Abstract

The authors record fifteen insect species which were found causing damage to ghont (Zizyphus xylopyra), an important plant species, in its natural environs in Damoh, Madhya Pradesh. The parasites of these insects, reared in the laboratory, have also been recorded. Biological notes on each insect species have also been given under each in the text. Mathur and Singh (1960) record 14 insect species on ghont.

Abstract

Suitable age of shoots, at the time of introduction of the lac insect on them, is necessary for the latter's successful colonization and the ultimate increased yield of lac. Systematic trails of the culture on ghont (Zizyphus xylopyra Willd) in Uttar Pradesh were carried out for the first time. Results indicate that (i) for raising Katki crop (June-July to October- November cycle), the trees should be pruned in May for introducing lac insects on them in June-July of the following year i.e. on 13-14 months old shoots. (ii) for raising Baisakhi crop (October-November to June-July cycle), the trees should be pruned in April for introducing lac insects on them in October-November the same year i.e. on 6-7 months old shoots.
