I have some Neobicide that I use as my main dewormer, in addition to feeding a small amount of diatomaceous earth in food. Is neobicide actually ivermectin...? And if so, would it work to treat a gapeworm infection?
Thanks for any help!

Ivermectin will only work it it is applied directly to the worm .Gape worms have the ability to sense certain chemicals and will stop feeding until they have passed from the birds system .I would look for a specific treatment available in your country .Not sure what Neobicide is so cannot help there . De is generally added at a rate of 2% per kg /pound etc and works by slicing microscopic cuts into worms there by killing them as Gap worms are in the respiratory area it would have no effect on these but should have an effect on any in the gut areas,I would still suggest proper medication for infestations

Gape Worm
By Jon Baldwin on Monday, May 27, 2013 at 10:24pm

Syngamus trachea

Syngamus trachea is a parasite of the upper respiratory tract of non-aquatic birds. It is commonly known as the "gapeworm" and may be responsible for respiratory distress and death in domestic fowl and game birds such as pheasants and partridges.

Life Cycle

Eggs are passed in the feces of infected birds. Unlike other strongyloids, S. trachea larva develops within the egg until it reaches the L3 stage.



Infection may occur in one of three ways.

1. By ingestion of an egg containing an L3 (A).

2. By ingestion of the hatched L3 (B).

3. By ingestion of a transport host containing encapsulated L3s (C).

() Following ingestion, the L3s exsheath in the duodenum (D) of the final host, moult, and pair off. They penetrate the intestine and travel first to the liver and then to the lungs (E) via the bloodstreamd. Two parasitic moults take place in the lungs within 4-7 days after infection. Adult males and females pair off move up to the trachea and begin copulation in the bronchi and trachea (F).

() Eggs escape from the vulva under the bursa of the permanently attached male and are carried up the trachea in the excess mucus produced in response to infection. They are then swallowed and passed in the feces, completing the cycle.

The prepatent period is approximately two weeks with a range of 12-17 days.

Various reports have shown that adults may survive for 23-147 days in chickens, 48-224 days in turkeys and approximately 98 days in guinea fowl.

Jon Baldwin .There is a guy doing a study on them at the moment and is wanting people to contact him .......Grant Richards at Medichick pty ltd 0357664374 he also states that lungworm meds will kill Gape Worms ,he has a good write up on them in the latest volume of Australasian Poultry (volume 24 )
