- Hang eco-CLM traps to capture males and reduce population levels.
- Spray new growth with eco-oil ensuring good coverage (top and bottom of leaves).

What is the biology of pinned citrus leafminer?
Pinned adult citrus leafminer, Phyllocnistis citrella Stainton, (4mm wingspread). The biology of CLM has been reported by a number of researchers, including Badawy (1967), Beattie (1989), Clausen (1927, 1931, 1933), Fletcher (1920), Kalshoven (1981), and Latif and Yunus (1951). Eggs of CLM are laid singly on the underside of host leaves.
What is the difference between peelminer and leafminer larvae?
The larvae form serpentine mines in the leaves ( Figure 3) and rarely fruit of their hosts. These mines are filled with a central line of frass. This characteristic helps separate this leafminer from the citrus peelminer. The citrus leafminer larvae only infest the younger, flushing foliage.
How many leafminers are in a leaf?
Usually only one leaf mine is present per leaf but heavy infestations may have two or three mines per leaf, and up to nine mines on large leaves have been found in Florida. As with similar leafminers, larvae are protected within the leaf during their feeding cycle.
How do you identify CLM larva?
CLM is most easily detected by its meandering serpentine larval mine, usually on the ventral side of the leaf. Larvae are minute (up to 3 mm), translucent greenish-yellow, and located inside the leaf mine. The pupa characteristically is in a pupal cell at the leaf margin.
