RESUMO
Aqua Reslin and Biomist 30:30 technical permethrin and piperonyl butoxide were applied via ground ultra-low volume at a rate of 237 ml/min and 0.00196 kg active ingredient/ha against wild-caught adult Anopheles quadrimaculatus. The 2 formulations did not differ significantly at 31 m from the spray path (P < or = 0.05). However, at 61 and 91 m, percent mortality for 30:30 was significantly higher than for Aqua Reslin at each time after treatment (P < or = 0.05). Between 12 and 24 h, about 8% recovery was observed in mosquitoes treated with Aqua Reslin at 31 m.

The effect of sodium heparin on the determination of the major arterial blood gas parameters was studied. The addition of heparin produced errors in all three parameters tested, i.e. PO2, PCO2 and pH. The PCO2 determination was most affected, a 12% decrease being introduced into a 1.5 ml blood sample by the volume of heparin which fills the deadspace of a syringe and needle. Small but statistically significant errors were also produced in PO2 and pH by this heparin concentration. The clinical implications of these findings are discussed and certain measures outlined to avoid such errors.
