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.

A second species of the genus Kochogaster Kamiński et Raś (K. gerardi sp. n.) is described from the surroundings of Garissa (Kenya). The taxonomic concept and phylogenetic relationships of Kochogaster are discussed. A distributional map is presented with complete faunistic data on the genus. Additionally, the original spelling of the name Anchophthalmus inuelleri Schimrosczyk, 2010 is emended t...

We carried out a quantitative assessment of the consumption of herbaceous plants by Opatrumsabulosum (Linnaeus, 1761) - a highly significant agricultural pest species. We researched the feeding preferences of this pest species with respect to 33 uncultivated and 22 cultivated plant species. This species of darkling beetle feeds on many uncultivated plant species, including those with hairy leav...

The orientation stimuli of adult individuals of the beetle Phalerisida maculata Kulzer (Coleoptera, Tenebrionidae) over the beach surface, were studied at two sandy beaches of the chilean coast approximately 1300 km apart, Apolillado (ca. 29 degrees S) and Playa Universitaria de Mehuín (ca. 39 degrees S). Phalerisida maculata did not orient by astronomic cues such as the sun and moon, nor by th...

Ingesting nutritionally imbalanced food can cause a significant reduction in fitness in insects. Insects can avoid the negative consequences of nutritional imbalances by selectively foraging for nutritionally complementary foods. We investigated the ability of the omnivorous beetle, Tenebrio molitor (Coleoptera: Tenebrionidae), to redress nutritional imbalances by selecting complementary foods....

BACKGROUND AND AIMS Several families of tropical plants have thermogenic flowers that show a 2-d protogynous sequence. Most are pollinated by large beetles that remain for the entire period in the flowers, where they compete for mates and feed. Active beetles require high body temperatures that they can achieve endogenously at great energy expense or attain passively and cheaply in a warm envir...

Tocompare resistance to small hive beetles (Coleoptera:Nitidulidae)betweenRussian and commercial Italian honey bees (Hymenoptera: Apidae), the numbers of invading beetles, their population levels through timeand small hivebeetle reproduction inside the coloniesweremonitored. We found that the genotype of queens introduced into nucleus colonies had no immediate effect on small hive beetle invasi...

Knowledge of the population fluctuation and spatial distribution of pests is fundamental for establishing an appropriate control method. The population fluctuation and spatial distribution of the Alphitobius diaperinus in a poultry house in Cascavel, in the state of Parana, Brazil, was studied between October, 2001 and October 2002. Larvae and adults of the lesser mealworm were sampled weekly u...

Two new species of the genus Uloma Dejean, 1821, Uloma fengyangensis sp. n. and Uloma acrodonta sp. n., are described and figured from Zhejiang Province of China. Uloma bonzica Marseul, 1876 is recorded from China for the first time. A key to the known Uloma species from Zhejiang of China and a list of Uloma species from China are provided.
