Effects Of Addition Of A Bird Repellent To Fish Diets On Their Growth And Bioaccumulation, Sheenan Harpaz, Larry Clark Jan 2006

Effects Of Addition Of A Bird Repellent To Fish Diets On Their Growth And Bioaccumulation, Sheenan Harpaz, Larry Clark

USDA Wildlife Services: Staff Publications

The effects of adding the nonlethal bird repellent methyl anthranilate (MA), at levels of 100 and 1000 mg/kg, to fish feed on the bioaccumulation and growth of juvenile (10 g) hybrid striped bass (Morone chrysops x M. saxatilis) and juvenile (1g) African cichlid fish Aulonocara jacobfreibergi were investigated under laboratory conditions. The bird repellent did not have any effect on the fish growth or survival over a period of 6 weeks. MA residues at low levels of 11.2 ± 2.6 mg/g were found in lipophili tissues (liver) of MA-fed fish. Control fish, which had no MA added to their diet, …


Evaluation Of Chemical Repellents For Reducing Crop Damage By Dickcissels In Venezuela, M. L. Avery, E. A. Tillman, C.C. Lauker Oct 2001

Evaluation Of Chemical Repellents For Reducing Crop Damage By Dickcissels In Venezuela, M. L. Avery, E. A. Tillman, C.C. Lauker

USDA Wildlife Services: Staff Publications

In Venezuela, lethal control of wintering Dickcissels (Spiza americana) is considered a threat to the species survival. To help farmers protect their rice and sorghum crops from depredations by Dickcissels and to minimize the killing of large numbers of these birds, alternative non-lethal crop protection measures are needed. To that end, the responses of captive Dickcissels to three bird-repellent chemicals applied to rice seed were evaluated. In one-cup feeding trials, treatments of methiocarb (0.05% g g-1, applied as Mesurol® 75% wettable powder) and anthraquinone (0.5%, applied as Flight Control® ) reduced consumption of rice by 70% …


Rejex-It® Bird Repellents - Mode Of Action, Peter F. Vogt Sep 2000

Rejex-It® Bird Repellents - Mode Of Action, Peter F. Vogt

Wildlife Damage Management Conference Proceedings

Rejex-it® bird repellents are used to repel birds and reduce bird predation. Rejex-it® represents a long-needed, logical alternative to inhumane bird control methods such as poisoning and shooting. Its effectiveness as a nuisance bird repellant is based on a common, naturally-occurring, com lly recognized as safe" food and ponent of food that has been designated by the FDA as a "generafragrance additive. Methyl Anthranilate (MA), the active ingredient in Rejex-it® Bird Repellents, acts as a sensory repellent by irri tating the bird's taste buds, skin, and trigeminal chemoreceptors in the beaks, gizzards, eyes, and mucous membranes. Irritation occurs as a …


Recent Developments In The Use Of Flight Control To Repel Birds From Airports, Kenneth E. Ballinger Jr., Michael K. Gilmore, Rebecca W. Price May 1999

Recent Developments In The Use Of Flight Control To Repel Birds From Airports, Kenneth E. Ballinger Jr., Michael K. Gilmore, Rebecca W. Price

1999 Bird Strike Committee-USA/Canada, First Joint Annual Meeting, Vancouver, BC

Birds found at or near airport flight operations pose a threat to aircraft. There were 2843 reported bird strikes in the United States in 1997 and 837 reported bird strikes in Canada for the year 1998. Potential for loss of life and economic losses due to aircraft damage have driven the need for research into effective techniques in lowering the risk of bird strike in the immediate area of flight operations. Flight ControlÔ is a documented bird repellent. Flight ControlÔ was released commercially in January 1999 in the United States for use on turf, ornamental trees and bushes, building surfaces …


Complete Control Of Nuisance Birds In Airport Hangars, Peter F. Vogt May 1999

Complete Control Of Nuisance Birds In Airport Hangars, Peter F. Vogt

1999 Bird Strike Committee-USA/Canada, First Joint Annual Meeting, Vancouver, BC

Fogging of ReJeX-iT7 TP-40 offers a very efficient method for the control and dispersal of nuisance birds from many diverse areas. The amount of the repellent is greatly reduced over any other control method. The method is direct and is independent of the activity of the birds. The applications with any fogger, thermal or mechanical, that can deliver droplets of less than 20 microns, can be manually or fully automated and pose only minimal risks to operators or animals. All birds that became a nuisance and safety problem in the hangars of TWA and AA at LaGuardia, and TWA warehouse …


Development Of Seed Treatments To Control Blackbirds, Michael L. Avery, David Decker, John S. Humphrey Jan 1998

Development Of Seed Treatments To Control Blackbirds, Michael L. Avery, David Decker, John S. Humphrey

Proceedings of the Eighteenth Vertebrate Pest Conference (1998)

Bird repellents to protect seeds are a potentially important aspect of integrated vertebrate pest management strategies. Yet, there currently are no repellents registered for seed treatment uses. This is due not to lack of effective candidate compounds, but to monetary and regulatory constraints that inhibit commercialization of promising compounds. Two examples of this dilemma are methiocarb and anthraquinone, each of which has considerable potential for bird repellent uses and each of which faces considerable registration hurdles as prospective seed treatment compounds. A concerted, coordinated effort among private industry, producer groups, and state and federal agencies may be the best strategy …


Effectiveness Of Dimethyl Anthranilate And Eyespots For Reducing Feed Consumption By Starlings, Michael L. Avery, Raymond E. Matteson Oct 1993

Effectiveness Of Dimethyl Anthranilate And Eyespots For Reducing Feed Consumption By Starlings, Michael L. Avery, Raymond E. Matteson

Sixth Eastern Wildlife Damage Control Conference (1993)

The bird repellent properties of methyl anthranilate (MA) and dimethyl anthranilate (DMA) are well-established. Nevertheless, development of means to reduce the amount of chemical needed to effect satisfactory repellency would reduce costs and make their use even more attractive. Thus, we evaluated the usefulness of a visual stimulus for increasing DMA repellency. We offered groups of captive European starlings (Sturnus vulgaris) untreated food and DMA-treated food, and to some groups we also presented a putatively repellent eyespot pattern. As expected, a DMA concentration of 1.4% (gig) reduced (P = 0.001) consumption of treated food compared to untreated; 0.3% DMA was …
