The topical treatment given to freshly emerged (0–1-day-old) male and female adults ofBactrocera cucurbitae (Coquillett), a serious pest of cucurbit crops in tropical countries, with 25, 125, 625 and 3125 ppm concentrations of gibberellic
acid (GA3), indole-3-acetic acid (IAA), kinetin and coumarin showed a significant adverse influence on the reproductive potential of
this fruit fly. The assessment for reproductive potential was made on the basis of reduction in fecundity and fertility of
laid eggs and measured as sterility in females and shortening of the longevity,i.e. ovipositional phase. The strongest influence was with kinetin, followed closely by coumarin, then GA3 and lastly with IAA treatments. It was concluded that although these compounds demonstrate their activities differently in
plants and might be following a different mode of action in insects, they ultimately influence the reproductive potential
of this insect. 相似文献

In August 2015, a rabies outbreak occurred in bovines in a Punjab village, India; subsequently, a farmer in the same village died of rabies in October 2015. We surveyed farmers to describe the outbreak, the demographics and rabies prophylaxis administered to householders on case farms, and farmers’ knowledge of rabies prevention and treatment. We used multiple correspondence analysis to guide investigation of associations between demographics, farm status and rabies knowledge, attitudes and practices. The number of affected bovines was unusually high; 15 cattle and buffalo died on 13 smallholder farms (attack rate 4%). Post‐exposure vaccinations were administered to 24 people (median 2 doses). Affected farms had significantly larger households and were more likely to keep their livestock outside (therefore, accessible by stray dogs), suggesting that the impact of the outbreak was disproportionally borne by households of lower socio‐economic status. Primary sources of rabies information were friends and neighbours, not health authorities or media. Women who had not received formal education were less likely to have heard of rabies. Although case farm participants were more likely to have heard about rabies from a veterinarian, their knowledge and practices to prevent rabies did not reflect the level expected considering their contact with a health professional; they were more likely to believe that traditional remedies prevent rabies and less likely to tell their children to avoid playing with stray dogs than participants from other farms. This study highlights knowledge dissemination disparities that, if typical of rural locations, could obstruct attempts to eliminate canine‐mediated human rabies in India. Therefore, understanding the pervasiveness and influence of traditional medical beliefs on treatment‐seeking behaviour, communication structures within villages and the impact of local practices such as carcass disposal on dog populations will be essential to ensure that rabies control strategies are effective in rural India. 相似文献

A prevalence study was contemplated to determine the prevalence of Cryptosporidium spp. in dairy farms in Punjab, India. The cryptosporidium oocysts were detected from 50 and 25.68% from 80 diarrheic and 74 non-diarrheic animals, respectively. Both shedding and intensity of shedding were significant in calves with diarrhea. The Cryptosporidium spp. appears to be common in dairy calves and an important contributor of calf diarrhea in the Punjab province. The prevalence of the infection peaked in young calves between 0 and 30 days in both the diarrheic and non-diarrheic groups (86.4 and 66.6%, respectively). The percentage distribution of positive samples, with reference to age groups of diarrheic and non-diarrheic animals was negatively correlated with increase in age. High mortality rate and case fatality rate of 35.2 and 44.4% were observed in young calves between 0 and 30 days of age. 相似文献
