“…Previously, El-Maghraby and El-Maraghy (1987) found A. flavus and A. niger comprised only 8.1 and 2.2% of the total fungi in Egyptian peanuts. With regard to Aspergillus section Circumdati group, Tripathi and Kumar (2007) found them to be present in only 12.7% of the total fungi in India. However, none of the studies in Egypt examined potential for mycotoxin production by these genera.…”

To understand the importance of mycotoxigenic fungi in Egyptian peanuts, samples from five regions (Alexandria, El-Beheira, El-Sharqiya, El-Daqahelaya in northern Egypt and Asyut, southern Egypt) in two seasons (2007, 2008) were collected. Aspergillus was consistently the most frequent genus in seeds and in-shell peanuts and was the dominant mycotoxigenic component of the mycobiota. There was no direct correlation between the moisture content of the samples and the fungal populations on peanut seeds tested from different regions. The most common species were from Aspergillus section Flavi (4.7-78.3%), Aspergillus section Nigri (9.4-52.6%) and Aspergillus section Circumdati (5.1-30.9%). In the in-shell peanut samples, the lowest populations were recorded in El-Beheira and Asyut (3.7-4.0 log10 CFU g(-1)) and the highest in Alexandria and Elsharqiya (4.1-6.0 log10 CFU g(-1)). Aspergillus section Flavi and section Nigri were the most dominant, and Aspergillus section Circumdati were only found in samples in 2008. Both qualitative (coconut cream agar) and quantitative analyses (HPLC) were used to analyse the potential mycotoxin production by strains isolated from peanuts. Of a total of 88 Aspergillus section Flavi strains examined, 95% were A. flavus based on production of aflatoxin B1 on yeast extract sucrose (YES) medium and confirmation using molecular analyses. Of 64 Aspergillus section Circumdati strains only 28% produced ochratoxin A (OTA), and were identified as A. westerdijkiae. No Aspergillus section Nigri strains produced OTA, and they were identified as A. niger (uniseriate). The presence of these toxigenic fungi indicates that there is a potential risk of mycotoxin contamination in Egyptian peanuts and suggests that problems can arise from contamination with both aflatoxins and perhaps also OTA.

“…Moreover, because of the lesser fungal association in EO fumigated sets, the fungal cells used most of the available energy to sustain viability, not for toxin production as has been emphasized by Burt (2004). Although, different EOs have been previously tested for their in vivo fungitoxicity of food commodities like cereals, pulses, spices, fruits and vegetables (Varma and Dubey, 2001;Tripathi and Dubey, 2004;Tripathi and Kumar, 2007;Prakash et al, 2012c) the in vivo fungitoxicity of ajowan EO against fungal as well as aflatoxin contamination in food preservation has been tested for the first time in the present study. The application of EO in food preservation would be one of the economically viable and effective stratagies due to its volatility and penetration in food systems.…”

“…Samarasekera et al (2004) reported that the isolated compounds skimmiarepins A and C from the ethyl acetate extracts of the stem bark of the same plant exhibited moderate insecticidal activity against Phaedon cochleariae and Musca domestica. The essential oil showed 40% repellency at 0.02 ml against Trogoderma granarium (Tripathi and Kumar 2007), reported as a fungitoxicity against Aspergillus flavus (Kumar et al 2008). Earlier scientists have reported that the essential oil obtained from V. negundo leaves shows that repellency ranged from 1 to 3 h (Hebbalkar et al 1992).…”

The purpose of the present study was to assess the effect of leaf hexane and chloroform extracts of Aegle marmelos, Andrographis lineata, Andrographis paniculata, Cocculus hirsutus, Eclipta prostrata, and Tagetes erecta on repellent, ovicidal, and oviposition-deterrent activities against Culex tritaeniorhynchus Giles (Diptera: Culicidae). The repellent action of the plant extracts tested varied depending on the plant species, part, solvent used in extraction, and the extract dose. The hexane extract of A. paniculata was more effective in exhibiting the repellent action against the mosquito as compared with A. lineata extract. Complete protections for 150 min were found in hexane extract of A. paniculata at 500 ppm against mosquito bites. Mean percent hatchability of the ovicidal activity was observed 24 h after treatment. The percent hatchability was inversely proportional to the concentration of extract and directly proportional to the eggs. No hatchability was observed with hexane, and chloroform extracts of A. lineata, A. paniculata, and hexane extract of T. erecta were exerted at 1,000 ppm. The percentage of effective oviposition repellency were 95.90, 94.75, 95.04, 90.58, 87.93, 87.14, 94.82, 95.71, 92.26, 90.58, 83.35, and 78.16 at 500 ppm, and the lowest repellency was 69.93, 53.06, 64.81, 70.06, 51.82, 54.54, 48.31, 66.71, 68.82, 61.85, 34.84, and 39.53 at 31.25 ppm in hexane and chloroform extracts of A. marmelos, A. lineata, A. paniculata, C. hirsutus, E. prostrata, and T. erecta, respectively. The oviposition activity index values revealed that the solvent plant extracts have deterrent effect, and they caused a remarkable negative response resulting in oviposition of very few eggs. These results clearly reveal that the hexane extracts of A. marmelos and A. paniculata served as a potential repellent, ovicidal, and oviposition deterrent against Japanese encephalitis vector, C. tritaeniorhynchus.
