In May, once the crawlers have settled they will start to produce the distinctive wax covering. This covering protects the insect from contact insecticides like a shield. For the next 6 to 8 weeks the insect will grow and the wax shield will grow with the insect much like the top of an oyster shell. In July the males will grow wings and crawl or fly to mate with females and then die. The second generation of eggs hatches during Mid July during a period lasting up to three weeks. This generation will mature and be full grown by September. The eggs from this mating period will over winter under the wax covering until the spring. The second generation applications will require at least 2 applications. Our Tree Service inspects for crawlers and makes applications at the right time to ensure the most efficacy.
Damage is caused when the Pine Needle Scale inserts its mouth parts into the foliage and sucks out the vital fluids of the plant. This causes yellowing, reduced plant vigor, needle drop and possibly death of the twig and branch during severe outbreaks.
Beneficial insects include 2 varieties of Lady Bird Beetles and parasitoid wasps. The Lady bird larvae are voracious feeders of scale crawlers and the adults continue to feed on the scale insects. It is easy to identify the helpful beetles and choose an organic approach. The wasps on the other hand are very small, very fast and hard to identify without magnification.
Sun Lawn Tree & Shrub offers Plant Health Care programs for one tree to entire landscapes. Our tree service philosophy is to offer organic applications of dormant oil, insecticidal soaps and beneficial insects first by addressing any insect problems early before the need for conventional insecticides. When needed our tree service will apply insecticides with the most "bee and bay" friendly choices first.
Our tree service is licensed and insured and provides service to the Eastern Shore of Maryland, Anne Arundel County and Delaware. Call for an appointment with Bob, a Certified Arborist and Certified Professional Horticulturist to discuss your trees and landscape plants. 1-866-SUN-LAWN
