Entomologia Experimentalis et Applicata, EarlyView.Spodoptera litura neonates showed increased movement on Bt‐expressing Bollgard 3 (BG) cotton leaf discs but did not initially avoid it. Survival was higher when larvae could move from BG3 to non‐Bt leaf discs. On whole plants, more larvae dispersed from hatching on BG3 cotton compared to non‐Bt cotton. These findings suggest the larval movement differs

Ecological Entomology, EarlyView.Hamiltonella defensa infection increases honeydew production in certain aphid genotypes, potentially modifying aphid feeding behaviour. Parasitoid wasps, Aphidius ervi, are more attracted to honeydew from H. defensa‐infected aphids; though larger honeydew amounts may slightly deter searching.

Cedrela odorata L. PRODUCTION IN A RAW SAWDUST SUBSTRATE IN TECHNICIAN SYSTEM AT TECPAN DE GALEANA, GUERRERO, MEXICO [PDF]
Ra Ximhai, 2011 Nursery high quality plants production by using expensive commercial substrates (peat moss, perlite, vermiculite) decreases profits; this is the main reason to search alternative production substrates.

Medical and Veterinary Entomology, EarlyView.Mortality for diatomaceous earth was observed as early as 2 h after exposure with 50% and 90% mortality at 3.5 and 4.6 h (LT50 and LT90, respectively) for Musca domestica. The LT50 and LT90 increased when the size of the fly species increased (M. domestica to Cochliomyia macellaria to Sarcophaga bullata) and increased for all three from 50 to 70 ...

A Plant‐Based Platform for the Production of Bark Beetle Pheromones
Plant Biotechnology Journal, EarlyView.ABSTRACT Bark beetle species of the genera Ips and Dendroctonus represent a threat to forests in both North America and Europe. Under normal circumstances, these beetles recycle dying trees into nutrients, but under certain conditions, growing populations can overcome healthy tree defenses and cause severe economic loss in forestry.

PREPARATION OF TiO2/PERLITE COMPOSITES BY USING 23-1 FRACTIONAL FACTORIAL DESIGN
Journal of the Turkish Chemical Society, Section A: Chemistry, 2016 Successive impregnation and calcination process was performed in order to produce TiO2/perlite composites. 23-1 fractional factorial design was first applied to optimize the production conditions of TiO2/perlite photocatalysts.
