What are the pests that attack citrus trees?
Biological controls can be an effective treatment for scales on outdoor citrus trees. Natural enemies of the pests include vedalia beetles ( Rodolia cardinal is), adult Australian lady beetles (Rhyzobius lophanthae), twicestabbed lady beetles (Chilocorus orbus) and parasitic flies (Cryptochaetum iceryae). Beetles attack all stages of scale. The larvae feed on scale eggs, and the adults attach themselves to egg sacs and hatch underneath scales. Parasitic flies also feed on the body of scales and hatch eggs inside the scale bodies. They also use the remains of scales during pupation. Vedalia beetles and parasitic flies live in coastal areas and prey on cottony cushion scale. Twicestabbed lady beetles and Australian lady beetles attack brown soft scale.

How do citricola scales grow?
They settle primarily on the underside of leaves, but in severe infestations they also settle on the upper leaf surface and on twigs, rarely on fruit. Young scales are flat and almost translucent; they grow slowly over the course of the summer and fall, molting only once during that period. By November, second-instar scales turn a mottled dark brown color and begin migrating to twigs; this migration peaks in February and March. Once on twigs, they develop faster than they did on leaves and they turn a gray color. By late April, citricola scales molt and mature into the adult female stage. Females lay 1,000 to 1,500 eggs during the time from early May to early August. Eggs hatch after 2 to 3 days and crawlers move to leaves. There is only one generation a year, and there are no males.
How many generations of citricola scale are there?
Brown soft scale has multiple generations and all stages will be present on leaves and twigs year round, whereas citricola scale has only one generation and is found on leaves only in the summer and fall, and the nymphs will be uniform in size.

What parasites control Citricola scale?
Citricola scale is completely controlled by Metaphycus and Coccophagus parasites in Southern California and is almost never seen. Even though these parasites are established in the San Joaquin Valley, biological control is not effective there, and insecticide applications may be necessary in groves where broad-spectrum pesticides are not regularly used to control other pests. In groves practicing biologically based pest management (e.g., releasing Aphytis melinus for California red scale control), growers may consider withholding broad-spectrum citricola sprays until Aphytis activity is over in the fall (e.g., late October or November).
How to determine if a tree has sooty mold?
Examine one 24-inch twig on the northeast side of 10 trees in each of four rows (for a total of 40 twigs) distributed throughout the orchard. On each twig count the number of scales and determine the average number of scales by dividing the total number in the sample by 40. If there is more than an average of one scale per twig and heavy production of sooty mold is occurring, the orchard may require an immediate pesticide application. If the population on twigs or leaves is observable but sooty mold is not a problem, then it is best to postpone pesticide application until fall when scales are small, positioned on leaves on the outside of the tree, and generally easier to control.
Is brown scale the same as citricola scale?

Why do you need a tape barrier on citrus trees?
