| Sujet: Urgent: Antherina suraka larvae with strange symptoms Mer 1 Fév à 19:43 | |
| I'm rearing several suraka larvae since L1 successfully on Nerium oleander. But today some of the L5 started to have suddenly strange symptoms of suffering: they start to vomiting or have diarrhea and twist, then they fall on the bottom of container and continue to twist and loose green liquid from the mouth. I don't think it is a disease but some plant with some insecticide (altough I wash plants in water for 30 minutes before offering to larvae) . Or maybe it can be some little Acarus who remain on washed leaves? I saw a similar sympthoms with several others Saturniidae in the past and also with plants which probably are not treated by insecticide (es. Rubus fruticosus).

| My "poisoned" larvae recovered a little yesterday after being kept the day before "drowning" in tiepid water for 15 minutes and then let dry on a paper-towel. Maybe it was a stupid trick but I had wanted to try anyway! Today they are feeding!  The other larvae seemed to be not affected by the insecticide in leaves. Yesterday I provided Nerium oleander branches from another source and washed leaves keeping them in a solution of water + bi-carbonate and then with a solution 0,5% of bleach! Then I rinsed well the branches and gave to the larvae, which since yesterday are feeding without warning symptoms. _________________ Mario http://www.ecosicilia.net/saturniaweb |
