This is essentially a vertical shooter. Don't focus on spraying DK all the way to the top unless you have the super sprayer, just kill all the bugs and the level will end. This is especially key on the level with the missing platform in the center.
On the level where he is throwing coconuts at you, he alternates between throwing one directly at you, and throwing one at a hive to release bugs. Keep track of which one he is on, and be ready to dodge the one coming for you. You need to move quick, don't be in the middle of a level change or jumping in the air to shoot him. On these levels you do have to spray him to the top, but it is quite easy to do as he doesn't release very many bugs at once. Remember that shooting the caterpillars just stuns them and keeps them in your way, so when you are trying to spray DK to the top on this round, don't hit the caterpillars, let them crawl past your line of fire.
Don't "run and gun" the bumblebees, as they split into parts that will kill you, always be directly under them and stay there until the shrapnel is past.
The blue wasps will fix on your vertical position from the sides and then VERY quickly move in for the kill. Get under them by dropping down one level and shooting them from underneath after they fix on you but BEFORE they move in. If you see blue wasps coming out of the hives, do NOT be on the very bottom , as you won't be able to kill them after you dodge their attack until you move under them again.
