Asian Citrus Psyllid
Asian citrus psyllid (ACP) is an efficient vector of the bacterial citrus disease huanglongbing (HLB), previously called citrus greening disease, which is one of the most destructive diseases of citrus worldwide. ACP nymphs can only surive on the new flush tips of citrus. Because they produce a toxin, the flush tips die back or become twisted and the leaves do not expand normally. The fruit is of no value because of poor size and quality
This problem can be reduced through pesticide control of the psyllid population or releases of natural enemies. Read more from UC Riverside

Citrus Leafminer
Citrus leafminer larvae feed by creating shallow tunnels, referred to as mines, in young leaves. It is most commonly found on citrus (oranges, mandarins, lemons, limes, grapefruit and other varieties) and closely related plants (kumquat and calamondin). The larvae mine the lower or upper surface of the leaves causing them to curl and look distorted. Mature citrus trees (more than 4 years old) generally tolerate leaf damage without any effect on tree growth or fruit yield. Citrus leafminer is likely to cause damage in nurseries and new plantings because the growth of young trees is retarded by leafminer infestations. However, even when infestations of citrus leafminer are heavy on young trees, trees are unlikely to die. Read more from UC IPM Davis
What you can do to monitor the presence of these pests
Citrus Leafminer Traps - ISCA Delta Traps are USDA approved and are one of our most popular and dynamic trapping devices. Use these traps to monitor your grove, orchard, row crops and nursery plants.
They are inexpensive, easy to use, and readily assembled, allowing for rapid deployment and a quick tally of the population estimates.
Diaprepes Root Weevil
This weevil will feed on about 270 different plants including citrus (all varieties), hibiscus, palm, birch, roses, guava, loquat, holly, and other ornamentals. Because of its broad host range, the Diaprepes root weevil poses a great threat to citrus and ornamental plant industries and potentially other crops in California.
The Diaprepes root weevil damages both the leaves and the roots of plants.
