HORTICULTURE

Detailed explanation-1: -There are three stages in the life cycle of these insects i.e., egg, nymph, imago (adult) and no pupal stage is there.

Detailed explanation-2: -Gradual metamorphosis is marked by three life stages: egg, nymph, and adult.

Detailed explanation-3: -An instar (/ˈɪnstɑːr/ ( listen), from the Latin īnstar, “form", “likeness") is a developmental stage of arthropods, such as insects, between each moult (ecdysis), until sexual maturity is reached. Arthropods must shed the exoskeleton in order to grow or assume a new form.

Detailed explanation-4: -Larvae undergo metamorphosis, transitioning to benthonic postlarva or juveniles3. Complex morphological and physiological changes occur during the transition between these stages, and morphological differences in the larvae development of gastropods have been reported4, 5, 6.

Detailed explanation-5: -Instar is the name given to the developmental stage of an arthropod between moults. For example, after hatching from the egg and insect is said to be in its first instar. When the insect moults it is then a second instar and so on. Instar can be used for insects undergoing complete and incomplete metamorphosis.
