for controlling storage insects. BIOTROP NEWSLETTER, no.45:3. [En] (A:PS)
Turmeric powder was tested for controlling the storage pest Callosobruchus
maculatus on mungbean in Indonesia. The adult females were more tolerant than
adult males. LD 50 and LD 99.99 for males were 0.01 ppm and 1.5 ppm,
respectively, and for females 0.05 ppm and 4.1 ppm. Turmeric extract was 5-10
times less toxic to the pest than synthetic insecticides and was 100-1000 times
more toxic than other insecticides of plant origin such as neem extract or
black pepper. [THH]

On seeds of mungbean [Vigna radiata (L) Wilczekj, treated with groundnut
oil (8 ml/kg), the density eggs laid by C. chinensis was reduced by 90%. 90% of
the eggs, however, affixed on oil treated seeds died within 48 h as a result of
coagulation of protoplasmic contents in the embryo. In the remaining 10% eggs,
the initiation of embryonic development could be observed upto certain extent
but the embryo died thereafter. [AS]

[JaJ [En Abst] (REP.MB-2704)
Legume seeds (25 ml) were placed in a test tube (2.2 cm in diameter) and
five of the adults were released in the tube. After all the adults had died,
the number of eggs deposited on the surface of seeds were counted. This test
was done with seeds of four species having different sizes in descending order:
Pisum sativum, large Vigna angularis, V. unguiculata, normal V. angularis,
small V. radiata. In P. sativum both species of beetle (C. chinensis and C.
maculatus) distributed their eggs evenly on each seed. While in the pulses
having relatively smaller size of seed, C. maculatus could deposit their eggs
much deeper than C. chinensis. The measurement of the length, width and
thickness of the body indicated that C. maculatus had apparently a slimmer and
flatter body than C. chinensis. This might enable C. maculatus to creep into
the grain pile more easily than C. chinensis. [AS]
