文摘
When contacted neem oil T. pretiosum showed a reduction in parasitism of 67%. For nanoencapsulated neem the reduction in T. prestiosum parasitism was only 26%. The use of T. pretiosum, Toona ciliata extract, nanoencapsulated neem are promising. The contact between adult T. pretiosum and neem oil should be avoided.
