Plain-English summary
Nine healthy beagle dogs were tested to see if a topical insecticide could prevent mosquito bites and the heartworm infection caused by Dirofilaria immitis. The dogs that received the insecticide had significantly fewer mosquito bites compared to those that did not receive any treatment. Additionally, the treated dogs had a much lower rate of heartworm infection, with only one-third of them becoming infected, while all untreated dogs were infected. This suggests that using this topical insecticide can effectively reduce both mosquito bites and the risk of heartworm disease in dogs.

Abstract
Inhibition and prevention of mosquito bloodsucking by a topical insecticide, and the consequent infection of Dirofilaria immitis were evaluated using a product containing 10% w/w imidacloprid plus 50% w/w permethrin (I-P solution). Nine healthy beagle dogs divided in three groups of 3 dogs each were administered I-P solution on day 3 (group 1), day 36 (group 2) and not administered (group 3 as a control) before starting the experimental infection. The results showed that the mosquito bloodsucking rate was significantly lower, 12.1% in group 1 (p<0.05) and 11.1% in group 2 (p<0.05), than the 40.6% in group 3, meaning that the inhibition rates in groups 1 and 2 against group 3 were 70.2% and 72.7%. The infection rate of experimental D. immitis infection was 33% in group 1, 33% in group 2 and 100% in group 3, meaning that the prevention rates in groups 1 and 2 against group 3 were 67% and 67%.
