| dc.description | The plants extract may be compatible with other management tactics, especially with biologicalcontrol. so the aim of this work was to evaluate the residual effect of several extracts from cedartree (C) and mahogany tree (M) (bark (C), wood (M) and leaf (F); cecropia tree (I) (bark - C andwood - M) and of the pereiro (P) (bark -C), and its possible effects on the adults of the parasitoidTrichogramma galloi(Zucchi, 1988) (Hymenoptera: Trichogrammatidae). Cards containingparasitised eggs of Diatraea saccharalis(Fabricius, 1794) (Lepidoptera: Crambidae), or containigeggs that would be submitted to the parasitoid were immersed for 30 seconds in the extracts at 5000μg.mL-1. The number of parasitised eggs and adult emergence of the parasitoid were evaluated.The highest rates of parasitism, up to 60.0%, was obtained by the control treatment, MC, MM, CCand MF, and the treatments that caused a lower percentage of parasitism, IC, IM, PC, CM andCF, respectively. The extracts of different parts of mahogany, which showed a good percentageof parasitism, affected the development of the parasitoid with a low adult emergence. The PCshowed a lower parasitism and emergence. In relation to eggs treated four days after parasitism,it was found that the control treatment had a good average in emergency (98.85%), in the samecategory of treatments IM, CF and CC, respectively. The CC extract was more selective and the PCwas the least selective for T. galloi. | en-US |
| dc.description | Os extratos vegetais podem ser compatíveis com outras táticas de manejo, principalmente com o controle biológico. Desta forma, objetivou-se neste trabalho avaliar o efeito residual dos extratos de Cedrela fissilis Vell. (Meliaceae) cedro (C) e Swietnia macrophylla King Vell. (Meliaceae) mogno (M) (casca- C), madeira (M) e folha (F); Cecropia pachystachya (Cecropiaceae) imbaúba (I) (casca - C e madeira - M) e Aspidosperma pyrifolium Mart. (Apocynaceae) pereiro (P) (casca - C), sobre adultos do parasitoide Trichogramma galloi (Zucchi, 1988) (Hymenoptera: Trichogrammatidae). Cartelas contendo ovos de Diatraea saccharalis (Fabricius, 1794) (Lepidoptera: Crambidae) parasitados, ou que seriam submetidos aos parasitoides, foram imersas por 30 segundos nos extratos a 5000 mg.mL-1. Avaliaram-se o número de ovos parasitados e a emergência dos adultos do parasitoide. As maiores taxas de parasitismo, acima de 60,0 %, foram obtidas pela testemunha, MC e MM, CC e MF; e os tratamentos que causaram menor percentagem de parasitismo foram IC, IM, PC, CM e CF, respectivamente. Os extratos das diferentes partes do mogno, que apresentaram uma boa percentagem de parasitismo, afetaram o desenvolvimento do parasitoide, com uma baixa emergência de adultos. O PC apresentou um valor baixo de parasitismo e de emergência. Em relação aos ovos tratados quatro dias após o parasitismo, verificou-se que a testemunha apresentou uma boa emergência (98,85%), semelhantes a IM, CF e CC, , respectivamente. O CC foi o extrato mais seletivo e o PC foi o menos seletivo para T. galloi.
