Oh Crap! Gerardo, I hate reading this, and I can empathize. I have had minor issues with thrips, but I was getting more problems from the suck bugs. Oddly, expensively, but happily, lightning struck and killed my bishofia tree in the back yard. $2200.00 later, tree gone, stump ground, and not a single engytatus modestus this year, plus lots more full sun area to plant things in. Yipee!
The local Rare Fruit Council had their annual sale this past weekend, I got a Cacao for under the mango tree, thanks for the suggestion, plus a Nam Doc Mai- (Siatung cultivar)Mango, and a pomegranate.
Your comment about hair on your chest cracked me up.
And I can understand! I know that resolve well.
I have to look up some of those poisons you mentioned, I confess I haven't heard of them. When your whole crop is threatened, it's amazing how quickly organic methods can go town the flusher. People who live with frost and cold don't really get just how many insects live in paradise.
