Resource Manual on IPPM in Vegetable World Education Philippines, Inc. 9. Striped Blister Beetle Epicauta vittata Family: Meloidae Plants attacked: Many vegetables Type of damage: Adults feed ravenously on foliage. Remember: This general feeder readily moves from plant to plant. The beetles can be picked off the foliage. However, they contain an oil that can blister the skin if they are accidentally crushed. The larvae of blister beetles are beneficial because they feed on grasshopper eggs in the soil. 10. Wireworms Family: Elateridae Plants attacked: Many vegetables Type of damage: Wireworms feed on seeds and seedlings of corn, bean, and pea. They also cause wilting and often death of the plant. Wireworms feed on the marketable portions of potato, sweet potato, radish, carrot, rutabaga, and turnip. Wireworms also attack the roots of cabbage, cucumber, tomato, onion, watermelon, and other crops thus, reducing vigor or killing the plants. Remember: Some species are more serious in gardens that are recently sodded. Wireworms can be detected with baits (grain or potato) buried underground before planting. 11. Imported Cabbageworm Pieris rapae Family: Pieridae Plants attacked: Cabbage, cauliflower, broccoli, Brussels sprouts, radish, collard, mustard and kale Type of damage: Caterpillars eat leaves producing large irregular holes in leaves and into heads. Cabbageworms stunt the growth of the plants. They cause failure of the heads to form, thus making the 116

Cabbage Looper Trichoplusia ni Family: Noctuidae Plants attacked: Cabbage, cauliflower, broccoli, brussels sprouts, radish, collard, mustard, kale, lettuce, celery, spinach, beet, pea, potatoes, tomato. Type of damage: Same as imported cabbage worm. Remember: Effects of Cabbage loopers are usually more serious in the fall. They should be controlled when they are still small because the large loopers are difficult to control. They crawl in a looping fashion - inchworm. 13. Diamondback Moth Plutella xylostella Plants attacked: Cabbage, cauliflower, broccoli, Brussels sprouts, radish, collard, mustard, kale Type of damage: Larvae eat many small holes on underside of leaves, giving plant a shot-hole appearance. Some feeding does not go entirely through the leaf. 14. Colorado Potato Beetle Leptinotarsa decemlineata, Family: Chrysomelidae Plants attacked: Potato, tomato, eggplant, pepper Type of damage: Adults and larvae feed on leaves and terminals, causing reduced growth or death of the plant. Remember: Damage can be reduced by fall tillage and elimination of culls and volunteer potato plants. Applying 4-6 inches of straw mulch just after hilling will reduce potato beetle damage. 117
