°F can be lethal Nematodes are susceptible to ultraviolet light (UV): do not use them in direct sunlight The moisture content of the soil must be kept high [...] application. When possible, irrigate the crop before and right after application For foliar application, spray the nematodes when relative humidity will exceed

Tomato leafminer

The prepupae of the tomato leaf miner ( Tuta absoluta ) are lighter than the feeding larvae and have a typical pink colouration on the dorsal [...] mine. If they leave the mines they build silk cocoons on the leaflets or in the soil. When pupation occurs inside mines or fruits, the prepupae do not build

Once in the trap they get stuck in the glue and are easy to detect, count and identify [...] sticky insert at the bottom of the trap, with the sticky surface facing upwards Fold both edges at the base of the triangle upwards Place the Pherodis capsule

This occurs in the early morning. The larva crawls into the ground to pupate. A small percentage of the larvae remain hanging on the [...] and young plants can be completely destroyed as a result of the direct damage caused by leaf miners.
