The process of moulding caused by the fungi: <i>Aspergillus repens</i> (Cda.) De Bart, <i>Aspergillus flavus</i> Link, <i>Aspergillus ochraceus</i> Wilhelm, <i>Penicillium expansum (Link) Thom, VPenicillium commune</i> Thom and <i>Penicillum spinulosum</i> Tom influenced the decrease in soluble carbohydrate content with the simulataneous increase in the percentage of specific protein. It had an effect on the deterioration of technological and taste values of raw tabacco.

The cashew stem girdler, Analeptes trifasciata, is a major insect pest of cashew in Nigeria causing economic damage in cashew plantations even at low density. In this study, newly emerged adults of A. trifasciata reared from field-infested cashew stems were collected from the rearing cages, sexed, and dissected to reveal the internal structures of the insects. The gut was excised and separated into the foregut, midgut, and hindgut. The dissected gut compartments were blotted dry by sandwiching in sterile Whatman No. 1 (150 mm) filter paper for a minute. The inoculated gut parts showed the presence of eight fungi flora, namely, Aspergillus repens, Trichoderma spp., Fusarium verticillioides, Lasiodiplodia theobromae, yeast, Aspergillus niger, Fusarium spp., and Rhizopus stolonifer. The frequencies of occurrence of bacteria in the gut compartments of A. trifasciata were Enterobacter spp.: 83.33%; Escherichia coli and Streptococcus spp.: 55.56% each; Staphylococcus spp.: 44.44%; Klebsiella pneumonia: 50% and Salmonella shigella: 11.11%, while each of Serratia marceascea, Pseudomonas spp., and Micrococcus lutea had 5.56% occurrence. The occurrence of mycoflora and microbiota species varied in the gut compartments of A. trifasciata, indicating the role of these microorganisms in metabolic and other bioprocesses of A. trifasciata during digestion and synthesis of complex food substances from the cashew stem substrate. This study would provide basic information for enzymatic studies of A. trifasciata with a view to developing an integrated pest management (IPM) protocol for managing the pest in cashew plantations.

Aspergillus Repens

An emended description of Sphaeronaemella fimicola Marchal refers this species to its proper taxonomic position among the Hypocreaceae, with both perfect and imperfect stages very similar to those of S. helvellae Karsten as described by Seeler. The species, found in nature on dung of various herbivorous animals (rabbit, deer, and cow), is culturable, growing more consistently on V-8 vegetable juice agar than on other media tried, most vigorously in association with other fungi like Aspergillus repens or Microascus sordidus, or with addition of filter-sterilized Czapek's broth in which A. repens had been grown. Fruiting in culture has been erratic; only early transfers from isolations made from field material yielded mature perithecia in pure culture, and then only on V-8 agar; later transfers fruited only in intimate contact with the mycelia of the other two fungi mentioned.

AbstractFIue-cured tobacco damaged by species of Aspergillus from commerciaI and experimental sources was shredded and made into cigarettes. Paired samples of nondamaged tobaccos served as controls. Subsamples of cigarettes were analysed for viable fungal propagules/g, 39 organic and inorganic compounds in the smoke and smoke condensates, and taste preference. PrincipaI fungi associated with leaves and shreds of mold-damaged tobacco were Aspergillus repens, A. ruber, and A. niger. Except for the originaI differences in the nicotine content and in the tar, there were no significant differences in total particulate matter nor in the amount of specific vapour phase components measured in the smoke from cigarettes made with mold-damaged and nondamaged tobaccos. Smoke panelists distinguished between cigarettes made with mold-damaged and nondamaged tobaccos and preferred cigarettes made with the latter. Viable fungus spores passed through the tobacco cylinder from lighted and nonlighted cigarettes. These data suggest the use of mold-damaged tobacco in cigarette manufacturing is to be avoided because of off-flavours and because the fungi isolated are common allergens to the respiratory tract of humans
