Natural habitats surrounding agricultural Þelds provide a source of natural enemies to assist in pest control. The boundaries among landscape elements Þlter some organisms attempting to cross them, resulting in differing communities within the landscape elements. Ground beetles are numerous and generally disperse by walking. These qualities make them excellent organisms for the study of boundar...

1. The relationships between number of species, abundance per species, and body length are examined for 859 species of beetles in samples of arthropods collected from ten Bornean lowland forest trees by insecticide fogging. Similar relationships are examined for different feeding guilds of these beetles, and for those beetles from different species of

Whirligig beetles (Coleoptera: Gyrinidae) are semi-aquatic insects with a morphology and propulsion system highly adapted to their life at the air-water interface. When swimming on the water surface, beetles are subject to both fluid resistance and wave resistance. The purpose of this study was to analyse swimming speed, leg kinematics and the capillarity waves produced by whirligig beetles on ...

Phenology and abundance of bean leaf beetles, Cerotoma trifurcata (Förster), were examined throughout two eastern South Dakota growing seasons in relation to grain yields in chisel- and ridge-tilled soybeans [Glycine max (L.) Merrill] grown in 2-yr rotation with corn (Zea mays L.) with and without added nitrogen (N). Populations were also sampled early and late season in alfalfa (Medicago sativ...

Fluon PTFE is a fluoropolymer dispersion applied as a surface conditioner to cross-vane panel traps to enhance trap efficiency for cerambycid beetles. We describe the results of three experiments to further optimize cerambycid traps of different designs and to test the effect of Fluon over time. We tested Fluon with Lindgren funnel and panel traps fitted with either wet or dry collection cups o...

this report is part of a national project for gathering and classifying the arthropod seed feeders in different provinces of iran between 2008–2014. in this paper, nineteen host species with their areas of distribution are presented for twelve species of seed beetles (chrysomelidae: bruchinae). most of the identified host plants (84%) belong to the family fabaceae (leguminosae). in addition, al...

Xylem resin-a supersaturation of resin acids in terpenesappears to play a paradoxical role in the relation of the Pinaceae to tree-killing bark beetles. It has been suggested as the agent responsible for the susceptibility of this coniferous family to beetle attacks. And, at the same time, it has been linked with the ability of the Pinaceae to resist bark beetles. The hosts of treekilling bark ...

The objective of this study was to quantify the relationships between heavy metal concentrations in soil, leaf litter, and ground beetles at four sampling sites of a forest ecosystem in Medvednica Nature Park, Croatia. Ground beetles were sampled by pitfall trapping. Specimens were dry-ashed and soil and beetle samples digested with nitric acid. Lead, cadmium, copper, zinc, manganese, and iron ...

Thirteen species of Tenebrionidae are newly reported for New Brunswick, Canada. Paratenetus punctatus Spinola, Pseudocistela brevis (Say), Mycetochara foveata (LeConte), and Xylopinus aenescens LeConte are recorded for the first time from the Maritime provinces. Platydema excavatum (Say) is removed from the faunal list of New Brunswick, and the presence of Platydema americanum Laporte and Brull...

Neomidadiminuta sp. n. is described, based on a single male specimen from Colombia, and a redescription of Neomidasuilla (Champion) is given. Data on the morphology of the aedeagus for both species, and on the female abdominal terminalia for Neomidasuilla are provided. New records of Neomidasuilla from Atlantic Forest remnants in the states of Espírito Santo and Minas Gerais, Brazil are given.
