Chemical Ecology of Clytini (Coleoptera: Cerambycidae)
In chapter six, I characterize the contact sex pheromone of N. a. acuminatus. Males recognize female conspecifics only after contacting them with their antennae. I characterize the behavior and demonstrate that three methylalkanes present in the wax layer of females are sufficient to elicit a …

Host plant associations and chemical ecology of Cerambycidae
… number of longhorned beetle species (Coleoptera: Cerambycidae) are considered major pests worldwide. Longhorned beetles include some of the most damaging pests of woody plants and invasive species pose a serious threat to North American forests. The beetle family of Cerambycidae is a diverse group …

Wood trait preferences of Neotropical xylophagous beetles (Coleoptera: Cerambycidae)
… Panama Canal, trees were felled and exposed to Cerambycidae for oviposition. Disks from branches of differing thickness from the same plant individuals were used to calculate WD, MC, and BT in the field; nitrogen content was determined using mass spectrometry. Thick and thin branches tended to …

Host plant relationships and chemical communication in the cerambycidae
The beetle family Cerambycidae is one of the largest groups of insects. Commonly referred to as longhorned beetles, the larvae of cerambycids usually feed on the tissues of woody plants and can be important insect pests, damaging and even killing trees in managed and natural landscapes. In this …

Revisão da tribo Onocephalini Thomson, 1860 (Insecta, Coleoptera, Cerambycidae, Lamiinae)
The tribe Onocephalini Thomson, 1860, nowadays composed of four genera and twenty-three species, is revised in its totality. The studies were carried out through entomological material from collections of the Museu Nacional, Universidade Federal do Rio de Janeiro, Rio de Janeiro, of the Institut …

Aspects of Hylotrupes bajulus (L.) biology in Virginia (Coleoptera: Cerambycidae)
The significant results of this research were: 1) A laboratory colony of H. bajulus was established and information on the N. A. biotype was collected. At this time it is too early to make any significant statements of comparison between European and N. A. biotypes. However, preliminary results …

Chemically-Mediated Mate Location and Recognition in Longhorned Beetles (Coleoptera: Cerambycidae)
Larvae of many cerambycid species require woody host plants that are stressed or weakened in some way. Such hosts represent an ephemeral and unpredictable resource, with prime subcortical tissues being rapidly degraded by a variety of wood-feeding insects. Thus, the first larvae to colonize a host …

Pheromone chemistry and reproductive isolation in the subfamily Lamiinae (Coleoptera: Cerambycidae)
Research on the chemical ecology of cerambycid beetles has revealed that the pheromone chemistry of related species is often highly conserved. Sympatric species often share pheromone components, even having identical attractant pheromones. For example, many cerambycines native to different …

Sistemática da tribo Platyarthrini Bates, 1870 (Coleoptera, Cerambycidae, Cerambycinae) na região neotropical
The present dissertation deals with Neotropical Platyarthrini. Platyarthron Guérin-Ménéville, 1844 and Stenygra Audinet-Serville, 1834 are revised and illustrated. S. histrio nigrina Franz, 1954 is found to be a chromatic variation of S. histrio Audinet-Serville, 1834, without geographical …

Sistemática e zoogeografia do gênero Tomopterus Audinet-Serville, 1833 (Coleoptera, Cerambycidae, Cerambycinae, Rhinotragini)
The neotropical genus Tomopterus Audinet-Serville, 1833, is revised. Six groups of species, based on comparative study of the external morphology and male terminalia, are proposed: bispeculifer group (T. rufotibialis, T. bispeculifer, T. roppai); basimaculatus group (T. basimaculatus); albopilosus …

Aspects of the morphology of the ovipositor of Hylotrupes bajulus (L.) (Coleoptera: cerambycidae)
Hylotrupes bajulus (L.) is a serious pest of seasoned softwoods. The female oviposits in the cracks and crevices of the wood, and the larvae can survive and feed in the wood for 2-10 years. The female H. bajulus has an elongated ovipositor comprised of the modified abdominal segments 8 and 9, …

Life history studies of the old house borer, Hylotrupes bajulus (L.) (Coleoptera: Cerambycidae)
A North American biotype of the old house borer, Hylotrupes bajulus (L.) was established from field and laboratory data. This biotype is based on differences in size and longevity of the life stages and on adult fecundity. N. A. females were observed to oviposit a mean of 165.1 ± 15.5 eggs in …

Aspects of chemical control of the old house borer, Hylotrupes bajulus (L.) (Coleoptera: Cerambycidae)
The formulation of Dursban®, manufactured by Dow Chemical Corp., and its diluting agent were found to influence the penetration abilities of the final spray when it is applied to pine sapwood. The diluent of choice for providing the best penetration of the active ingredient, chlorpyrifos, is an …

Factors contributing to variation in cuticular hydrocarbon profiles of two species of longhorned beetles (Coleoptera: Cerambycidae)
In many insects, females have certain hydrocarbons in their cuticular hydrocarbon profile that serve as contact pheromones. These sex-specific mate recognition signals are present in much smaller quantities, or even absent in males. Although hydrocarbon profiles are to some degree heritable, the …

The Influence of Chirality on the Behavioral Responses of Longhorned Beetles (Coleoptera: Cerambycidae) to Volatile and Contact Pheromones
In this dissertation, I present research I conducted to test the hypothesis that chirality influences the behavioral resposnses of longhorned beetles to volatile and contact pheromones. Structures of pheromones in the longhorned beetles generally fall along taxonomic lines, and various structural …

There’s more than one way to beat the heat: What anal probes reveal about thermal responses in Neotropical beetles (Coleoptera: Cerambycidae).
<p>Increasing global temperatures have been linked to shifts in the distributions and preferred microhabitats of terrestrial species. This trend is predicted to impact tropical forest insects, which may already be exposed to conditions that bring them close to their thermal maxima. Tropical …
