feature caused by thrips, Megalurothrips distalis (Karny). Eleven insecticides
were tested in field trials for the control of thrips in 1982-1984. All the
treatments were significantly better in controlling the thrips, reducing flower
shedding, increasing the pod numbers and grain yield, in comparison with the
control. Increases in yield compared with the control during trials ranged from
85 to 89% (1982), 26 to 96% (1983) and 5 to 194% (1984). Dimethoate gave the
highest increases in yield and profit followed by monocrotophos and endosulfan.

Different doses of malathion, dimethoate, oxydemeton methyl and
phosphamidon were tested in five field trials for controlling the thrips,
Megalurothrips distalis Karny. Higher doses of malathion at 125 G and the rest
of the insecticides at 75 g a.l./ha were significantly more effective in
controlling thrips and gave substantially higher yields. Dimethoate fetched the
maximum net profit of Rs. 2033/ha followed by phosphamidon (Rs. 1731/ha)
malathion (Rs. 1662/ha) and oxydemeton methyl (Rs. 1661/ha). [AS/THHI

stored mung. SCIENCE AND CULTURE, v.18(7):333. [En] (REP.MB-1114)
Laboratory trials were carried out for controlling the bruchid pests of
stored mungbean with both insecticides and vegetable oils. DDT and benzene
hexachloride (1:100,000 parts by weight), copper carbonate (1:200), and sodium
fluosilicate (1:1600) were quite successful in controlling the bruchids. All
the vegetable oils, namely, castor, coconut and mustard oils at the rate of 225
g per 40 kg grains were very effective. [THH]

unmilled pulse (mung). SCIENCE AND CULTURE, v.9:305. [En] (REP.MB-0112)
In a laboratory rearing trial with Bruchus analis, the bruchid grubs were
unable to complete their life cycle in broken grains of pulses. The reasons are
first; the moisture content gets reduced when the grains are broken after
milling and second; there is not enough space for pupation in the broken halves
as a result of which most of the bruchid grubs die without reaching the adult
stage. [THI]
