Aphids Comments
APHIDS: Characteristics and Controls They feed on buds and flowers, are common on cymbidiums; winged forms can reinfest continually so systemic insecticides which last a month are preferred; use dimethoate (Cygon), Meta-systox and Temik. AH4; use Malathion, N329; in Florida, two kinds named, seven controls listed, DK10+, S190; use Meta-Systox-R, or Zectran, C73-22; OR74-227; OR74-230 0
APHIDS: Control by "lady Bugs" They will not control an infestation. A74-708 0
APHIDS: Control on Cymbidium Flower Buds If black or brown, spray with Malathion 1 to 1.5 tpg. or, with Cygon 2E at 2 tpg.,; or, Lindane liquid concentrate at 1.5 tpg,; if aphids are green Lindane may be best. A72-534 0
APHIDS: Controls A common aerosol insecticide spray is satisfactory; use Raid and stand back several feet from plants to be most effective; don11 use a commercial insect repellant because they damage buds and flowers. RMH; A85-99Malathion, Diazinon, Cygon, Parathions are used for controls in Hawaii. P69(l)-llOrthene WP is recommended. NZ86-194The easiest and least harmful way to clear buds is to rinse them with a mild solution of dish-washer soap (not detergent); a repeat may be necessary. A87-732; spraying on is easier than rinsing. RMHThe ingress of ants into the greenhouse can best be detected by means of sticky cards made of cardboard, etc., a foot square and painted yellow with the surface covered with Stickem, or simi lar adhesive, place them at strategic points and inspect them daily for signs of crawling or flying pests; can be cleaned with turpentine about monthly and used again.
