However, conserving resident natural enemies is a more efficient and longer lasting strategy than buying and releasing beneficials in gardens and landscapes. Honeydew drippings from plants can be efficiently monitored using water-sensitive paper, which is commonly used for monitoring insecticide droplets and calibrating sprayers. Make sure that the ficus is well-watered, as oil can injure plants that are under drought stress. The covers often have a differently colored, slight protuberance (exuviae or nipple) and concentric rings may form as nymphs (immatures) grow and their cover enlarges.

Both sexes pass through three growth stages before sexual maturity. Honeydew monitoring is useful where there is a low tolerance for dripping honeydew, when managing many trees, such as along city streets or in parks, and on tall trees where the honeydew-producing insects may be located too high to easily observe. Publ. Scrape off minor scale infestations with a plastic scraper. Publ. If a large proportion of scales are dead or parasitized by natural enemies, consider delaying a treatment decision and monitor the population again later before deciding whether to apply pesticide. When populations are high, trees appear to be flocked with white specks (Fig. Do not apply systemic insecticides to plants during flowering or shortly before flowering; wait until after plants have completed their seasonal flowering unless the products label directions say otherwise. commitment to diversity. Calif. Agric. This factsheet has not been peer reviewed. If the descending ants have swollen, almost translucent abdomens, they may be feeding on honeydew produced by scales or other insects.
