Abstract Yeasts play an important role in the life cycle and biology of insect pest Drosophila suzukii (Matsumura), commonly known as spotted wing drosophila (SWD). Adult larvae this species are to feed benefit from yeast their diet. In addition, yeasts were found be attractive SWD repeatedly associated with SWD. Among those, Hanseniaspora uvarum is most mentioned. The present study explores chemical composition effects three H. strains five ( Saccharomyces cerevisiae, Candida sp., Issatchenkia terricola, Metschnikowia pulcherrima Saccharomycopsis vini ) diet adults. different used influenced mortality, fecundity ingestion by females.

Re‐evaluation of erythritol (E 968) as a food additive

EFSA Journal, Год журнала: 2023, Номер 21(12)

Abstract This opinion addresses the re-evaluation of erythritol (E 968) as food additive and an application for its exemption from laxative warning label requirement established under Regulation (EU) No 1169/2011. Erythritol is a polyol obtained by fermentation with Moniliella pollinis BC or megachiliensis KW3-6, followed purifications drying. readily dose-dependently absorbed in humans can be metabolised to erythronate small extent. then excreted unchanged urine. It does not raise concerns regarding genotoxicity. The dataset evaluated consisted human interventional studies.

A series of methods incorporating deep learning and computer vision techniques in the study of fruit fly (Diptera: Tephritidae) regurgitation

Frontiers in Plant Science, Год журнала: 2024, Номер 14

Опубликована: Янв. 15, 2024

In this study, we explored the potential of fruit fly regurgitation as a window to understand complex behaviors, such predation and defense mechanisms, with implications for species-specific control measures that can enhance quality yield. We leverage deep learning computer vision technologies propose three distinct methodologies advance recognition, extraction, trajectory tracking regurgitation. These methods show promise broader applications in insect behavioral studies. Our evaluations indicate I3D model achieved Top-1 Accuracy 96.3% which is notable improvement over C3D X3D models. The segmentation regurgitated substance via combined U-Net CBAM framework attains an MIOU 90.96%, outperforming standard network Furthermore, utilized threshold OpenCV precise quantification liquid, while integration Yolov5 DeepSort algorithms provided 99.8% accuracy detection tracking. success these suggests their efficacy research comprehensive tool interdisciplinary behavior analysis, leading more efficient non-destructive strategies agricultural settings.

Diuresis and α-glucosidase inhibition by erythritol in Aedes aegypti (Diptera: Culicidae) and viability for efficacy against mosquitoes

Sugar alcohols, such as erythritol, are low-impact candidates for attractive toxic sugar baits (ATSB) to kill mosquitoes. To determine whether erythritol has a viable future in ATSB formulations, suite of assays was conducted diagnose toxicity mechanisms and starvation effects on mortality Aedes aegypti (L.) model system. We measured general carbohydrate load, glucosidase levels, free glucose intoxicated adult mosquitoes observe digestion impaired. assayed the combinations with larvae adults. measure when were not resource-deprived, additional manipulated prior status. Up 50,000 ppm water had no effect within 72 h, but an ammonia spike indicated diuresis early 4 h (F8,44 = 22.50, P < 0.0001) after sucrose/erythritol added.

The Impact of Artificial Sweeteners on Insects

Journal of Economic Entomology, Год журнала: 2020, Номер 114(1), С. 1 - 13

Опубликована: Сен. 25, 2020

Artificial sweeteners are sweet-tasting additives found in consumable products as substitutes for naturally occurring sugars. They derived from plant extracts or manufactured by chemical synthesis. Ingestion of insects can lead to significant physiological effects, such mortality, decreased fecundity, and behavioral change. Due their low toxicity toward humans the issues associated with conventional insecticide usage, artificial have recently gained attention potential use biorational insecticides. Here, we review impact on novel

Erythritol Ingestion Causes Concentration-Dependent Mortality in Eastern Subterranean Termites (Blattodea: Rhinotermitidae)

Journal of Economic Entomology, Год журнала: 2019, Номер unknown

Опубликована: Авг. 31, 2019

Damage from termite infestations is economically significant and control can be costly when requiring the widespread use of conventional insecticides. Erythritol, a polyalcohol sweetener that safe for human consumption, causes increased mortality ingested by some insects, indicating potential as alternative insecticide. Here, we investigated applicability erythritol novel toxicant method control. Eastern subterranean termites, Reticulitermes flavipes Kollar (Blattodea: Rhinotermitidae), were fed paper foods treated with increasing concentrations assessed bait consumption. Termite survival to 8 d (the duration experiment) significantly decreased treatment concentration increased, lethal effects concentration-dependent. Termites consumed erythritol-treated at all did not display avoidance in choice assays, suggesting may practical an ingestible bait. These results provide basis further development

Potential for Use of Erythritol as a Socially Transferrable Ingested Insecticide for Ants (Hymenoptera: Formicidae)

Journal of Economic Entomology, Год журнала: 2020, Номер 113(3), С. 1382 - 1388

Опубликована: Янв. 20, 2020

Ants are significant structural and agricultural pests, generating a need for human-safe effective insecticides ant control. Erythritol, sugar alcohol used in many commercial food products, reduces survival diverse insect taxa including fruit flies, termites, mosquitos. Erythritol also decreases longevity red imported fire ants; however, its effects on other species ability to be transferred naïve colony members at toxic doses have not been explored. Here, we show that erythritol Tetramorium immigrans Santschi (Hymenoptera: Formicidae) concentration-dependent manner. Access ad-libitum water reduced the of erythritol, but worker mortality was still increased over controls with ad-lib water. Foraging T. workers lethal levels nest mates had directly ingested erythritol. Similar patterns following ingestion were observed Formica glacialis Wheeler Formicidae), Camponotus subarbatus Emery chromaiodes Bolton Formicidae). These findings suggest may highly insecticide several genera ants. Erythritol's potential effectiveness social control is augmented by spread through colonies via transfer (trophallaxis) between workers.
