In 2020 and 2021, three species of bark beetles (Coleoptera: Curculionidae, Scolytinae) were established on Macedonian pine ( Pinus peuce ) in the region Vihren hut Pirin Mts. Branches, damaged by snow collected studied laboratory conditions. As a result, 24 specimens Ips amitinus reared 81 I. , Crypturgus pusillus Pityogenes chalcographus 2021. The most abundant was with 75.2%, followed P. (21...

The scarab beetles of the subfamily Orphninae (Coleoptera: Scarabaeidae) from Sri Lanka are reviewed. Four species genus Orphnus Macleay, 1819, recorded island: O. bicolor (Fabricius, 1801), parvus (Wiedemann, 1823), mysoriensis Westwood, 1845, and medvedevi sp. nov. Lectotypes designated for three former names. Synonymy detegens Walker, 1859, scitissimus is discussed. Keys, illustrations habit...

Abstract The small hive beetle, Aethina tumida (Coleoptera: Nitidulidae), is an economically important pest of the Western honeybee, Apis mellifera (Hymenoptera: Apidae). We investigated effect rearing environment on cuticular chemical profile adult A. , using hexane to extract hydrocarbons and other compounds from cuticles beetles. Beetles were collected colonies in Australia as well reared si...

First records of two species beetles (Insecta, Coleoptera), namely Pocadius adustus Reitter, 1888 (Nitidulidae) and Byrrhus pustulatus (Forster, 1770) (Byrrhidae) are given for Georgia. In addition, an update on the occurrences Necrobia violacea (Linnaeus, 1758) (Cleridae), Coelostoma orbiculare (Fabricius, 1775) (Hydrophilidae) Lycoperdina succincta 1767) (Endomychidae) also presented based sp...

In 2006, we examined the flight responses of 43 species of longhorn beetles (Coleoptera: Cerambycidae) to multiple-funnel traps baited with binary lure blends of (1) ipsenol + ipsdienol, (2) ethanol + alpha-pinene, and a quaternary lure blend of (3) ipsenol + ipsdienol + ethanol + alpha-pinene in the southeastern United States. In addition, we monitored responses of Buprestidae, Elateridae, and...

The Japanese beetle, Popillia japonica Newman (Coleoptera: Scarabaeidae), is a serious pest of many agricultural and horticultural plants. Relatively little research has investigated the distributions of Japanese beetles in agricultural fields, and this lack of information makes pest management more difficult. In the present study, the spatial distribution of Japanese beetles in soybean fields ...

In 2 consecutive years, ground beetles (Coleoptera: Carabidae) were sampled in commercial organic and conventional potato fields, using pit fall traps. Four conventional and 3 organic potato fields were surveyed to determine ground beetle taxa composition. In a related study, potato fields were assigned to 1 of 4 transitional systems to include: organic, no spray (usually referred to as no cont...

The coexistence of ecologically similar species (i.e. species utilizing the same resource) is a major topic in ecology. Communities are assembled either through the biotic interactions of ecologically similar species, e.g. competition, or by the abiotic separation of species along gradients of environmental conditions. Here, we investigated the temporal segregation, succession and seasonality o...

The ecological impacts of invasive mammals are widely documented around the world. In New Zealand, fencing designed to exclude non-native is used for conservation and restoration efforts. Orokonui Ecosanctuary a 307-hectare coastal Otago reserve (Dunedin, Zealand) that surrounded by mammal-exclusion fencing. goal present study was investigate how excluding including (native) animals inside fenc...
