HORTICULTURE

Detailed explanation-1: -The larva and pupa are the two different developmental stages of an insect. The larva is called the first or the primary stage of an insect life cycle, later followed by a pupal stage. The larva is a worm-like creature, which emerges from an egg.

Detailed explanation-2: -Larva: the second, “worm-like” stage in the life cycle of insects that undergo complete metamorphosis (like caterpillars).

Detailed explanation-3: -When the immature insects and the adults have different forms, the process is called complete metamorphosis, and the worm, or grub, like juvenile insects are called larvae.

Detailed explanation-4: -Eruciform larvae are caterpillar-like and have a cylindrical body and well-developed thoracic legs, and prolegs are present. Finally, vermiform larvae are “wormlike.” It is generally applied to an elongate, legless larva with or without a conspicuous head.

Detailed explanation-5: -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.
