In which stage does the pine-shoot moth inflict damage?

Adult Stage
Egg Stage
Larval Stage
Pupal Stage

The correct answer is: Larval Stage

The pine-shoot moth primarily inflicts damage during the larval stage. After the eggs hatch, the larvae emerge and begin to feed on the young shoots of pine trees. This feeding behavior is detrimental as it can cause the tips of the shoots to die back, leading to a range of issues for the tree, including stunted growth and even death if the infestation is severe. Understanding that the larvae are responsible for the damage is crucial for pest management practices. Knowing this allows for targeted control measures to be employed during their active feeding period, which is vital for preventing significant infestations. In contrast, while the adult moth and the egg stage are part of the life cycle, they do not cause direct harm to the tree. The pupal stage also does not inflict damage, as it is a period of transformation rather than active feeding.
