Item EFFECTIVENESS OF LOCAL BIOPESTICIDES IN THE CONTROL OF DIAMONDBACK MOTH (PLUTELLA XYLOSTELLA L.) IN CABBAGE PRODUCTION IN ZANZIBAR, TANZANIA(Acta Agriculturae Slovenica Journal, 2024) Dr. Ahmed Gharib Khamis; Ali Abdulla Ali,Mwanamanga Haji Ali; Ali Seif Nassor; Mohammed Omar Hamad; Salma Omar Mohammed; Dr. Mohammed Dhamir Kombo.This experiment was conducted to determine the effectiveness of different types of local biopesticides to control diamondback moth (DBM) in cabbage production in Zanzibar. The experiment was conducted in horticulture farms at Zanzibar Agricultural Research Institute. The experiment was conducted in a randomized complete block design, with 6 treatments and a control, each of which was replicated 3 times. The water extract of the following plants were used as biopesticide which are garlic (T1), pepper (T2), clove (T3), mixture of garlic and pepper (T4), mixture of garlic and clove (T5), synthetic insecticide (T6) and a control (T0). The parameters were evaluated by conducting initial data collection (before treatment) and final data collection (after treatment). The average number of leaves affected by DBM and yield in terms of average weight (kg) of cabbage at the harvest stage were recorded. Results showed that T6 was associated with a lowest average number of affected leaves and higher yield followed by T4 , T1 and T5. Overall, garlic-treated plots had recorded higher yield compared to the non-garlic treated plots. Therefore, garlic extract as local biopesticide can effectively repel DBM. This study recommends that garlic can be used as an alternative to using synthetic chemicals to control DBM in cabbage crop.Item Community perspectives on the magnitude of Xeroderma pigmentosum and care-seeking practices in Micheweni district, Pemba: a mixed-methods crosssectional study(BMJ Open, 2024) Lucas E Matemba,1 Elizabeth H Shayo ,2 Ame Masemo,3 Nahya K Nassor,3 Mayassa S Ally,3 Judith Msovela 4Objectives To determine the community’s perception on the magnitude of Xeroderma pigmentosum (XP) disease and healthcare-seeking practices in Micheweni, Pemba in response to the public widespread information on the increased burden of the disease. Design Mixed-methods cross-sectional study. Setting Micheweni district, Pemba. Participants 211 male and female adults in the household survey, three caretakers/parents of patients with XP in the case study, 20 key community leaders/ influential people and health workers in in-depth interviews and 50 community members and other leaders in six focus groups. Results This study has revealed that XP disease exists in few families of which some of them have more than one child affected. The record review showed that there were a total of 17 patients who were diagnosed with the disease for the past 3 years, however only 10 were alive during the time of the survey. Findings from the community members revealed that several patients were believed to have XP disease and perceived causes include inheritance, food types, beliefs and other sociocultural practices. Stigma and discrimination were reported by caretakers and religious leaders. However, some cases believed to be XP were identified as other skin conditions when clinical examination was performed by the team of our researchers. There is a great confusion about XP and other skin diseases. Conclusion The study has shown that XP affects only few families, hence termed as concentrated rather than a generalised disease. Due to the rareness of the disease, majority of people in the district are unaware of the disease, hence confusing it with other skin conditions. There is a need for the government in collaboration with other stakeholders to provide educational programme to community members about the disease to address the misconception about the magnitude of the disease
