Title:
Population Dynamics of the Citrus Leafminer in Arizona

Citrus Research Report
Abstract:
Citrus leafminer (CLM) was monitored in a five year old block of lemons on the Yuma Mesa for one year. Unlike 2001, no CLM were found in the spring or early fall. From mid-November through mid-December CLM populations were very light ranging from 1 to 4% infested flush. In early January 2003, the CLM population began to increase peaking on 23 January at 68% infested flush. Although 68% appears to be a large infestation, the CLM population was not numerically high since there was not a great deal of fresh flush growth in the grove at that time. Thus, the CLM were concentrated on what little flush was present. Additionally, CLM larvae were tagged and monitored in January and February 2003. Of the 25 CLM larvae tagged, within five weeks only 9 had survived. Most of those killed appeared to have been killed by predators; most likely Yuma spider mite, Eotetranychus yumensis, and to a lesser extent Tydeus spp. Six of the larvae were killed by parasitoids, comprising two species; Cirrophilus coachellae and an unknown species that was damaged and could not be identified.
