Marine-friendly antifouling coating based on the use of a fatty acid derivative as a pigment

et al. 2014

This study was devoted to examining the application of copper dodecanoate as a non-contaminant antifouling pigment due to its low copper content and fatty acid nature. For this purpose, antifouling paints with mono-component epoxy resin and rosin matrixes were formulated, and their antifouling efficiency was evaluated. Before its incorporation into the different formulations, the synthesized pigment was characterized. Immersion tests in a marine environment were carried out for 12 months to evaluate the antifouling efficiency of the developed paints; the results were compared with those from a commercial paint. The antifouling efficiency of the new epoxy formulation was found to be considerably higher than that of the rosin formulation and very similar to that of the commercial paint. Most importantly, the release of copper from the epoxy paint formulated with copper dodecanoate was 73.5% lower than that of the commercial paint, suggesting prolonged activity of the developed paint.

“…The period of repellency from the TTO emulsions was equivalent to or longer than that reported with most other plant extracts (reviewed by Bissinger and Roe, 2010), with concentrations of 4% and 5% TTO giving complete repellency up to 24 h, and the 5% TTO providing 77% repellency at 48 hours. In the extended protection study the 3% emulsion gave greater than 60% repellency for 6 days.…”

“…Repellent effects can be mediated by a number of mechanisms (Bissinger and Roe, 2010;Halos et al, 2012). With tick larvae a repellent could prevent attachment to a passing host, unfavourable tactile stimuli could cause larvae to subsequently disengage from the host, or a repellent or stimulation of tactile or gustatory sensors could prevent the larvae from successfully attaching and commencing blood feeding.…”

Repellent effects of Abstract:Rhipicephalus australis (formerly Boophilus microplus) is a one host tick responsible for major economic loss in tropical and subtropical cattle production enterprises.Control is largely dependent on the application of acaricides but resistance has developed to most currently registered chemical groups. Repellent compounds that prevent initial attachment of tick larvae offer a potential alternative to control with chemical toxicants. The repellent effects of Melaleuca alternifolia oil (TTO) emulsions and two β-cyclodextrin complex formulations, a slow release form (SR) and a modified faster release form (FR), were examined in a series of laboratory studies.Emulsions containing 4% and 5% TTO applied to cattle hair in laboratory studies completely repelled ascending tick larvae for 24 h whereas 2% and 3% formulations provided 80% protection. At 48 h, 5% TTO provided 78% repellency but lower concentrations repelled less than 60% of larvae. In a study conducted over 15 days, 3% TTO emulsion applied to cattle hair provided close to 100% repellency for 2 days, but then protection fell to 23% by day 15. The FR formulation gave significantly greater repellency than the emulsion and the SR formulation from day 3 until the end of the study (P<0.05), providing almost complete repellency at day 3 (99.5%), then decreasing over the period of the study to 49% repellency at day 15.Proof of concept is established for the use of appropriately designed controlledrelease formulations to extend the period of repellency provided by TTO against R. australis larvae.

“…Spatial repellents work by repelling at a distance, while contact repellents require an insect to physically contact a chemical to elicit a repellent action (Dethier 1947, Gouck et al 1967, Bissinger and Roe 2014. Repellent chemicals can potentially have both spatial or contact activity (Bissinger and Roe 2010). DEET has been shown to act as a better contact repellent at times and, at other times, it has been shown to be an effective spatial repellent (Khan andMaibach 1972, Bernier et al 2005).…”

The loss of managed honey bee colonies, resulting from their unintentional exposure to pesticides, is a topic of concern for the agricultural and apicultural industry. Current methods for reducing pesticide exposure to bees involve the application of pesticides before crop bloom or in the evening when foraging bees are less likely to be exposed to these applications. There is an urgent need for additional protection procedures to reduce the annual losses of managed bee colonies. Another method for protecting these pollinators is the use of chemical deterrents to reduce the interaction times of foraging bees with pesticide-treated crops. Historically, insect repellents (IRs) have been used to prevent the spread of deadly human diseases by arthropod vectors. However, it has been shown that bees can be repelled from pesticide-treated crops using DEET and bee pheromonal compounds. Here, I report the toxicological and deterrent effects of bee pheromonal compounds, as well as the deterrent effects of heterocyclic amines (HCAs) on bees. The results of this study indicate that the bee pheromonal compounds, at 8, 20, 60 and 100% concentrations, are toxic to bees and inhibit the feeding of bees within a confined space. Additionally, the pheromonal compounds and the HCAs are as efficacious as DEET in deterring bees from treated food sources.The HCA piperidine, was observed to effectively deter bee foragers from a sugar feeder in a hightunnel experiment as well as from melon flowers and knapweed in field experiments.Electroantennogram recordings were conducted to verify an olfactory response of the bees to the tested compounds. Pheromonal compounds were readily detected by bee antennae; whereas, the HCAs did not elicit significant responses in the bee antennae. These data suggest that bee pheromonal compounds, as well as HCAs, may serve as candidates for the further investigation as repellents to protect bees from unintentional pesticide exposures.

Current methods for reducing pesticide exposures to bees involve the application of pesticides before crop bloom or in the evening when foraging bees are less likely to be exposed to these applications. There is an urgent need for additional protection procedures to reduce the annual losses of managed bee colonies.One method for protecting these pollinators is use of chemical deterrents to reduce the interaction times of foraging bees with pesticide-treated crops. Insect repellents (IRs) primarily have been used for biting and blood-feeding arthropod pests. However, it has been shown that bees can be repelled from pesticide-treated crops using DEET and bee pheromonal compounds. Here, I report the toxicological and deterrent effects of bee pheromonal compounds as well as the deterrent effects of heterocyclic amines (HCAs)...
