Cerambycid beetles

Acetylenes. Acetylenes have only been reported from cuticular lipids of two insect species to date, the cerambycid beetle Callidiellum rufipenne (9-pentacosyne and 9-heptacosyne Rutledge et al., 2009) and the ant Platythrea punctata (Hartmann et al., 2005). However, acetylenes have been found in several insect pheromones (see The Pherolist, http //www.nysaes. comell.edu/pheronet/). Thus, it is highly likely that more examples will turn up. Overall,...

Recently in 2008, Lacey et al.1 reported a typical example showing the complexity of a multicomponent pheromone. A male-produced aggregation pheromone of the cerambycid beetle Megacyllene caryae contained as... 

Nonacosane and (Z)-9- (A209), (Z)-ll- (A211), and (Z)-12-nonacosene (A210) are parts of the female sex pheromone of the bee A. nigroaenea 5i The alkene A209 is a contact pheromone of male cerambycid beetle M. 

The cerambycid beetle, Monochamus alternates, is a vector of the pine wood nematode, Bursaphelenchus xylophilus. Mortality of pines is caused by the combination of beetles and nematodes. The following 10... 

Metasternal gland secretions from the cerambycid beetle have been found to contain 3-isopentyl-2,5-dimethylpyrazine (principally) and the 3-propyl, 3-butyl, 3-pentyl, and 3-(2 -methylbutyl) analogues as major components in one genus, and as minor components in several other genera (74b).

An interesting example is provided by certain lycid and cerambycid beetles. The lycids are unpalatable to vertebrates, warningly colored, and mimicked by palatable cerambycids. The situation would thus seem to be simply one of Batesian mimicry, but the cerambycids are carnivorous We thus have the unusual situation of the Batesian mimic preying upon its model, thereby ingesting the model s toxin, and presumably in turn becoming toxic - a Mullerian mimic ... 

Methyl 6-methylsalicylate is the trail pheromone of some ants, it is also found in carabid beetle, 6-methylsalicylaldehyde in the defensive secretion of a cerambycid beetle, and 6-methylsalicylic acid is made by some Penicillium moulds. Orsellinic acid and 6-methylsalicylic acid are... 

Field bioassays with adult cerambycid beedes, Neoclytus acuminatus acumi-natus (F.) (Coleoptera Cerambycidae), revealed that males produce a pheromone that attracts both sexes. Male extracts revealed a single major male-specific compound IS, 3>S )-hexanediol. Field trials showed that a racemic blend of IS, 3S) and 2R, 3i )-hexanediols attracted both sexes and that activity was similar to enantiomerically enriched IS, 3S) hexanediol (e.e. 80.2%). However, a blend of all four stereoisomers attracted only a few beetles. ...
