Locust Borer Beetles are black and hairy. Thin yellow stripes cross the head and thorax. Sometimes two small yellow dots are visible on the 'waist' if the beetle is hunched over. More bands cross its wing coverings, with a large 'W' shaped one being the most obvious. Two more small yellow dots sit near the mid-line of the body. Exceptions include the old‐house borer, Hylotrupes bajulus, which utilizes dead wood (Reddy et al., a,b, ), and P. californicus, which appears to be unique in its use of a pheromone gland on the ovipositor (Barbour et al., ; Cervantes et al., ).
caryae (Gahan), and the locust borer, Megacyllene robiniae (Forster), and one species in the subfamily Lamiinae, the cottonwood borer, Plectrodera scalator (F.). contact, evidence of contact pheromones. These bioassays were conducted during late afternoon and evening (for nocturnal species) or . Woodpeckers feed on the ash borer larvae. They feed high on the tree where the emerald ash borers prefer to feed first. Mature larvae make D-shaped holes about 1/8 inch in diameter when they emerge from the tree as an adult. Emerald Ash Borer Treatment Options. Emerald ash borer traps are available and can trap bugs that are flying to invade.
Megacyllene robiniae, commonly known as the locust borer, is a species of longhorn beetle endemic to eastern North America. It is a serious pest of Robinia pseudoacacia, the black locust tree, with which it is sympatric Boston: Houghton Mifflin Books. pp. – After all those caveats, the book is still definitely worth reading. Pheromones is a relatively unknown science and a reader should be grateful for anything they can get. The amount of information is great, and it makes a strong case for unconscious (undetectable) smells being a major lubricant of human interactions (especially sexuality).Reviews: 3.

Evidence for a pheromone in the locust borer. Upper Darby, Pa.: Dept. of Agriculture, Forest Service, Northeastern Forest Experiment Station, (OCoLC) Laboratory studies have suggested the existence of a pheromone in the locust borer.
Male beetles spent more time on bolts of wood exposed to virgin females than on control bolts. The females apparently deposited the pheromone on the bolts of wood and filter paper. Citation: Galford, Jimmy R.
Evidence for a pheromone in the locust by: Description Male locust borers, Megacyllene robiniae (Forster), responded to females only after contacting them with their antennae, indicating that mate recognition was mediated by a contact sex pheromone.
GC-MS analyses of whole-body extracts of males and females determined that the profiles of compounds in the extracts were qualitatively similar, but differed considerably in the ratios of. In book: Encyclopedia of Entomology, pp Evidence for a pheromone in the locust borer.
U.S. Forest Service Research Note NE The attack rate of locust borers, Megacyllene. (Z)pentacosene, for example, is a component present in the wax layer of the locust borer, Megacyllene robiniae, and acts as a contact sex pheromone .
The locust borer, Megacyllene robiniae Forster inflicts severe damage upon its host, the black locust tree, Robinia pseudoacacia L. Damage is encountered as the larva develops, tunneling first in sapwood and then in heartwood, in the host. The locust borer is monophagous, capable of developing on only one host, the black locust tree.
Whereas the usual habit of longhorned beetles is to enter. Pheromone glands were discovered in the prothorax of male Hylotrupes bajulus (L.) (Coleoptera: Cerambycidae). These exocrine glands were investigated by SEM and light microscopy. Almost the entire prothorax is internally lined with a glandular matrix composed of.

The larval stage (borer) damages plants by destroying internal plant tissue as they feed. More control information on specific species of borers like European corn borers, iris borers and squash vine borers can be found below.

Brodie, Jacob D. Wickham, Stephen A. Teale. The locust borer is a whitish, elongate, so-called "round headed" grub or larva (fig. 1), which hatches from an egg (fig. 2) deposited by a black or brown and yellow striped long- horned winged beetle (fig.
3) found on the trees and on the flow- ers of golden-rod from August to Octo- ber. Clear-wing borer larvae crawl on the bark searching for entry points, which exposes them to insecticide residues.
* Pheromone traps are commercially available for capturing adult males (Figure 3), which helps to determine when females will be laying eggs. Pheromone traps help in timing insecticide applications.
Male locust borers,Megacyllene robiniae (Förster), responded to females only after contacting them with their antennae, indicating that mate recognition was mediated by a contact sex pheromone.
GC-MS analyses of whole-body extracts of males and females determined that the profiles of compounds in the extracts were qualitatively simi. Each of the above pheromones (depicted in Fig. 1) will be discussed in the remainder of the paper in terms of (1) the evidence for the pheromone, (2) isolation and source of pheromone, (3) identification of chemical structure, (4) sensory perception, and (5) ecological and evolutionary aspects.
In mating assays, (Z)pentacosene elicited arrestment, alignment, and mounting, but not copulation, by male beetles. These results represent the first evidence of a contact sex pheromone in a scarab beetle. Such contact pheromones may be an essential, cryptic mechanism for arthropods associated with eusocial insects.
For most desert locust pheromones, site of production and control mechanisms are not known. Vacuolated cells in the epidermis of adult mature male S. gregaria have been described in some detail (see review by Loher, ) and they are thought to be the source of the maturation‐accelerating pheromone (Loher, ).
Instead, the human pheromones act over a period of weeks or months to alter the timing of women’s menstrual cycles.” Around the same time, Cutler established the Athena Institute and, a few years later, she created two trademarked pheromone products, Athena Pheromone for women and Athena Pheromone 10X for men.

Locust borer larvae weaken trees, rendering them susceptible to wind breakage and retarding growth. Severe infestations of locust borer result in many dead and broken limbs, along with swollen areas on the tree trunks.
In some cases, wet spots appear on the bark in early spring, about the time of bud swell–the result of young larvae tunneling. A newly identified chemical sex attractant, or pheromone, of the emerald ash borer could mean improved traps for monitoring and controlling the tree-killing beetle.
The locust borer, M. robiniae, represented by a single specimen, was very common in the region (e.g., Ray et al. ), but was not attracted by any of the pheromones that were tested, and apparently is unlikely to be intercepted by panel traps in forested habitats.
The pheromone for this species is not yet known.
