References on Mango

Abstract : It is reported from the Chittagong area of Bangladesh by S. Ahmed, J. H. Choudhury & O. Zethner that Alstonia scholaris (which is normally found in mixed deciduous forests and has only recently been grown in nurseries and plantations for the sake of its wood) is attacked by Parotis marginata (Hmps.), which rolls and partly skeletonises the leaves, retarding the growth of the tree so much as to make it unsuitable for transplanting into forests. Notes are given on the appearance of this Pyralid and its life-cycle in the laboratory, which lasted 30-40 days at 20-25 deg C. and 80-85% R.H. In the field, larvae were present from March to October; young ones fed directly on the leaves without rolling them, and older ones formed and consumed about two leaf rolls daily. Pupation took place in the soil.From Rajasthan in India, V.S. Bhatnagar reports the finding of Amritodus (Idiocerus) atkinsoni (Leth.), a pest of mango, for the first time on the leaves of fig (Ficus carica) and ceriman (Monstera deliciosa) in the Udaipur region in 1973, as well as on the leaves and inflorescences of mango. Two periods of activity were observed, from February to April and from June to mid-August; the heaviest attacks occurred on mango in the first and on fig and ceriman in the second.From West Bengal in India, where mushroom cultivation has become of increasing importance, A. B. Mukherjee & A. K. Som-Choudhury report the occurrence of large populations of Tyrophagus putrescentiae (Schr.) on Volvaria and Agaricus spp. in the Bankura district in June-October 1968; young button mushrooms were sometimes completely destroyed. Although this mite is known as a mushroom pest in Britain [cf. RAE/A 57, 2698] and (under the name of T. lintneri (Osb.)) in the United States, in India it has so far been found only in stored products [cf. 59, 472] and soil. T. putrescentiae is also reported to cause damage to laboratory cultures of the fungi Aspergillus, Fusarium and Penicillium spp.
