Evidence for horizontal (environmental) transmission of eGFP-expressing or RNaseIII mutant R. rhodnii in R. prolixus.

% of recipient insects in which horizontal transmission of modified R. rhodnii was detected
combinations of recipient insects older than first-instar + donor insects older than first-instar carrying eGFP-tagged R. rhodnii (n = 29)	79.3%
combinations of recipient insects older than first-instar + donor insects older than first-instar carrying RNaseIII mutant R. rhodnii (n = 56)	83.9%
recipient first-instar nymphs + donor insects older than first-instar carrying RNaseIII mutant R. rhodnii (n = 16)	25% (p < 0.001)
recipient first-instar nymphs + donor insects older than first-instar carrying eGFP-tagged R. rhodnii (n = 33)	0% (p < 0.001)
recipient first-instars hatched in the presence of adults carrying eGFP-tagged R. rhodnii but fed in isolation (n = 36)	0% (p < 0.001)
