What is the Asian Longhorned Beetle’s life cycle?
The Asian longhorned beetle’s life cycle mostly occurs under the host tree’s bark, so homeowners will not see the egg, larva, or pupal stage. However, once they have matured into adults, their presence becomes known since adult beetles exit infested host trees by chewing holes in the tree and emerging.
How many eggs does an Asian long horned beetle lay?
Egg-laying site chewed by the female Asian long-horned beetle. Adult females lay 45–62 eggs in their lifetime by chewing a small pit through the bark of the host tree to the cambium and lay one 5–7 mm (0.20–0.28 in) long egg underneath the bark in each pit. Eggs hatch in 13–54 days depending on temperature.

How does the Asian longhorned beetle reproduce?
The egg is laid by the female Asian longhorned beetle in a notch that she chews into the bark of a tree. After burrowing, the female beetle then lays a single egg. One female will lay eggs at multiple sites, with the possibility of a single beetle laying up to 100 eggs.
Do Asian longhorned beetles lay eggs?
They lay an egg—about the size of a rice grain—under the bark at each site. (Females can lay up to 90 eggs in their lifetime.) Within 2 weeks, the egg hatches, and the white larva bores into the tree, feeding on the living tissue that carries nutrients and the layer responsible for new growth under the bark.

What insecticides are used to kill beetles?
Insecticides such as imidacloprid, clothianidin, dinotefuran have been used to target adult beetles in canopies or as trunk injections to target larvae. Insecticides within the tree may not translocate evenly, which allows some A. glabripennis to survive treatments.

Larvae expel frass from their tunnels near the original oviposition site. A larva can consume up to 1,000 cubic cm of wood in its lifetime. Asian long-horned beetle larvae do not pupate before they reach a critical weight, so additional larval instars can occur.

How does A. glabripennis reproduce?
When a male contacted a female with his antennae, he generally would quickly attempt to mount her and mate. If the female was receptive (did not fight the mounting and allowed access to her genital chamber), he would mate with her immediately after mounting and initiate a prolonged pair-bond. Non-receptive females would exhibit one or more of the following behaviors: run away, kick with hind legs, hit with antennae, make quick turns, fall, or fly. In these cases, the male might abandon his attempt and separate or perform a short antennal wagging courtship behavior. During the entire time, the male continuously grasped the female with his front tarsi or both front and middle tarsi. During 6 hour observations, individual copulation events lasted an average of 2.8 minutes and 1-10 copulations occurred per event, followed by a male refractory period averaging 95 and 60 minutes, for the New York and Illinois males respectively. During copulations the female remained stationary, walked or chewed the host for oviposition (the latter occurred more often during later copulation events). Between copulations, the female most often walked or attempted oviposition in the pit she had chewed. The average total time in copula during the 6 hours was 34 minutes and this resulted in an average hatch of 56% of eggs females laid over their lifetime. Oviposition (0-5 eggs per female) lasted an average of 12 and 10 minutes, for the New York and Illinois females respectively on bolts with bark 1-2 mm thick. After a female chewed a pit, she rotated 180°, extended her ovipositor, and used it to find the pit. She then inserted her ovipositor under the bark and used the sclerites at the tip of her abdomen to pry the bark up while lifting her body. After laying an egg, she wiped excretions across the opening using the tip of her abdomen. Females abandoned some pits at various points in the process. Females that had been in pair-bond a long time would often begin to exhibit the non-receptive behaviors again usually just after cleaning their antennae. Male usually responded by wagging their antennae to try and calm the female but if this failed they would dismount if the female did not successfully dislodge them first.
Why is it important to know the mating behavior of Anoplophora glabripennis?
There is a critical need for information on the mating behavior of Anoplophora glabripennis (ALB) to provide the biological basis for predicting population dynamics, especially as the population size declines due to eradication efforts. In addition, efforts are continuing to try and develop a trapping system for the adults. Understanding the reproductive behaviors of ALB may also aid in identifying its pheromones and developing a trapping system for early detection and confirmation of eradication.
What is the Asian longhorned beetle?
The Asian longhorned beetle, or ALB, is an invasive insect that feeds on a wide variety of trees in the United States, eventually killing them. The beetle is native to China and the Korean Peninsula and is in the wood-boring beetle family Cerambycidae. Adult beetles are large, distinctive-looking insects measuring 1 to 1.5 inches in length with long antennae. Their bodies are black with small white spots, and their antennae are banded in black and white. Checking your trees regularly for this insect and looking for the damage it causes and reporting any sightings can help prevent the spread of the beetle.
When do aLBs lay eggs?
This results in their feeding, mating, and laying eggs throughout the summer and fall. While adult beetle activity is most obvious during the summer and early fall, adults have been seen from April to December.
How many eggs can an ALB lay?
They lay an egg—about the size of a rice grain—under the bark at each site. (Females can lay up to 90 eggs in their lifetime.)
Where do sawdust beetles burrow?
Sawdust-like material, called frass, from the insect’s burrowing can be found at the trunk and branch bases of infested trees. Over the course of a year, beetle larvae develop into adults. The pupal stage lasts 13 to 24 days.
