The larvae do the damage attacking the flowers, mining the tender new leaves (Photo 1), tunnelling into the stems, and eating apical buds and young fruit. Mining by larvae in the leaves is the most common type of injury. Effect of trap design and sex attractant release rates on tomato pinworm catches. Keiferia lycopersicella, the tomato pinworm, is a moth of the family Gelechiidae.It is found in warm areas in Mexico, California, Texas, Georgia, Florida, Hawaii, Cuba, Hispaniola and the Bahamas.It has also been reported from greenhouses in Delaware, Mississippi, Missouri, Pennsylvania and Virginia.. Larvae may complete development in leaf shelters, or they may leave to enter fruit, later pupating on the ground or in soil. RESULTS. Young larvae generally feed on leaves giving them mining appearance. 68:45-51. Mating occurs soon after emergence and females lay most of their eggs within 2 days.

Watch closely for tomatoes with tiny holes in the top of the fruits. • In the 1930s the tomato pinworm reduced the California tomato crop by 25%. Here, we thus investigated the cold hardiness of Tuta absoluta larvae and adults to better explain its local overwintering adaptation strategy. The South American tomato pinworm, Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae), has been a key pest of tomato in South America since the 1950s, causing drastic tomato yield losses owing to its leaf-mining activity and through fruit infestation in solanaceous vegetables (54). Egg incubation period was about 3 to 7 days. Young larvae are yellowish-gray with a brown head capsule. Larvae are about 1/4″ in size. What Chemical Kills the Tomato Worm?.

Management of this insect pest mainly relies on insecticides because of its high infestation levels on all plant parts and life stages of tomato crop. Adults, which emerge from pupae after a few days, are active mostly at night. This phenomenon has however not been observed in the invasive South American tomato pinworm Tuta absoluta in its Mediterranean invaded areas. They give leaves a ragged appearance and enter the fruit just below the stem attachment. The larvae feed as leaf miners which occasionally invade the stems and fruits of the host plant. Moreover, no studies have looked at its overwintering survival in sub‐Saharan Africa. Tomato Pinworm, Keiferia lycopersicella (Walshingham)1 S. L. Poe2 1. How To Control Tomato Pinworms.
