INSECT PESTS OF ORANGES IN THE NORTHERN CIRCARS

Abstract

In the N. Circars orange cultivation is carried on, on a fairly extensive scale. The citrus gardens round about Ellore, in and around Palacole and in the vicinity of Rajahmundry in the Godaveri District, and those in the districts of Guntur and Kistna furnish a very imposing sight. The chief varieties grown are the Batavian oranges (Citrus sinensis), the Pomelos (Citrus decumana), the Sour lime (Citrus medica var. acida) and the country oranges (Citrus aurantium); of these the Batavian forms the most noteworthy. This variety is found to come up well in almost all soils such as sandy or red loams and typical red soils. It requires timely irrigation and the importance is well evidenced by the presence of large wells in these gardens. Good drainage also appears to be essential, since water-logged condi- tions affect the tap root. The trees are planted 20 to 35 ft. apart. They begin to bear after seven years and normal bearing begins after ten years. Various manures are applied, such as tank and canal silt and horse and cattle manure. This is done during December, and irrigations are given immediately afterwards, the idea being to induce early flowering which commences during December-January. Dur- ing the beginning of July, the fruits are ready for basketing which is done to induce good colour and early ripening. A month or a month and a half after basketing, the fruits will be ready for the market. The price of the fruits usually varies hetween Rs. 30 and Rs. 50 per 1000. each fruit selling for an anna or two. Though a paying crop. there is loss in certain years due to insect attack and as such, the fruit-grower in these parts will do well to get some knowledge of these pests and the possible methods of their control.
