A preliminary study on dangerous pest of Moringa- Noorda blitealis Walk
摘要
Abstract
Background] Noorda blitealis Walk is a small moth pest newly discovered on Moringa trees. Its larvae mainly feed on leaves, and whole branches of Moringa tree become defoliated during severe damage periods. It was recently found in Yunnan Prov-ince in China, and now greatly threatens the Moringa industry. [Method] Data about N. blitealis, its host plants, geographical dis-tribution, morphology, some biological characteristics, damage, and occurrence were collected through laboratory experiments, field investigation, and literature review.[Result] Preliminary observations of artificial rearing of the larvae of N. blitealis showed that the insect took about 26.42 days from egg hatching to adult emergence, with a total larval duration of 16.17 days and a pupal period of 10.25 days. The results of field investigation indicated that the number of larvae was high and the damage was very serious. In Yuan-jiang county of Yunnan Province, the percentage of damaged trees were over 94%, and the maximum number of pests in one tree reached at 302. Statistics revealed that 80. 80% of branches were infested, and damage index was 0. 54 in the plots that were fre-quently harvested. The extent of the damage was significantly higher in the plots than the non-harvested plots. [Conclusion] Further studies on its life cycle, generation span, damage losses, control methods need to be carried out. With the increasing commercited planting scale of the Moringa, this pest may spread to other similar locations. Systemic investigation and field surveys and monitoring are needed to prevent the spread of this pest .关键词
