The formamidine acaricides and insecticides, chlordimeform and ami-traz, are lethal to all life stages of acarines, but their activity to insects is considerably more restricted (1). Using the southern cattle tick, Boophilus microplus, and the twospotted spider mite, Tetranychus urticae, the structural requirements of formamidines for lethality have been elucidated ( -5), an< t ie structure (lethal moiety) for maximum activity is shown in Figure 1. Briefly, the ring must contain two substituents, and they must be located at positions two and four maximum activity was observed when position... 

The acaricidal activity of Piquerols A and B against the common cattle ticks Boophilus microplus was also tested [59]. Both compounds induced 100% mortality at a concentration of 300 Xg/ml on larvae and gravid female ticks. TTieir activity was similar to that exhibited by commercial organophosphorus acaricides tested with the same protocol and at similar concentrations. However, piquerol A and B did not prevented ovoposition as the organophosphorus acaricides did [122]. 

Ixodidin, an antimicrobial 65-peptide from the hemocytes of the cattle tick Boophilus microplus, with inhibitory activity against serine proteases. The name is derived from the family Ixodidae. The 65-mer ixodidin contains five intrachenar disulfide bonds and an N-terminal pyroglutamic acid residue. In addition to growth inhibition of E.coli and Micrococcus luteus, it exerts inhibitory activity against elastase...

In South America the tick Boophilus annulatis microplus transmits the organism of redwater and the disease is endemic among cattle on most of the northern half of the continent. The standard arsenical sprays no longer control this tick adequately and reinfestation develops rapidly following dipping or spraying with them.

In South America, as in Africa, toxaphene is at present the material of choice for tick control on cattle. Applied as a spray at the 0.25% dosage, toxaphene controls Boophilus annulatus microplus for nearly 4 weeks. Raising the dosage to 0.75% produced no significant increased the duration of control, according to Laake. A mixture containing 0.25% benzene hexachloride and 0.50% DDT was notably less effective than 0.25% toxaphene.
