He leaf miner<\/strong> It is a small fly that lays its eggs inside the leaves; when they hatch, the larvae emerge and create galleries or mines inside the leaves, giving rise to its name.<\/p>\n

High relative humidity conditions are conducive to egg-laying, but, as with other insects, it is the ambient temperature that truly influences population development. Egg-to-adult development can take approximately 25 days at 20\u00b0C and about 15 days at 25\u00b0C.<\/p>\n

Another factor influencing the development of leafminer populations is the cultivated variety. Generally, these insects do not cause significant infestations in indoor cannabis, but they are becoming increasingly common in outdoor and greenhouse crops in subtropical regions.<\/p>\n

\"Insecto<\/center>The larvae are responsible for the damage to plants by creating mines or galleries in the mesophyll of the leaves. The larvae are very active throughout their development, burrowing into the leaves with their chewing mouthparts.<\/p>\n

Typically, leafminer larvae move within the leaf where the egg was laid, but they can migrate through the petiole when a food source is insufficient. The resulting mines destroy the photosynthetic organs of the cannabis plant.<\/p>\n

Adult females also damage the plant, making feeding punctures and leaf punctures. These punctures are perforations made only by adult females on the upper surface of the leaves, while the male does not possess a piercing apparatus.<\/p>\n
