oviposition and development of Callosobruchus maculatus (Fab.) on various
stored pulses. BULLETIN OF GRAIN TECHNOLOGY, v.12(2):113-116. [En] [En Abst]
(REP.MB-2855)
The oviposition and develoiatent of Callosobruchus maculatus (Fab.) on a few
stored pulses were studied. The beetle seemed to be guided in its oviposition
on preferences by smoothness of surface of seed coat and size of the grains.
Oil treated and dehusked grain were not much preferred for oviposition. Soybean
does not seem to be an ideal host for the development of this pest. The
soybean, chicken pea and pea were more preferred for oviposition. The
development of the larvae was not found better on those grain which were
preferred by this beetle for oviposition. [AS]

the pupae of stored product insects. BULLETIN OF GRAIN TECHNOLOGY,
v.12(1):32-35. [En] [En Abst] (REP.MB-2225)
Studies on the pupal microflora of Sitophilu. oryzae, L., Tribolium
castaneum, Herbst; Trogoderma granarium, Everts, Callosobruchus chinensis,
Corcyra cephalonica St., and Ephestia cautella Walker, have been conducted. It
was found that none of the pupae were microbiologically sterile. It is
concluded that the pupa of stored product insects screened act as a carrier of
several toxlgenic and saprophytic food spoilage microbes from its larval stage
to the freshly emerging adults. [AS'

infestation. PHILIPPINE ENTOMOLOGIST, v.2(6):399-408. [En] [En Abst]
(REP .MB-2553)
The oviposition preference and survival of Callosobruchus chinensis (Linn.)
on mungbean pods of different stages of maturity were observed. The green stage
was least preferred for oviposition, with few surviving eggs, larvae and plenty
of adults; the black stage was preferred and with small number of trapped
adults. Early harvesting is suggested to minimize infestation. The resistance
of 20 varieties and 46 accessions of mungbean against C. chinensis (Linn.) was
also evaluated. None of the varieties was resistant to oviposition, but
resistance to larval survival was evident with EG Glabrous, EGMG 4 and EGMG 7.
The mungbean accession numbers 23, 25 and 325 of UPCA were resistant to
oviposition and larval survival. [AS]

The almond moth, Ephestia cautella (Walker) was reared on individual food
material at 30 [plus or minus] i C, 80 [plus or minusj 5 % RH and 12 hour
light: 12 hour dark photoperiod. Food materials used for this experiment
included wheat (Triticum aestivum L.), maize (Zea mays L.), bajra (Pennisetum
typhoideum Pers.), mungbean (Vigna radiata Wilczek), blackgram (V. mungo
Hepper), red gram [Cajanus cajan (L) Mill.sp.], lentil (Lens esculenta Moench.),
soybean [Glycine max (L) Merril], bengal gram (Cicer arietinum L.), French bean
