Go to distribution map The larva causes mines on the leaves, visible mainly on the upper surface. These mines widen during the second larval instar forming a translucent blotch.
As the larva matures the leaf is distorted and spun together, flowers are also affected in this way.

In fruits the larval entry hole can be detected, keferia galleries can be seen just beneath the surface; rot may also occur. Introduction Usually control methods are directed towards all tomato pests, and those for K. Efforts to control other pests may have a beneficial effect on K. Cultural Control Plant tissue, lycpoersicella fruits and packing materials where larvae may pupate should be destroyed.
Price and Poe investigated the effect of staking and artificial mulching of tomato plants on insect pest populations in southern Florida.
They concluded that damage by all species was less severe on staked plants. Schalk and Robbins found that although aluminium mulches had other benefits, fruit injury increased due to attack by tomato pinworm.
The effects of planting time and postharvest practices on K. Field plots were planted on five different dates between October and February The February planting had 25 times more fruit damage per plant than earlier plantings; the lowest keifferia occurred with October planting. Fewer volunteer plants were produced after harvesting the October-November planted crops than after later plantings.

In another study, it was observed that when Phaseolus vulgaris or squashes were planted immediately after discing and mowing a tomato site, the number of volunteer tomato plants and larval levels of K. Host-Plant Resistance Schuster tested seedlings of plant introductions of Lycopersicon for resistance to K.
In initial screenings, accessions of L. In secondary screenings, accessions of L. Biological Control The only attempt at biological control was made in Trinidad where K.

There, because native parasitoids were ineffective, parasitoids were imported from Hawaii in and releases made of three; of Pseudapanteles dignus, Apanteles scutellaris and Parahormius pallipes, but no recoveries lyopersicella made.
Chemical Control Due to the variable regulations around de- registration of pesticides, we are for the moment not including any specific chemical control recommendations.
For further information, we recommend you visit the following resources: EU pesticides database www. Borges describes it as a lyfopersicella severe pest of tomato, causing large yield losses.
For each 10 mines in the first leaf, lycpoersicella the first two leaves and in the first three leaves there was a reduction in yield of When the market price of tomatoes was considered, the economic threshold was 0.
