Biogeography of the phoracanthine beetles (Coleoptera: Cerambycidae)

Six biogeographic subregions of the phoracanthine beetles are proposed on the basis of 136 valid species in all eleven genera of this Australasian group of insects: the Kosciuskan, Western, Eyrean, Torresian, Timorian and New Guinean. Both phenetic and cladistic approaches are employed in the biogeographic study of these beetles. Phenetically, the Kosciuskan and Torresian fauna are the most similar and the least faunal similarity occurs between the New Guinean subregion and all others. Cladistically, two distinct peripheral faunas are divided: the southern Western+Kosciuskan and the northern New Guinean+Torresian+Timorian. The Eyrean fauna in the central Australian continent is more distantly related to the remainder than the latter are to each other. Biogeographic history of the phoracanthine beetles is discussed extensively.     

Mating behavior ofPhytoecia rufiventris Gautier (Coleoptera: Cerambycidae)

Sexual behavior between males and females, as well as between males, is described and discussed for the cerambycid beetlePhytoecia rufiventris. The beetles' taxis toward plants taller than average height brings the sexes together from a distance. A male may mount another individual (male or female) and attempt copulation without sex discrimination. The male can discern the sex of another individual only when the terminal part of his abdomen touches the ventral surface of the fifth visible sternite of the latter. No evidence of a sex pheromone is found in this species. Within 1.5–5.5 cm the substrateborne vibrations produced by a moving individual may be the important factor which elicits males to approach a moving individual and attempt copulation. If a female is receptive when a male touches her, he can copulate with her without any courtship display. However, if the female runs away and appears unreceptive, the male will perform courtship displays. Copulation is usually terminated by males. Homosexual behavior between males is discussed.     

松褐天牛的交配行为

采用室内试验和野外观察相结合的方法,对松材线虫病的主要媒介昆虫松褐天牛Monochamus alternatus Hope的交配行为进行了研究。结果表明： 松褐天牛一次完整的交配包括相遇抱对、插入输精和配后保护3个阶段,在交配过程中雄虫有多次插入输精现象发生。室内试验中共观察到松褐天牛的交配123次,松褐天牛一次完整的交配过程平均需时63.49 min,其中输精前的抱对时间平均为1.68 min,交配过程中每次输精插入时间平均为57.60 s,配后保护时间为15.18 min。松褐天牛在开始交配的4天内平均交配5.15次,不同雄性个体所获得的交配机会差异很大。松褐天牛的交配行为表现出强烈的雄性竞争现象,雄虫能根据雌虫或自身的交配经历调整交配投入,当雌虫或者雄虫是初次交配时,总输精时间和插入输精的次数显著大于与有交配经历的雌虫或雄虫交配时的输精时间和插入输精次数。田间松褐天牛的交配行为与室内观察结果基本一致。

Hispaniolan Hemilophini (Coleoptera,Cerambycidae, Lamiinae)

The Tribe Hemilophini (Lamiinae) is reviewed for Hispaniola and an identification key is provided. Fifteen species are now known from the island, including one new species of Adesmus (Adesmus fortunei from Pedernales and La Vega Provinces, Dominican Republic), one new species of Oedudes (Oedudes anulatus from Peravia and La Vega Provinces, Dominican Republic), and five new species of Calocosmus (Calocosmus contortus from San Cristóbal Province, Calocosmus punctatus from Peravia Province, Calocosmus rawlinsi from Elías Piña Province, Calocosmus robustus from La Vega Province, and Calocosmus thonalmus from La Altagracia Province, all in the Dominican Republic). Oedudes and Adesmus are new island and country records for Hispaniola and Dominican Republic, respectively. Calocosmus holosericeus Gahan is a new synonym of Calocosmus janus Bates. In addition to the new species, five new country records and four new island records are presented for Calocosmus.

Chromosomenzahlen einiger mitteleuropäischer Cerambycidae (Coleoptera)

Zusammenfassung Von 20 Cerambyciden wurden erstmals die Chromosomenzahlen — meist aus Metaphasen in den Spermatocyten — ermittelt und in einer Übersichtstabelle zusammengestellt. Es werden Angaben über den Zeitpunkt des Meiose-Ablaufes und über die untersuchten Stadien gemacht. Schließlich wird kurz auf Gesichtspunkte eingegangen, die sich aus den festgestellten Chromosomenzahlen für die Systematik ergeben.

Toxicity of ethanedinitrile to Anoplophora glabripennis (Coleoptera: Cerambycidae) larvae

The mortality of naked Anoplophora glabripennis Motschulsky (Coleoptera: Cerambycidae) larvae exposed to ethanedinitrile (cyanogen; C2N2) varied with temperature, time of exposure, and dose of ethanedinitrile. The concentration x time (Ct) product of ethanedinitrile over a range of temperatures (4.4, 10.1, 15.6, and 20.1 degrees C) decreased with increasing temperature, for both 3- and 6-h exposures. The Ct products varied with time of exposure at different temperatures. The variations in mortality at different temperatures are described with a slope ratio (Y = [slope]6h/ [slope]3h). At different temperatures, the concentration of ethanedinitrile and the duration of exposure play different roles in killing A. glabripennis larvae. These results suggest the control of A. glabripennis larvae within wood is achievable.
