or thinly ; Eitgnamptus marginatus, the adult weevil being most active- 

 on mango trees in July and August and the grubs resting in the soil 

 from September to March and April ; Attagenus piceiis, the life-cycle 

 of which takes from 1-3 years to complete ; Melittm eurytion, the 

 caterpillar of which bores and causes a swelling in the stem of Tricho- 

 santhes dioica and other Cucurbitaceous plants in the rains, and passes 

 the rest of the year in the larval stage inside a very stiff cocoon ; 

 Cosmopteryx mmiipukms, a Lepidopterous miner in bean leaves, which 

 rests in the larval stage from about November to July ; a Eurytomid 

 grub in apricot seed, which probably rests inside the seed for two years 

 in some cases, though most individuals emerge as adults after one year ; 

 an Elaterid beetle, Agrypnus fuscipes, the life-cycle of which seems to 

 take 3 to 4 years ; Ancylolomia chrysographella, which has several 

 broods, each cycle taking about a month and hibernating in the 

 caterpillar stage from November till Ma'rch or April ; Aspongopus 

 brunnens, a bug which causes severe damage to pumpkin plants ; 

 Massepha absolutalis, a Pyralid rolling bamboo leaves, which rests iiL 

 the larval stage in winter ; Pempheres affinis (cotton- stem weevil),, 

 which has been found to breed in a new food-plant, Triumfetta sp., 

 one of the Tiliaceae ; and Lampides (Polyommatus) baetica, which is a 

 pest of the flowers of Butea froiidosa. 



Grain storage experiments showed that Rhizopertha dominica cannot 

 breed where the air has free access, but under close storage conditions 

 it can do much more damage to wheat and in a shorter time than 

 Calandra oryzae. Loss due to the latter may be reduced to a minimum 

 by frequently exposing the grain to air and hght when practicable. 

 Based on this, a new method of outdoor storage in granaries made 

 entirely of straw is being tested, as is also the method of storage under 

 sand. Keeping the seeds covered with sand, coarse or fine, has given 

 the best results against Bruchus chinensis, which breeds in the larger 

 varieties of peas, Pisum sativum, Cajanus indicus, lentils, Lathyrus 

 sativus, Phaseolus radiatus and P. miingo, Vigna catjang, and Viciafaba, 

 causing serious damage. The small pea, Pisum arvense, is not 

 injured by this pest when stored, but in the field it is infested by 

 B. qffinis. Tribolium castaneum is commonly associated with Rhizo- 

 pertha dominica in stored wheat and rice, as is also Tenebroides 

 mauritanicus with Calandra oryzae, on which weevils the adult beetles 

 prey. The expectation that this insect might therefore exercise a 

 natural control has not been fulfilled, since the adults appear and 

 oviposit in July- August, passing the rest of the year in the larval stage. 

 During this time they do not attack the weevils, but bore into wheat 

 and rice grains, the chief damage by the weevils occurring simul- 

 taneously, while at other times they do not occur in sufficient numbers 

 to act as a check. 



Bagrada picta in an experimental plot of mustard was entirely 

 checked by spraying with fish-oil resin soap at a strength of 1 lb. in 

 4 gals, water, which killed even the adult bugs. Eesearch with the 

 object of finding insects which could be utilised as checks on the growth 

 of Lantana indicated three possible ones, viz. : — Platyptilia pusilli- 

 daciyla, already widely distributed in India and Burma, being one of 

 the insects imported from Mexico into Hawaii ; an apparently new- 

 Eucosmid moth ; and a Cecidomyiid fly.
