Palos Verdes trees and Boring insects 02
Hello this is Pat with Warner’s tree surgery and today I’ll be talking about Palos Verdes trees and the danger they face from Boring insects.
Insect pests can and do injure the Palos Verdes and other desert trees, these pests can damage leaves, twigs, branches, trunks and roots. The most dangerous is the root borer
The Palos Verdes borers are root borers and are rarely seen above ground, adults are 4 to 6 inches long with antennae nearly as long as their bodies,the adults are active from July through October. Immature larvae feed on the roots of Mexican Palos Verdes and other non-native trees. Lrvae feeding on roots and spend up to three years underground. Over a 7 to 10 year period, the root borers will gradually kill a tree. Most adult female root borers lay eggs from spring through summer.
another class of insects that usually attacks stressed or damaged desert trees like the Palos Verdes are the Flathead borers. Flathead borers usually attack sunburned or damaged areas along the trunk and branches of trees, olive gray adults lay eggs under the bark of damaged areas - the larvae are cream-colored and legless and mature to one and ½ inches long. The maturing larvae feed on deadwood and make small tunnels in what appears to be sawdust, this damage occurs beneath the bark and can go unnoticed for long periods. Another borer that attacks the Palos Verdes is the round headed borers, this is what the larvae of the round headed borers looks like.
Aanother type of insect are insects that attacked the foliage of desert trees, these include Acacia whitefly’s psyllids and aphids Acacia whitefly actually appears dark gray or black because of the large spot on the body these insects reproduce rapidly and cause significant leaf loss. Aphids are a common and widespread plant pest that can attack desert species. Aphids are restricted to the succulent new growth on the tips of the twigs of desert trees, Aphids reproduce rapidly and can quickly kill small twigs and deposit honeydew - a clear sticky material created by the aphids - that blackens leaves and twigs.
Tthis is a psyllids. Psyllids feed by scraping on the undersides of leaves giving the leaves a blotchy yellowing appearanc, psyllids suck plant juices and produce honeydew sometimes and crystallized form on which black sooty mold grows. Abundant psyllid infestation can cause defoliation and reduce plant growth,
