Kelton plant bug

The Lygus keltoni, commonly known as the Kelton plant bug, is a species of true bug belonging to the Miridae family. Like other members of the genus Lygus, it is recognized as a significant agricultural pest that affects various crops by feeding on their sap and reproductive structures.

The host range of Lygus keltoni is extensive, including legumes, cereals, and numerous horticultural crops. They are particularly attracted to actively growing parts of the plants such as buds, flowers, and developing seeds, where they can cause the most severe physiological damage.

The life cycle of this pest typically follows a hemimetabolous pattern, consisting of eggs, five nymphal instars, and adults. These insects overwinter in sheltered habitats, including crop debris, weed patches, or soil litter, emerging when temperatures rise in early spring to begin their feeding and reproductive cycle.

Feeding damage occurs when the bug pierces plant tissues with its specialized mouthparts, injecting salivary enzymes that cause necrosis, deformation, and stunting. This often leads to flower abscission and significant yield reduction, as the plant redirects energy to repair damaged areas rather than developing fruits or seeds.

Integrated Pest Management (IPM) is crucial for controlling Lygus keltoni. Effective strategies include sanitation, which involves clearing fields of weeds that host the insects during the off-season, and the use of targeted insecticide applications when monitoring indicates that populations have exceeded economic thresholds.
