    Putative Dopamine Receptors.
    Three of the newly generated sequences were phylogenetically most similar to invertebrate dopamine receptors. These receptors are preferentially activated by dopamine. Dopamine has also been shown to reduce the response to conditioned stimuli as well as inhibiting retrieval of learned information in Apis mellifera [19].
    Putative 5-HT[SUB]7[/SUB] Receptor. It has also been shown to reduce conditioned olfactory responses in the honeybee Apis mellifera [19], [21].

    The mode-of-action of amitraz, a chemistry registered for tick and insect control, is presumed to have partial agonistic activity at an octopamine sensitive GPCR [8].
    Alignment of transmembrane domains of Aedes aegypti AaDOP1 and AaDOP2 and other D[SUB]1[/SUB]-like receptors. Aligned receptor amino acid sequences include each of the two D[SUB]1[/SUB]-like receptors reported in Drosophila melanogaster (D-Dop1; DopR99B/DAMB) [30], [31], [40], [44], Apis mellifera (AmDOP1; AmDOP2) [41], Ixodes scapularis (Isdop1; Isdop2) [36], [42], and Homo sapiens (HsD1, HsD5) [39], [76].

    So we will just turn our bees into junkies that can't remember what they are supposed to do?

    I can see it now. bees is pulled over for weaving during flight. Bee Police, "So whats your name buddy" Bee " err uh, Wow Man, where am I?, Look at all the pretty lights". Bee Police, :Where are you coming from and what have you been smoking"? Bee, Hey man I just came from Daves house". Bee Police, : DAVES HOUSE!!! Daves not here".

    Sorry couldn't resist.
