Host-Plant Resistance Schuster tested seedlings of plant introductions of Lycopersicon for resistance to K. 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.
Mature larvae usually drop to the soil to pupate near the soil surface. The third and fourth larval instars feed from within tied leaves or folded portions of a leaf. The male genitalia have a sickle-shaped uncusan ovate gnathosan elongate valva with enlarged apex which is bifurcate with unequal branches, and vinculum with the posterior margin projected medially and with paired finger-like lateral processes.
Early instars of either species will be difficult to recognize with morphology. Lycopersiceloa developmental time for each stage from egg to adult is shown in the table below Elmore and Howland The effects of planting time and postharvest practices on K.

Close scouting of the crop for leafminers and frass around the calyx should detect populations lyckpersicella they reach damaging levels.

In fruits the larval entry hole can be detected, and galleries can be seen just beneath the surface; rot may also occur. Chemical Control Due to the variable regulations around de- registration of pesticides, we are for the moment not including any specific chemical control recommendations.
Once larvae have been feeding for a while, the brown granular frass can often be seen at the edge of the calyx. Keiferia lycopersicella Walshingham Insecta: All lydopersicella appear smooth skinned without any prominent hairs.
The tomato pinworm is a small, microlepidopteran moth that is often confused with closely related species, which have similar habits. Tomato, potato, eggplant, and a weed, Solanum bahamese L. Borges describes it as a very severe pest of tomato, causing large yield losses.

Keiferia lycopersicella has round to pointed microgranules. Use of locally produced and ‘clean’ transplants is recommended to avoid transplanting pest problems with the crop.

Females have the ostium with oblong sclerotization, a long funnel-shaped antrumand a large sickle-shaped signum with protruding base. Go to distribution map Life History Back to Top The developmental time for each stage from egg to adult is shown in the table below Elmore and Howland The tomato pinworm in Florida.
The cuticle at least on the dorsum of the posterior abdominal segments has round to pointed microgranules bearing short microsetae. The labial palpus is upturned. Contributors own the copyright to and are solely responsible for contributed content.
Leaf mining pinworm deposit keifeeria of their frass at the entrance to the mine; whereas, dipterous leafminers will deposit frass throughout their mines. Young larvae use silk to spin a tent. Comparative material of both species is helpful to see this difference.
