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
