Which of the following is a pest with Holometabolous development?

The cigarette beetle is indeed a pest that undergoes holometabolous development, which is characterized by four distinct life stages: egg, larva, pupa, and adult. This type of development is significant in entomology, as it allows for a complete transformation between life stages, enabling the organism to occupy different ecological niches at different points in its life. In the case of the cigarette beetle, the larvae often feed on tobacco and can cause damage to stored products, making them an important pest in agricultural and storage contexts.

In contrast, the other options represent insects with different developmental processes. The damselfly nymph, for instance, exhibits hemimetabolous development, which includes three stages (egg, nymph, and adult) without a pupal stage. Similarly, the damsel bug also undergoes hemimetabolous development, lacking a transformative pupal stage. The crane fly, while it may seem distinct, still follows this same pattern of incomplete metamorphosis, where the larval stage is quite different from the adult stage but does not include a pupal phase. Thus, understanding the life cycle is essential in identifying insects and their potential impact on agriculture and pest management.
