[LEPS-L:7859] RE: aerial spraying is "DEVASTATING to non-target species

[Jean-Michel MAES]

WOW... I remember I have read some articles telling that Bacillus
thuringiensis israelensis is attacking only mosquitoes and do not kill
Odonata. Is this wrong ? Could it be possible that Bacillus is spread with
another product together ? Detergent perhaps ? I would be interested in that
information because I have been very critical against Health Ministry here
in Nicaragua because they use Methyl Paration in diesel to fumigate against
adult mosquitoes in stead of killing larvae with Bacillus. I hope I am not
so wrong ?
