Instead of spraying a field with chemicals a plane disperses tens of thousands of tiny wasps over the growing plants What is the most likely reason for such an action?

A very good idea! This is using nature to get rid of pests, rather than fighting nature by using chemicals.
The farmer obviously has a problem with insect pests in the crop. The wasps will kill and eat these pests. They will eventually die out so will not become a pest themselves.

Why do female Syrian hamsters smell?
could be a number of things. maybe you should buy some spray on shampoo like i had for my hammy. the company is Hagen. it comes out like a foam and you don't have to rinse it out. it smells a little funny but it also helps with lice or fleas (or prevents if your hammy doesn't already have them). and it's really easy to use. you can use it without any water. just spray on (i would recommend spraying on a cloth first instead and then wiping them with the stuff instead of spraying directly on them because it scares them pretty bad sometimes mostly the noise but also the feeling) and leave it.
What household chemicals can kill cats?
Household chemicals that are hazardous to humans are also hazardous to cats. Keep them out of the laundry room! Also, antifreeze is especially deadly to indoor/outdoor cats. Cats don't normally ingest antifreeze directly, but instead lick it off their paws when they accidently walk through it. This can typically happen when cars are leaking antifreeze.
Will a female cat who is pregnant spray?
She's probably in heat. I'd get her spayed either way. There are too many homeless cats in the world to be bringing more into it. Make sure you clean all the areas she's sprayed with an enzyme cleaner you can find at a pet store, or even after you get her spayed she'll keep doing it.

This is a very vague question, but there will always be bugs outside. The best thing to do is to set traps instead of spraying. Setting traps will attract the bugs to them, but will not hurt the plants.
What do goldfish smell?
A goldfish does have a nose but its nares (like nostrils) are not connected to its mouth. Instead it is connected to a chamber lined with sensory pads. A goldfish can smell various chemicals in the water when that water is passed over its sensory pads. There are chemicals that are a signal for food, chemicals that signal a predator, chemicals that signal when it's breeding time or even chemicals that are given off by wounded or alarmed fish.
