Introduction Associations between bark beetles (Coleoptera: Curculionidae: Scolytinae, or family Scolytidae, depending on the classification used, Bright 1993; Marvaldi et al. 2002) and fungi are varied and well known, but mycophagy (fungal feeding) by bark beetles has received relatively little attention. This may be due to the rarity or relative unimportance of fungal feeding by bark beetles,...

Hermetic storage is used to protect grain against insect pests, but its utility is not limited to whole grains. We evaluated hermetically-sealed, polyethylene terephthalate (PET) bottles for preserving wheat and maize flour against red flour beetle (RFB, Tribolium castaneum, Herbst) population growth. Flours infested with RFB and kept in sealed PET bottles experienced much less weight loss over...

Long-term efficacy of the protein-enriched flour of pea (Pisum sativum L. var. Bonneville) in its toxicity, progeny reduction and organoleptic properties was evaluated by combining it with wheat flour and testing the admixture against the red flour beetle, Tribolium castaneum (Herbst). The toxicity and progeny-reducing effects of the wheat flour treated with protein-enriched pea flour were stab...

The effect of alfalfa seed flour supplementation on the quality characteristics of refined wheat flour-based biscuits was studied. The proximate composition of refined wheat flour and alfalfa seed flour was determined. Refined wheat flour contained 12.43% moisture, 11.52% crude protein, 1.61% crude fat, 0.71% crude fiber, 1.43% ash and 70.83% nitrogen free extract, while alfalfa seed flour cont...

The overabundance of large herbivores is now recognized as a serious ecological problem. However, the resulting ecological consequences remain poorly understood. The ecological effects of an increase in sika deer, Cervus nippon Temminck (Cervidae), on three insect groups of beetles was investigated: ground beetles (Carabidae), carrion beetles (Silphidae), and dung beetles (Scarabaeidae and Geot...

The aim of this research was to study the effect of fortified pan bread with Lupine flour (5, 10 and 15 %) on the chemical, rheological and nutritional properties. Lupine flour showed higher levels of crude protein, ash, crude fat and fiber than the wheat flour. Conversely, wheat flour showed higher contents in carbohydrates. Rheological studies of dough showed clear differences between wheat f...

Grains of the wheat variety Tajan were milled into straight-run flour and bran. Proximate analysis, farinograph experiments and rheological characteristics were conducted. Two types of bran (hydrothermal treated and untreated) at three levels (0%, 5%, 10%) were added to the parent flour. Proximate analysis and farinograph experiments of these flours were conducted. The effects of adding treated...

Accepted: 29/09/2014 Abstract The objective of this work was to investigate the chemical composition, pasting properties and selected functional properties of chickpea and dried green pea flour. The proximate analysis showed that there was a non significant difference in chickpea flour and dried green pea flour composition, except that of crude fat and fiber. The crude fat of chickpea flour sho...

The workplace environment affects the health of workers. Unhygienic conditions are observed in the workplace environment of flour mills as fine organic flour dust gets airborne in the indoor environment of the flour mills. The present work was undertaken to study the health problems related to the workplace environment of flour mill workers. The results show that flour mill workers are receivin...

The first detailed specimen records are presented for the Australian beetle Homotrysismacleayi (Borchmann, 1909) in New Zealand. Evaluation of this evidence clearly indicates that the species is fully established in the wild in New Zealand. It is therefore recommended that the species be added to the New Zealand Organisms Register (NZOR), as exotic and present in the wild. Some general comments...
