The Moroccan citrus export season of 2008/09 has been disappointing. Total citrus exports are estimated at 469,150 tons, a decline of 15 percent compared to exports in 2007/08 and about 28 percent below the government’s target for this year. Most of the decline occurred in orange exports. Exports to Russia, the main export market, suffered a sharp decline.
Integrated pest management (IPM) for nematodes requires: 1) determining whether pathogenic nematodes are present within the grove; 2) determining whether nematode population densities are high enough to cause economic loss; and 3) selecting a profitable management option. Attempting to manage nematodes may be unprofitable unless all of the above procedures are carefully followed. Similarly, some management methods pose risk to people and the environment. Therefore it is important to know that their use is justified by the actual conditions in a grove.

2010 Florida Citrus Pest Management Guide: Plant Bugs, Chewing Insect Pests, Caribbean Fruit Fly, and Thrips
Citrus root weevils represent a complex of species known to infest citrus trees and various alternate host plants in Florida. The most common species infesting citrus in order of greatest geographical distribution are the blue-green citrus root weevils, Pachnaeus litus and Pachnaeus opalus, the Diaprepes root weevil, Diaprepes abbreviatus, the little leaf notcher, Artipus floridanus, and the Fuller rose beetle, Asynonychus godmani. Other lesser species inhabit citrus on occasion.
The index of prices received by fruit and tree nut growers fell 9 percent from the March index. Pushing down the index were significant grower price declines for grapefruit and strawberries in April from the previous month. These price declines more than offset price gains for other citrus crops and for fresh-market apples and pears during the month.
This section of the Citrus Pest Management Guide provides information on the group of insects belonging to the order Homoptera which affect foliage, twigs, and fruit of citrus in Florida. The insects covered here include scale insects, mealybugs, whiteflies, and aphids. These insect species affect tree health and fruit quality, and can impact mature fruiting trees as well as newly planted groves and resets. Their biologies, generation times, plant parts affected, and injury vary, but similar approaches to their monitoring and management cause them to be grouped here.
There are four families of phytophagous mites with species that are of economic importance:
