MEETING: Annual Workshop Conference on Pulse Crops, 3rd -- New Delhi, India,
Feb 3-5, 1969
A total of 132 lines of cowpea, 104 lines of mungbean and 100 lines of
blackgram were screened for resistance against galerucid beetle, jassid
(Empoasca kerr Pruthi), aphid (Aphis craccivora K.), semi-loopers (Plusia
spp.) and leaf miner (Acrocercops spp.) during the kharif season of 1968. All
lines of each crop exhibiting resistance should be further screened in larger
plots and the most promising ones should be further tested by artificial
infestation in a screen house. [THH]

(Entomology)) (REP.MB-0649)
Five mungbean varieties were used to study the relative resistance to the
attack of beanfly, Ophiomyia phaseoli, in Rizal, the Philippines. The beanfly
attacked the mungbean plants in all stages of growth but severe damage was made
during seedling stage. The most resistant variety as indicated by the damaged
and dead plants was Mungong Tagalog with only 14.81% plant mortality. The
thickness of the pubescence and toughness of the stem of Mungong Tagalog seemed
to be the main contributing factors in rendering the plants unsuitable for
beanfly oviposition. [THH]

MEETING: Workshop [on] kharif Pulses, 7th -- Bangalore, India, Jun 5-9, 1972
Varietal susceptibility of mungbean to gram pod borer, Heliothis armigera
Hbn., was observed in two experiments. Varieties were classified as least
susceptible, moderately susceptible and highly susceptible having 0 to 15%, 16
to 40%, and above 40% damaged pods, respectively. Among ten varieties of
experiment 1, the least susceptible variety was NP 23 and highly susceptible
L-24-2 with 4.1% and 46% pod damage, respectively. Experiment 2 comprised 16
varieties. The least damaged variety was Kheda 10 with 11.36% pod damage and
the worst infested was GC 207 with 40.44%. [THH]
