Fuller’s Rose beetle (Naupactus cervinus) are 8-9mm in length. the head, antennae, thorax and fused elytra are grey-brown with a pair of light brown stripes on the sides of the pronotum and a pair of oblique white stripes on the side of the elytra. The rostrum is short and conical, with protruding oval black eyes and medium-length antennae. A parthenogenetic species, presenting only one generation per season, they lay the eggs in masses adhered with secretions from the female. Eggs are yellowish in color and are laid in masses. The apodous C-shaped larvae are white, then yellowish, and finally beige. The pupae are cream-colored and have free appendages.
Damage
Adults feed on the foliage, producing notches in the leaves, which in young plants can decrease photosynthetic efficiency, delaying crop development. The most important damage is caused by the larvae, which, by feeding on the root system, impair the absorption of water and nutrients, decreasing production. There are also indirect damages associated with the presence of eggs, for example under the calyx of citrus fruit, which can make the fruits and vegetables unmarketable.
There are specific natural enemies for beetles.
