Citrus long-horned beetle

It affects about 100 different deciduous trees, mainly citrus plants. He is considered the tree pest infested trees are severely damaged or die. Citrus longhorn beetle is shiny black with irregular bright spots on the wing covers, it is about 21 to 37 mm in size, the males slightly larger than females. These sensors are long - in men about two times the length of the body - and black-and-blue stripes. Pronotum has two bright spots. Larvae are legless and white to cream for a length of 60 mm and a thickness of 10 mm. Prothorax has a brownish drawing. Egg resembles grains of rice. It is 5-6 mm long and creamy. Before hatching, it gets yellowish brown color. Within one to three weeks slid by 5 mm wide and the young larva eats first sip under the bark. Then irregular larval galleries are consumed in a bundle that approximately 1.5 - to 2 cm in diameter. Courses go deep into the wood, leading to interrupt the stream of juice and reduce the strength of wood. After a development time of about one to two years (depending on climate conditions), the larvae pupate inside the roots or buttresses. Pupal stage lasts from four to six weeks. Hatching beetle, it begins a new cycle of life. The life cycle of the beetles is from 12 to 24 months. The beetles hatch from April to August, in Italy since the beginning of June to August. The beetles bore their way out of the ground or shallow roots, buttresses and the base of the stem shock tree. Shortly after the start feeding on leaves, stems and bark twigs. The beetles live for two months, they are mostly active during the day. About ten days after hatching their own, after fertilization, the female lays up to 200 eggs up. For this purpose, the pieces of buttress to bark, ground roots and the base of the stem with the slot rostrum T-shaped or a small funnel. In that eggs are placed in each case. Temperatures below 20 ° C, thus reducing the number of eggs.
