Summary
[edit]DescriptionMango leaf webber (Caterpillar) (25185341293).jpg |
Orthaga exvinacea, Family: Pyralidae Orthaga exvinacea is a species of snout moth in the genus Orthaga. Orthaga exvinacea is considered a major pest of mango and cashew in India. The larvae web the leaves and terminal shoots into clusters. A webbed cluster of leaves may harbour several larvae in the initial stage. The larvae are initially gregarious and feed by scraping the leaf surface. Late-instar larvae feed individually on the whole leaf lamina leaving only the midrib. As a consequence of severe feeding, clusters of webbed leaves become dry and brown in colour. With severe infestation, the shoots become dry and photosynthesis is severely hampered. Trees which bear clusters of affected leaves present a sickly appearance and can be seen from a distance due to the brown, dried, clustered leaves. Although variation exists in the degree of infestation by Orthaga spp. in different commercial varieties of mango, none are resistant. |
