This site is protected by reCAPTCHA and the Google These mites are extremely small and semi-transparent; impossible to see without magnification. However, other pests can also cause allergic reactions. When its populations are high, the potato cyst nematode can cause reductions of 80% in yield of susceptible potato varieties. Additionally, it removes a large percentage of organic matter. After a preliminary section on definition of terms, consideration is given to ways in which insects injure plants and crops, particularly annual crops. Aphids are one of the main culprits in this regard, carrying diseases from plant to plant often uncontrollably as numbers multiply. Privacy Policy and They are responsible for two major kinds of damage to growing crops. Effect of Bt crops on pests. However, some types of thrips are capable of living indoors on houseplants year-round. Habitats that provide alternative hosts or preys may also harbor pests, thereby increasing the vulnerability of that habitat and the other organisms that live in it. Control options: Washing, physical removal, bifenthrin, permethrin, resmethrin, insecticidal soap, pyrethrins, disulfoton, imidacloprid, plant oil extracts (at least two to three applications sprayed once every 10 - 14 days are usually necessary). Flowers become streaked or distorted. But scientists suspect ITCs are only one piece of the pest-control puzzle.
