What is the common pest responsible for damage to almonds known as the Navel Orangeworm?

The common pest responsible for damage to almonds known as the Navel Orangeworm is indeed Amyelois transitella. This pest specifically targets almonds and can cause significant damage to the crop by feeding on the nuts, leading to premature nut drop and decreased marketability due to feeding holes that allow for pathogen entry.

In contrast, Anarsia lineatella, known as the peach twig borer, primarily affects stone fruits, such as peaches and plums, rather than almond trees specifically. Xylella fastidiosa is a bacterium that affects various plants, including almonds, but it is not specifically known as the Navel Orangeworm. Its effects are generally related to plant diseases rather than direct feeding damage. Pseudococcus viburni, commonly known as the obscure mealybug, is a pest that mainly targets ornamental and fruit crops, but not specifically the almond crop as the Navel Orangeworm does.

Thus, Amyelois transitella is the most relevant pest concerning almond damage, highlighting the importance of pest identification and management in maintaining healthy almond orchards.
