Coffee bee hawkmoth

The Cephonodes picus, commonly referred to as the coffee bee hawkmoth, is a species of moth belonging to the Sphingidae family of the order Lepidoptera. It is recognized as a notable herbivorous pest that impacts various tropical shrubs, causing economic damage to commercial coffee plantations and ornamental gardens.

Its primary host plants include members of the Rubiaceae family, with Coffea species being the most significant in terms of agricultural impact. Furthermore, the moth has been recorded on various species of Gardenia, Randia, and other related plants, allowing it to maintain stable populations in both wild and cultivated landscapes.

The biological cycle of the insect consists of four distinct stages: egg, larva, pupa, and adult. The larval stage is the most destructive phase, characterized by voracious feeding on leaf tissues. The pupation typically occurs within the soil, where the insect remains protected until the emergence of the adult hawkmoth, which exhibits a distinctive bee-like appearance as an evolutionary defense mechanism.

The damage caused by the larvae is primarily focused on the foliage. Intense grazing results in large, irregular holes in leaves, or in cases of severe infestation, complete defoliation of the branches. This loss of photosynthetic tissue severely limits the plant's ability to produce energy, ultimately reducing the quantity and quality of the coffee harvest.

Effective management strategies for this pest require an integrated approach. Cultural practices such as maintaining healthy soil conditions and clearing weeds around the base of the trees are essential. For chemical control, selective insecticides should be applied during the early larval instars to minimize the damage and prevent the moth from reaching maturity and laying further eggs.
