Well I'm no authority, to say the least, on pest problems in Dubai, but as a general rule unless they are doing damage or unless there is a severe infestation then there is no need to do anything.

Most "bugs" in the garden pose no threat but unnecessary spraying of chemicals, no matter the type, does. So seeing some bug doesn't automatically mean you need to drag out the pesticide. You learned that with the leaf miners. :)

It is impossible to tell from the pics what it is. it may be a black winged aphid but it could also be 100 other types of small flies or gnats attracted to the moisture. I wouldn't worry abut it but if you want to spray something then first make sure that pesticide lists it is effective for the pest and then avoid spraying the fruit directly as much as possible.

Does the lable give any indication of holding times when used on plants for food? If it does it should be safe to use, just be sure to wash the fruits well.

Personally for those little gnats, I'd use an insecticidal soap such as the Safer brand. Failing that you can make your own by using the recipe at this link: Homemade Insecticidal Soap It is pretty darn simple, you just need to make sure you are getting SOAP and not detergent.

I've been keeping an eye on our Perigrine Falcons in Boise, ID for several years now. The Falcons have come back to the nest, but haven't laid any eggs yet.
