Beetle Life Cycle ALB and The ALB undergoes a complete metamorphosis.
Diagram by Michael Bohne, Bugwood.org ALB and Beetle Life Cycle The ALB undergoes a complete metamorphosis. Its life cycle consists of four stages: egg, larva, pupa and adult. The ALB undergoes a complete metamorphosis. Mating Asian long-horned beetles begin mating once they have emerged from the pupa stage and become adult beetles. After mating, the male Asian long-horned beetle guards the female against other male beetles in order to ensure that his sperm will fertilize the female's egg. Eggs Female Asian long-horned beetles chew small holes or grooves into the bark of trees. They then lays eggs one at a time into grooves or holes. The eggs are off-white in color, oblong in shape and approximately 1/4 inch in length. The eggs are also concave at either end. After the female beetle has laid her eggs, she covers the hole with digested wood called "frass." Larvae Approximately 11 days after the female beetle lays her eggs, the larvae emerge from the eggs. Asian long-horned beetle larvae measure about 2 inches long. The Asian longhorned beetle larvae feed on the cambium of trees. The larvae molt two times. As they grow, they burrow further into the tree as they eat. The larvae then make a chamber within the tree in order to pupate. Pupae The Asian longhorned beetle pupae are off-white in color. The pupa stage lasts for about 20 days. The pupae are approximately 1 1/4 inches long and 1/2 inch wide. The pupae have a protruding abdominal structure on the eighth body segment. Adults Adult Asian longhorned beetles are shiny black in color with white or yellow spots. They have two long antennae, each with 11 segments. The male beetle's antennae have white bands on them and are almost two times as long as its body. Adult beetles measure about 1/4 to 1/2 inch wide and 3/4 to 1 1/4 inches long. Asian longhorned beetles only live to be about 42 days old. Read more: Asian Longhorned Beetle Life Cycle | eHow.com

Solutions for ALB Awareness of ALB
Education about life-cycle and signs Stricter off-shore inspections and regs Quarantines Removal and chipping of infested trees Imidacloprid insecticide a class of neuro-active insecticides modeled after nicotine. Taken up by the plant roots into the xylem Imidacloprid is taken up by plant roots and diffuses in the plant via the xylem; its systemic properties then rely on insects ingesting the insecticide (e.g., by sucking plant fluids). The products Confidor and Admire are intended for application via irrigation, application to the soil, or on foliage, while Gaucho is intended for use as a seed dressing, applied to the seed before sowing. Seed-applied insecticides are often used to deal with numerous insects, as they are easy to use and comparable in cost to most traditional insecticides used at sowing time. Some also indicate that it might be better for the environment because less chemical is required than for broadcast or banded applications, or at least because less chemical is sprayed in the air. However, some note that the use of seed-applied insecticides at each season implies the chemical is used whether there is need to fight insects or not. Imidacloprid is receiving increased attention as a possible factor in colony collapse disorder, a mysterious condition that causes sudden death of honey bee populations. Mass die-offs of bees threaten pollination of food crops in the USA and Europe. Imidacloprid is the active ingredient in Bayer's Advantage brand flea and tick drops [2]
