Life cycle assessment (LCA) was applied to evaluate black soldier fly production using different diets, including typical Belgian agro-residues (Brussels sprout stems, endive roots and solid fraction pig manure). The LCA compared insect-based feed with soybean meal fishmeal, composting through insects versus conventional treatments. Underlying data were derived feeding experiments. To determine...

The role of glutathione S-transferase (GST, EC 2.5.1.18) in the degradation of and resistance to some insecticides of diamondback moth (DBM) larvae has been confirmed through the purification and characterization of its four isozymes from this notorious insect pest of cruciferous vegetables. Two immuno-related isozymes, GST-3 and GST-4, exhibit apparent substrate preference for 1,2-dichloro-4ni...

Distribution and movement patterns of several species of stored-product pests in a food processing plant were investigated. The objectives of this study were to determine the temporal and spatial variation in abundance of stored-product pests using pheromone traps; assess the effectiveness of trap type, location, and number on monitoring insect populations; and to evaluate the nature of pheromo...

Balasubramanian, A., Jayas, D.S., Fernando, W.G.D., Li, G. and White, N.D.G. 2007. Sensitivity analysis of DNA fingerprinting technique for detecting insect fragments in wheat flour. Canadian Biosystems Engineering/Le génie des biosystèmes au Canada 49: 4.14.5. Tribolium castaneum (Herbst) and T. confusum (Jaquelin du Val) are the most commonly occurring insect species in flour mills and in dam...

Purpose of review: Tactics to manage infestations of stored-product insects in grain-processing facilities historically included the use of heat treatments and the fumigant methyl bromide. The phase out of methyl bromide in the USA in 2005, because of its adverse effects on stratospheric ozone, has renewed interest in using heat treatments. In this review, a brief history regarding the use of h...

Signaling networks among multiple phytohormones fine-tune plant defense responses to insect herbivore attack. Previously, it was reported that the synergistic combination of ethylene (ET) and jasmonic acid (JA) was required for accumulation of the maize insect resistance1 (mir1) gene product, a cysteine (Cys) proteinase that is a key defensive protein against chewing insect pests in maize (Zea ...

Arginine kinase (adenosine 5'-triphosphate: L-arginine phosphotransferase, EC 2.7.3.3) was purified from the larvae of the tobacco hornworm, Manduca sexta (L). This enzyme catalyzes the production of L-phosphoarginine, which is the principal reserve of high energy phosphate compounds in insect muscle. The enzyme also phosphorylates L-canavanine, a guanidinooxy analogue of arginine which severel...

The major auxin-binding protein (ABP1) from maize (Zea mays L.) has been expressed in insect cells using the baculovirus expression system. The recombinant protein can be readily detected in total insect cell lysates by Coomassie blue staining on sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE). Our data suggest that ABP1 is processed similarly in both insect cells and maize...

1. The conservation of insects is not a priority for most urban dwellers, yet can be accomplished in urban settings by the careful design of urban nature. Our goal is to foster cross-talk between practitioners of insect conservation biology who develop the knowledge base and professional design practitioners who are poised to apply this knowledge in designs and management plans for urban green ...
