186 D. d'emmerez de charmoy and s. gebert. 



Voheme [Vigna catjang) and Haricot Bean {Phaseolus vulgar e). 



Agromyza phaseoli, Coq., is such a regular pest of these plants that their 

 cultivation is almost impossible in certain localities and at certain times of the year. 



Remigia [Pelamia) repanda, F. The caterpillar feeds on the leaves of Vigna 

 catjang. 



Pea {Pisum sativum). 



Plusia orichalcea, F. The caterpillar is a minor pest of peas, doing some injury 

 to the leaves. 



Chloridea obsoleta, ¥., occurs as a leaf pest. 



All the Lycaenid butterflies mentioned under Cajamis indicus attack the pea 

 more or less. The chief pest, however, is Lampides boetica, L., which is sometimes 

 responsible for great damage. 



Pistache [Arachis hypogaea). 



The pests attacking ground-nuts are not numerous and do not cause very serious 

 damage. 



Chloridea obsoleta, F., and Plusia orichalcea, ¥., are the only two worth recording 

 as leaf pests. Ephestia cautella. Walk., attacks the fruits, and Pseudococcus 

 calceolariae, Mask., is sometimes a serious pest of the roots. 



Pumpkins, Melons, Cucumbers, etc. 



Cucarbitaceous plants suffer severely from the attacks of the fruit-flies, Dacus 

 sygmoides, Coq., and Tridacus d' emmerezi , Bezzi. 



The caterpillar of a Pyralid moth, Glyphodes indica, Snd., feeds on the tender 

 leaves and buds. It is not greatly harmful to the plant itself, but as the leaves are 

 used for human consumption, and as the caterpillars always roll themselves in the 

 leaves, they are troublesome pests. 



Aphis gossypii, Glov., is a minor pest. 



Cruciferae (Cabbage, Cauliflower, etc.). 



The Pyralid moth, Crocidolomia binotalis, Z., has proved to be a regular pest 

 of cabbage. The leaves are so badly eaten that they rot in situ and are thus rendered 

 unfit for human consumption. 



Plutella miculipennis, Curt. Late in the season the leaves of cauliflowers and 

 cabbages are badly attacked by this pest. 



Aphis hrassicae, L., occurs in abundance at the beginning of the season. Towards 

 the end its numbers are reduced, as it is preyed upon by Syrphid flies, chiefly 

 Xanthogramma pfeifferi, larvae of lace-wing flies, and by a large ladybird, Chilomenes 

 lunata. 



Artichoke. 



Two pests occur : — -The artichoke moth, Porpe hjerkandrella, Thunb., which is 

 very prevalent at times and greatly injures the foliage ; and an Aphid, Macrosiphum 

 picridis, F., which is exceedingly common on the leaves and tender parts of the 

 stem, doing serious damage. 



Tomato. 



The insect enemies of the tomato are the same as those of tobacco and need 

 not be mentioned again. It is worth recording, however, that the eel-worm, 

 Heterodera radicicola, is a regular pest and sometimes occasions great losses.
