Eggs are deposited in leaf tissue, in a slit cut by the female. One end of the egg protrudes slightly. The egg is colorless to pale white in color, and bean-shaped in form. Duration of the egg stage is about 16 days at 15°C (59°F), 7.5 days at 26°C (78.8°F), and 4.3 days at 32°C (89.6°F).

Jun 1, 2020 · Eggs of T. palmi are microscopic and embedded within plant tissue by the sharp ovipositor of adult female. In the present study, an artificial oviposition setup has been standardized for T. palmi. Eggs of T. palmi were harvested in …

The melon thrips, Thrips palmi Karny (Thysanoptera: Thripidae), has become one of the most serious pests of eggplant, cucumber, field beans, melons, peppers, and flowers in Taiwan since its arrival in 1979 ( Chang 1995).

Life stages of the melon thrips are the egg, two larval instars, two pupal instars, and the adult. The adult, egg, and two larval stages are found on the host. Pupae occur in the soil or among leaf litter. Duration of life cycle (egg to adult) for the melon thrips is 11 days at 86 degrees and 26 days at 62.6 degrees Fahrenheit. EGGS

T. palmi exhibits all the life stages common to terebrantian thrips: the egg, larva I, larva II, prepupa, pupa, and the adult. The length of each life stage and number of eggs laid per female varies with temperature and host plant.

This datasheet on Thrips palmi covers Identity, Overview, Distribution, Hosts/Species Affected, Diagnosis, Biology & Ecology, Natural Enemies, Impacts, Prevention/Control, Further Information.

As with other thrips species the life cycle from egg to adult is dependent on temperature. The full cycle can take about 15 days (Lewis, 1973) to over a month and adults may live for more approximately two months producing several generations in one …

Sep 5, 2019 · Melon thrips (Thrips palmi) is the principal insect pest of vegetable and ornamental plants worldwide. In addition to inflicting feeding injuries on host plants, they act as vectors of economically damaging tospoviruses.

Life stages of the melon thrips are the egg, two larval instars, two pupal instars, and the adult. The adult, egg, and two larval stages are found on the host. Pupae occur in the soil or among leaf litter. Duration of life cycle (egg to adult) for the melon thrips is 11 days at 86 degrees and 26 days at 62.6 degrees Fahrenheit. EGGS

Eggs are deposited in plant tissues sepa rately. Larvae have two stages, under both of which they feed on plant tissues. The second instar larvae, when matured, fall to the ground, where they moult to prepupae and to pupae as well in the soils.
