    Adults are found more commonly from 80 to m, over rock, sand, gravel or shells, usually at temperatures between 4° and 10°C. Feed mainly on small bottom-living organisms including crustaceans, mollusks, echinoderms, worms and fishes (sand lance, capelin, silver hake, American eels, herring and argentines) (Ref. ).A batch spawner (Ref. ). Dorsal soft rays (total): ; Anal soft rays: 26 - Slim and long body, straight in the back and stomach. Head looks like a triangle from the top. Smooth body without scale, only male has a line of thin scales (around 18) near the origin of the caudal fin.

    We report six new North American records, one new state record, and one rare record of pyraloid moths from southern Florida, together with diagnostic characters for all taxa. We transfer Ennomosia Amsel from Spilomelinae to Glaphyriinae, Cangetta micralis (Hampson) n. comb. from Deuterophysa Warren, and Microthyris lelex (Cramer) n. comb. from Cyclocena by: 1.

      Whatever one's stance on the "demotion" of Pluto from planet to dwarf planet, the controversy has helped to make the public better aware that the solar system is populated with a lot more than the planets, their satellites, and the occasional comet or meteorite. The solar system is scattered with many smaller objects large enough to be tracked and numbered and sometimes named. 56 2. 1 vs I vs 1 vs variability to be reduced in as we replicate samples and as seasonal changes produce greater numbers of arthropods.

The mountain pine beetle, Dendroctonus ponderosae Hopkins (Coleoptera: Curculionidae), outbreak in British Columbia and Alberta, Canada, currently extends over million ha of pine forest.

Symptoms Top of page Trees attacked by the Douglas-fir beetle are killed by a single generation of beetles. The first evidence of infestation is the occurrence of groups of trees with yellowish-green, yellow or red foliage.

The needles on successfully infested trees begin to fade and change colour about 1 year after they have been attacked. Some examples include D. ponderosae and Dendroctonus adjunctus Blandford in the northern and southern ranges of P.

The Douglas-fir beetle appears to occur in two situations: apparently healthy, large-diameter, host stands where isolated, infested dead-tree groups increase to several to a few dozen trees over a few years and then decrease; and in seriously stressed stands such as those suffering from insect defoliation or exposure to fire that did not ruin the phloem tissue.
