Mango (Mangifera indica L.) is an important fruit crop in Nigeria. It is a source of essential vitamins and is also cultivated for its nutritional, medicinal and industrial uses. Fruit flies infest various commercial fruit crops and cause economic damage. Mass trapping and male annihilation technique (MAT) has been the most useful and common means of controlling fruit flies with special focus on Bactrocera dorsalis Hendel (Diptera: Tephritidae) on mangoes. The study evaluated the effectiveness of four types of parapheromones namely, methyl eugenol (liquid and solid forms), cuelure, terpinyl acetate and trimedlure for mass trapping of fruit flies on Mango. Modified Lynfield traps containing the parapheromones were randomly set on the mango orchards in three replicates in Nigeria Horticultural Research Institute (NIHORT) orchard, Okigwe, Imo state, Southeast Nigeria. This study was conducted during the mango fruiting period of 2019 season, when the density of fruit flies peaked. Effect of parapheromones on mean number of damaged dropped fruits was also evaluated. The mean population of B. dorsalis and Ceratitis cosyra was significantly higher (P>0.05) in liquid methyl eugenol traps when compared to other parapheromones. Bactrocera dorsalis recorded more than 90% of the fruit flies that were trapped especially in the first 3 weeks of trapping. In orchard I, Liquid methyl eugenol significantly (P<0.05) trapped highest number of B. dorsalis (270.20) in week I and similar trends were observed in orchard II. There was steady decline in damaged dropped mango fruits as the study progressed (Fig. 1 and 2). Use of liquid methyl eugenol was most effective in trapping B. dorsalis and C. cosyra, and it can be incorporated in Integrated Pest Management (IPM) programmes for the control of fruit flies.

Synanthedon myopaeformis (Borkhausen, 1789) (Lepidoptera: Sesiidae) is a prominent pest of commercial apple orchards in Europe. the sex pheromones of S. myopaeformis and food attractants based on apple juice, beer and red wine were evaluated as tools for monitoring and control the populations of S. myopaeformis in apple orchards in the Czech Republic. For monitoring S. myopaeformis flight activity, trap designs were also evaluated, and the results indicated that wing traps were more suitable than delta traps because of their high efficacy even at low population densities of S. myopaeformis. The flight activity patterns of S. myopaeformis showed high intrapopulation variability and variability between years. The use of pheromones as a mating disruption technique led to a decrease of tree injury in comparison to untreated controls during the three years of the experiment. The reduction of the number of S. myopaeformis larvae per tree on a 14-ha plot treated subjected to the mating disruption technique reached 56 % in the third year of the experiment. In the three-year experiment using food attractants for the mass trapping of S. myopaeformis, catches of S. myopaeformis in traps using a combination of beer and apple juice (50:50) at a density of 4 traps/ha on a 4-ha plot increased more than 4-fold.

The global incidence of cancer is rising, and low-income and lower-middle-income countries have the worst figures. However, knowledge of cervical cancer prevention and cervical cancer screening practices remains poor in these regions. This study assessed the concept of health literacy as a potential determinant of knowledge of cervical cancer prevention and screening practices among female undergraduates. A descriptive cross-sectional study was conducted among 385 female undergraduates at a university in southwest Nigeria. A validated questionnaire composed of subscales on nine components of health literacy, knowledge of cervical cancer prevention, and cervical cancer screening practices was used for data collection. The majority of the respondents obtained a high score on most of the components of health literacy and 66% had good knowledge of cervical cancer prevention. Only 11% demonstrated good practices of Pap smear testing. Of all the components of health literacy, “feeling understood and supported by healthcare providers” (OR = 0.075; 95% CI [0.036–0.115]; p = 0.015) and “understanding health information well enough to know what to do” (OR = 0.055; 95% CI [0.006–0.104]; p = 0.029) were significantly associated with knowledge of cervical cancer prevention. Out of the major challenges related to cervical cancer screening among undergraduates, the feeling of being at risk (OR = 4.71; p < 0.05) and uncomfortable experiences from past screening (OR = 0.12; p < 0.05) were significantly associated with going for cervical cancer screening. The study concluded that levels of health literacy influenced knowledge of cervical cancer prevention among female undergraduates, but it did not affect their engagement in cervical cancer screening practices.

This article concerns the study examining the use of collaborative technologies (CTs) for the acquisition, creation, sharing, transfer, and retention of knowledge by therapy team members (TTMs) in psychiatric hospitals, and the determinants of the use of CTs as well as how they relate to knowledge management (KM) practices. The skills of the TTMs in the use of CTs were also investigated. Carried out within the positivist and constructivist paradigms, a sample survey was conducted among TTMs from two purposively selected psychiatric hospitals in Southwest Nigeria. Quantitative data was collected from self-administered questionnaires completed by 283 TTMs and was analysed using the Statistical Package for Social Sciences (SPSS) 22. Qualitative data was collected from interviews conducted with four heads of departments. The study showed that the TTMs in the relevant hospitals used 26 different CTs for knowledge acquisition, creation, sharing, transfer, and retention. The largest proportion (84.5%) of the respondents confirmed that skill in the use of CTs determined the use of CTs for KM practices. More than half (54.3%) of the TTMs were highly skilled in the use of CTs for KM practices. The findings suggested that the respondents were positively inclined towards the use of CTs and that they were involved in the use of various CTs to facilitate KM practices and processes. It was found that task interdependence was characteristic of the TTMs’ work in the selected psychiatric hospitals, and that, to benefit from the potential advantages of task interdependence and to effectively employ CTs in operations and processes, TTMs’ skills in the use of CTs should be developed. In addition, professional ties among experts in different fields of specialisation should be encouraged.
