Manduca quinquemaculata, the five-spotted hawkmoth, is a brown and gray hawk moth of the family Sphingidae.The caterpillar, often referred to as the tomato hornworm, can be a major pest in gardens; they get their name from a dark projection on their posterior end and their use of tomatoes as host plants.
Manduca sexta is a moth of the family Sphingidae present through much of the Americas.The species was first described by Carl Linnaeus in his 1763 Centuria Insectorum.. Commonly known as the Carolina sphinx moth and the tobacco hawk moth (as adults) and the tobacco hornworm and the Goliath worm (as larvae), it is closely related to and often confused with the very similar tomato hornworm ...
The eggs are initially pale green in color, but over time they turn yellowish and then grey. [9] Eggs are 0.5 mm in height and average about 0.55 mm in diameter. [9] They hatch after 66 to 72 hours of development. [10] Once larvae have breached the chorion, they spend up to 83% of eclosion making an exit hole larger than their heads. [10]
Larvae burrow into the soil to pupate, where they remain for two to three weeks before they emerge as adults. In some sphingids, the pupa has a free proboscis, rather than being fused to the pupal case as is most common in the macrolepidoptera. [2] They have a cremaster at the tip of the abdomen. [5]
As caterpillars, they have a wide range of color phenotypes but show consistent adult coloration. [3] With a wide geographic range throughout Central and North America, H. lineata is known to feed on many different host plants as caterpillars and pollinate a variety of flowers as adults. [4] [5]
T. absoluta was originally described in 1917 by Edward Meyrick as Phthorimaea absoluta, based on individuals collected from Huancayo (Peru). [2]: 240 Later, the pest was reported as Gnorimoschema absoluta, [3] Scrobipalpula absoluta (Povolný), [2]: 240 or Scrobipalpuloides absoluta (Povolný), [2]: 240 but was finally described under the genus Tuta as T. absoluta by Povolný in 1994.< [4] [5 ...

The caterpillars feed on buds, flowers, grains, fruits, pods; sometimes leaves and stems. In cotton they are found on the vegetative part and reproductive structures. In corn, millet at sorghum they attack the grain. In tomato and beans caterpillars bore into young fruits and in chickpea they attack foliage and consume developing seeds. [14]
