Testing long-lasting insecticide-treated nets

Some years ago, when I was in Kenya to carry out a part of my PhD program on the adaptations to terrestrial life in fiddler crabs, I slept in a bed protected by an insecticide net that prevented from mosquitos' bites and related diseases. At that time I would have never thought that one day I would have used them in my research!  

 Nets as a low impact method

Indeed, one of the task of the IPM POPILLIA project in charge to CREA is to test the effectiveness of long-lasting insecticide-treated nets as a low-impact method to control P. japonica adult. This method limits the spread of chemicals over crops and requires a minimal management.

In our laboratory tests we observed that insecticide nets were very effective in killing beetles: a tarsal contact of 5 seconds between insects and net guaranteed an insect mortality ranging between 90 to 100% in base of the net used.

Attract-and-Kill devices (A&K)

To verify in the field the efficacy of the laboratory outcomes, we built attract-and-kill devices (A&K) made of the insecticide net mounted on a frame and baited with the double lure semiochemical. We tested several forms of A&Ks and measured how long the device could be considered effective over the insect's flight season. In the end we evaluated the use of A&K under certain conditions as an important tool to slow down the spread of P. japonica in infested territories.
