The primary crops affected by this pest are eggplant, tomato, and melon beans. The infestation causes significant damage to the plants, especially during the growing season.
Symptoms of the infestation include a high reproduction rate, with 10 to 20 generations per year. Both adult and nymph stages feed on the underside of leaves, sucking out the sap. Over time, they move upward and outward across the plant. Infected leaves develop yellow and white spots, which can eventually lead to entire plants turning yellow and drying out in severe cases.
Adults tend to reside in cracks in the soil and around the roots of weeds. In early spring, they reproduce in these weed areas and spread through crawling or by being carried by wind and rain. This makes it essential to manage weeds effectively to prevent further infestations.
Control measures are crucial for managing this pest. First, garden hygiene should be maintained by removing and properly disposing of crop residues—either by burning or grinding them. Second, insecticides can be applied as a preventive measure. Options include using products such as 3,000 times diluted solutions of certain agents, 1,000 times diluted solutions, or Nisso 3000. Another option is 0.9% worm solution at a dilution of 1,400 times. Applications should be repeated every 7 days to ensure effectiveness.
In addition to chemical control, monitoring the crops regularly and implementing integrated pest management (IPM) strategies can help reduce long-term reliance on pesticides. Early detection and prompt action are key to preventing widespread damage. By combining cultural practices with targeted treatments, farmers can better protect their crops from this persistent pest.
