More than 3000 mungbean accessions were screened for insect resistance in
the field. Fifty seeds of each variety were sown as a single row in a 5m x
0.75m plot. Selected resistant accessions were then sent to Thailand,
Philippines and Indonesia where the screening was done to find varieties
resistant to local strains. Selected beanfly resistant and susceptible
varieties were examined for resistant mechanism in the field and in the
greenhouse. The results showed that the mechanism of resistance to insect was
non-preference. A positive correlation was found between the thickness of
mungbean leaf and beanfly infection rate (r=0.8165). This implied that
beanflies prefer to eat or lay eggs in thick leaf varieties. Other mechanism
will need further study. [PLH/NSTj

Nine insecticides were tested for controlling beanfly on soybean and
mungbean at AVRDC. The insecticides of EC, SCW, SP, WP formulation were applied
3 times after germination. The granular insecticides were applied once at
sowing. Carbofuran 3% G (2.0 kg a.i./ha), Oxamyl 24% LC (0.25 kg a.i./ha),
phorate 10% G (2.0 kg a.i./ha), carbofuran 40.64% F (1.0 kg a.i./ha),
triazophos 40% EC (0.25 kg a.i./ha), and omethoate 50% LC (0.25 kg a.i./ha)
were effective in controlling the pest. [THH]

Beanflies are pests of various important food legumes including mungbean,
soybean, adzuki bean, lima bean, snap bean, cowpea and asparagus bean. Field
plot evaluations of insecticides for their control were carried out in ten
square meter plots. Each insecticide tested was applied to four replicated
plots in a RCB experimental field design. For each crop planting, nine
insecticides and one control were evaluated. Granular formulated insecticides
were applied by hand with the amount for each ro. or the plot being previously
weighed. Emulsifiable and wettable powder formulations were applied with 10 lb.
air pressure sprayers calibrated with a stopwatch. For the emulsifiable or
wettable powder formulated insecticides, 500 ml spray were applied per plot.
Methods of control evaluation were based on the dissection and count of the
number of larvae and pupae as well as the number of damaged plants in a thirty
plant sample. Under the conditions of three field tests in which 27
insecticides were evaluated, the most effective were carbofuran, triazophos,
mephosfolan, diazinon, DDT and disulfoton and aldicarb. [AS]
