From plant to fabric: Environmental opportunities associated with annatto dye for sustainable development in the textile industry

open access: yesColoration Technology, EarlyView.
Abstract Natural dyes are compounds that occur naturally in several organisms and are classified based on chemical structure and application method. The literature cites several natural dyes used in industrial transformation processes. Annatto dye is used in the food industry, and its biological pigment is extracted from the annatto seed. However, this

Potential repellency of cedarwood oil from a novel extraction method to stored product insects [PDF]

open access: yes, 2018
Producers lose 10-30% of crops during storage, processing, and marketing after harvest each year to stored product insects (1,2). Globally, there has been a rise in insecticide resistance to phosphine, the most common fumigant for these pests (3).

Beauveria Bassiana Triggers Soybean Systemic Resistance and Causes Sublethal Effects in Spodoptera frugiperda

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
The interaction of soybean plant and the endophytic microorganism Beauveria bassiana was evaluated by inoculating a single trifoliate leaf. The effects of this inoculation on the herbivory, larval development, and life traits of Spodoptera frugiperda were measured.

Repellent, irritant and toxic effects of plant EO compounds on the malaria vector Anopheles gambiae ss Giles [PDF]

open access: yes, 2013
yrethroids resistance has become widespread among malaria vector Anopheles gambiae populations in Africa. Alternative insecticides must be considered to prevent diseases transmission by An. gambiae bites. The long lasted treated bed nets are particularly

A New Experimental Setup to Study the Olfactory Behaviour of Trichogramma Egg Parasitoids

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
We developed an experimental setup to assess odor‐induced egg‐laying behavior in tiny egg‐parasitoid wasps. This Y‐shaped olfactometer, coupled with an AI‐based image‐recognition model, automatically quantifies egg parasitism by Trichogramma wasps. Olfactory‐driven egg‐laying preferences were analyzed using Bayesian inference.

Two Metschnikowia nectar yeast species have similar volatile profiles but elicit differential foraging in bee pollinators

open access: yesEcological Entomology, EarlyView.
Yeasts that specialize in flower nectar play an important role in pollination ecology. Metschnikowia reukaufii and Metschnikowia koreensis were the most prevalent nectar yeasts found in our field sites. Bee pollinators exhibited different behavioural responses to nectar yeasts in field experiments. Bees visited more flowers with M.

When Similar Individuals Don't Attract: Absence of Assortative Mating by Coloration in a Damselfly With Honest Signaling

open access: yesEthology, EarlyView.
In Acanthagrion lancea damselflies, both sexes display blue ornamentation, but do they choose mates based on it? We tested whether mutual mate choice and time constraints influence ornament evolution. Blue coloration correlated with individual quality, but individuals did not choose mates based on color, and this was unaffected by time constraints over

Expanding the substrate scope of a bacterial monoterpene synthase for the production of sesquiterpenoid and diterpenoid products

open access: yesThe FEBS Journal, EarlyView.
We have converted the only known true bacterial monoterpene synthase, cineole synthase from Streptomyces clavuligerus (bCinS, C10 substrate), to a highly competent sesquiterpene synthase (C15) with a minimum number of rational mutations. By comparison with diterpene synthases (C20), we were then able to bestow diterpene synthase activity on bCinS. This
