Abstract
Testes removed from Schistocerca gregaria, injected with 5 or 7 mu g a zadirachtin g(-1) body wt on day 0-2 of the Vth instar and killed by d ecapitation 20 days after treatment, showed significant reductions bet ween the widths, lengths and volumes of the treated groups, compared t o control insects. Under cytological examination these testes, from in sects exhibiting classical signs of azadirachtin poisoning, showed arr ested spermatogenic meiosis at Metaphase I. (C) 1997 Elsevier Science Ltd.
