In September 2021 we started the big field experiment in the Piedmont region, a highly infested zone. Giovanni Bosio from the plant health service of the Piedmont region found meadows which were not treated yet and with willing owners to let us do ex...

#IPMPopillia
In collaboration with colleagues from CREA (Florence), we have treated popillias with three experimental control protocols that appear as promising candidates in their hands. Treated popillias have been snap frozen for molecular analysis. In the next...

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.
