Abstract:

The larvae of some insects arrange themselves in a tight, orderly circle at rest; a behaviour that Vasconcellos-Neto and Jolivet (1988b) first called "cycloalexy". The word was defined by Jolivet and collaborators in 1990 as a defensive behaviour adopted by insect larvae that form a tight circle with the best defended extremity at the periphery, either heads or abdomens. The formation is also associated with coordinated movements to repel threats. The term has steadily gained acceptance and expanded to include insect nymphs, adult insects and even vertebrates. We review reports of cycloalexy a

Abstract:

Cannibalism is a very common phenomenon throughout the animal kingdom. Females of the green dock leaf beetle, Gastrophysa viridula, lay clutches of eggs on the leaves of dock plants (Rumex species). Cannibalism takes the form of larvae eating unhatched conspecific eggs. Both within-clutch and inter-clutch cannibalism were observed. Within-clutch cannibalism was found to be of very limited extent. However, two observations indicated that cannibalism in G. viridula is more important than this finding might suggest. First instar larvae proved to be much more voracious cannibals when given an unli

Abstract:

Wolbachia are bacteria that infect and induce reproductive alterations in a large number of arthropods. The present study was undertaken to improve our understanding of the effects that Wolbachia have on the reproductive biology of the leaf beetle Chelymorpha alternans Boh, in Panama. Two strains of Wolbachia occur in C. alternans, both of which induce some degree of cytoplasmic incompatibility (CI), a reproductive problem occurring when individuals bearing different infection status are mated together resulting in lowered levels of egg fertility. I attempted to localize where Wolbachia occurs

Abstract:

The Quaternary climate has known dramatic global variations oscillating between long glacial and shorter interglacial periods of approximately 100 000 and 20 000 years, respectively with the last succession as an example. During the glacial episodes the continental ice sheet expansion and sea level drop, in turn, have locally disturbed the environment (at least in the northern hemisphere). These climatic and environmental disturbances caused changes in the geographic distributions of animal and plant species. For each species, the changes possibly took the form of demographic events like popul

Abstract:

The interactions between plants and their insect herbivores are one of the main generators of biological diversity. A fundamental process generating this outstanding diversity is diet expansion to novel host plants. During the last four decades scientists accumulated evidence showing that co-adaptation between plants and herbivores is a major process assembling plant-herbivore interactions. However, rescent research suggests that adaptation is not always a prerequisite to generate novel plant-herbivore interactions. Novel associations between plants and insect herbivores may be assembled by ec

BACKGROUND:Within the Coleoptera, the largest order in the animal kingdom, the exclusively herbivorous Chrysomelidae are recognized as one of the most species rich beetle families.

The prominent role of leaf beetles in the insect world, their omnipresence across all terrestrial biomes and their economic importance as common agricultural pest organisms make this family particularly interesting for studying the mechanisms that drive dive

Abstract:

Anredera cordifolia (Basellaceae), Madeira vine, is a perennial, semi- succulent climber native from Paraguay to southern Brazil and northern Argentina. It has a history of weediness and difficulty of control once established. In South Africa Madeira vine has a wide range and distribution with altitudes ranging from 10-1800m above sea level. Described as a transformer species, its sheer weight is capable of breaking branches off trees, causing the potential collapse of forest canopies. Chemical and mechanical control methods are expensive, labour intensive and may provide only temporary relief

Abstract:

Flea beetles (Alticini) are a highly diversified group of leaf beetles (Chrysomelidae) with about 8 000 known species from about 560 genera distributed worldwide except Antarctica. The major life strategy of flea beetles is external feeding on vascular plants, similarly to other leaf beetles. However, studies published during last years revealed existence of numerous different flea beetle genera feeding on mosses. Moss-inhabiting flea beetles are usually highly specialized and share similar morphological characteristics, including flightlessness, compact body shape and modified antennae. Howev

Abstract:

The adult western spotted cucumber beetle (WSCB), Diabrotica undecimpunctata undecimpunctata Mannerheim is considered a major pest of snap beans grown for processing in Western Oregon. Control consists of 1 or 2 insecticide sprays prior to harvest. A commercial semiochemical-based insecticide bait, Adios TIC��, 1.3% carbaryl + 5% buffalo gourd root powder + 0.7% TIC mixture (1,2,4-trimethoxybenzene, indole, and trans-cinnamaldehyde, 1:1:1), was evaluated for the control of WSCB in commercial snap beans. Adios TIC�� did not result in improved WSCB control as reflected by number of beetles and p

Abstract:

碩士<br>國立臺灣大學<br>昆蟲學研究所<br>104<br>The main purpose of this research is to obtain an understanding of species diversity of leaf beetles (Coleoptera: Chrysomelidae) in the different forest environment in Xitou Nature Education Area, and try to estimate the potential of using leaf beetles as bioindicators in forest ecosystems. Four 500 meters transects are set through the plantations (red cypress, Japanese cedar, Moso bamboo, and broad-leaved plantation) and one 500 meters transect are set through the natural broad-leaved forest, and insects are collected by sweeping alone each transect once a mon
