did the trap worked against Aedes, when tested at peak hours of Aedes activities?

Good Question! and I think you know the answer....NO! Have not found a trap that will work in the daytime when applied outdoors. If it works indoors, it is normally due to the mosquitoes having nowhere to go and eventually gets trapped, but not by deliberate design.

Even though aedes have been described as a daytime feeder by entomologists, I have not found papers that says they are "exclusive" and will not feed also at night. What I can confirm is that the MMA is "attractive" for the Aedes mosquitoes day or night.

Clearly, a true human host is far more complete and attractive for mosquitoes, aedes or otherwsie.

This "completeness" is the threshold that researchers are attempting to match or exceed, the ultimate solution.

We are not there yet, as the true human host includes size, heat, movement, scent [all sorts] and blood.

However, even though the current MMA semiochemical and trap do not work in the daytime, it is effective at night. The ability to trap the mosquitoes at night leaves only the incoming daytime mosquitoes to deal with, which is the final part of the ongoing investigation.

The current research and trials suggests that daytime trapping requires "additional" stimulants and improvement to the MMA, but I am not at liberty to discuss this, except to say that early morning trapping has been partially successful due to such work. Trapped mosquitoes dehydrate and die within a certain time, and it became possible to the estimate trapping time period when live mosquitoes are found in the traps in the late afternoon/evening.

Such advancements, even though modest, enforces the conviction that semiochemicals, [pheromones, allomones, kairomones, attractants and repellents], holds great promise as new tools for vector control.

This post is to inform those who are interested and to encourage those who are already working in/ studying  this particular branch of biotech science.

There should be plenty of scientific papers describing Aedes as biters during dawn and dusks...something to do with the light spectrum at that time..

Aedes does not bite at night. IF the MMA is effective at night and not proven to work at daytime, i hope those responsible for marketing this product DO NOT RIDE ON THE DENGUE ISSUE just to promote and sell their gadgets...

the last thing we want is for the public to take more important issues such as cleaning house area, clogged drains and breeding sites lightly, just because they think a mosquite trapper is able to save them...

i am not against the product or any product but knowing the attitude of MAlaysians, its important that facts are provided correctly...

interesting findings, especially on the Aedes biting activities.

the published study in Carribean you mentioned is exactly what i meant...dusk and dawn...that's when Aedes is most active...not at night...

You mentioned about a study concluded that Aedes becomes active at night and its due to the fact that there's no longer a total darkness in urban environment.
Can i have a reference as of how this study is conducted? is it using the leg biting trial? I've been personally involved in leg biting trial many years ago as a graduate student. Even in areas heavily infested with Aedes, whenever we conduct leg biting trial from 7-10pm, its always the Culex that bites. We hardly caught any Aedes.

This recent study you mentioned should be ground breaking and interesting. will love to have the actual reference and statistics. Surely this kind of study deserves to be published and not patented. IF the MMA traps and other traps all caught Aedes at night, perhaps publication is not priority as compared to patenting. That i can understand.

But if its a simple but reliable leg biting trial, it should be interesting. In addition, its not just about fooling mosquitos just because there are presence of light at night to induce them to bite. Aedes mosquitoes biting behaviour is also strongly related to the classic endophagous/exophagous (activity), endophilic/exophilic (resting) cycle. Meaning, if they bite at night, then they will need to change their resting behaviour as well. it has been years since i was involved in vector control research. It will be a huge impact and important finding, to know that Aedes aegyptii or albopictus actually bite at night as well. That is frightening....and worrying...
