Eucalyptus Clones and Species Against Gall Insect on Morphology Basis 12+

📕 This book includes information about evaluation of Eucalyptus clones and species against gall insect Leptocybe invasa Fisher and La Salle (Hymenoptera: Eulophidae) on morphological basis. Eucalyptus is extensively cultivated in Gujarat by wood based industries,State Forest Development Corporation and tree farmers in social forestry or farm forestry. In Gujarat it has been reported to be damaged by gall wasp or blue gum chalcid on seedlings and young trees. In mature trees, the galls occur only on leaf midribs. Eucalyptus trees up to two years of age have been found more prone to the pest.The evaluations were carried out on 15 Eucalyptus clones at NAU; Navsari viz., P-72, P-1, P-105, P-316, P-407, P-498, P-2070, P-3020, P-2045, BCM-271, P-2069, BCM-2253, BCM-413, BCM-272, BCM-288 and two Eucalyptus species viz; Eucalyptus camaldulensis and E. citriodora in south gujarat condition. The investigations evaluated Eucalyptus clones and species against Eucalyptus gall insect Leptocybe invasa under field condition and also to studied role of morphological characters on incidence of the pest species.
