Thank you for the comments everyone. In Japan, we can buy DDVP for domestic use, but, we have to make signature at shop when we buy them, sometimes ID needed to. I used to use DDVP for trap. But, as stupid beetles and moths destroy my craneflies before they die, I started to use Ethanor or propylene glycol. |

Jorge, amd maybe other people, here in Greece I have found that the plastic of the connecting ring deteriorates in the sun, and then the bottle falls out and you can lose some catch, also it is tricky to make a new one, although I have done it. What is better is to wrap a few cycles of electric tape around the connector, this helps protect it from the sun and prolongs its life. The sun is a powerful force here in the south. Gordon |

Here is a picture that is self explanatory, the bottles are 250 ml. It is one week's worth of Malaise samples, but note that the Sultanitsa trap, while not the best is doing pretty well thank you.

The important thing about the Sultanitsa trap is that it wasn't a malaise trap. See picture. I do not of course know what a true malaise trap would have caught in the same place, but a lot of stuff could have escaped at ground level, it was very uneven and treacherous.
