“…The analysis revealed the presence of 16 active compounds with a dominance of organophosphorus. These results confirm these of Tarnagda et al (2017) that has detected 13 actives compounds on Loumbila areas. Our results are contrary to those of Son et al (2017) who show a dominance of organochlorines in western and north region of Burkina Faso.…”

The present study consisted of evaluation of cultural practices and pesticides contamination level of tomato in some gardening sites in the region of Boucle du Mouhoun (Burkina Faso). A survey of phytosanitary practices among 30 producers was carried out at the Di and Dedougou sites. The pesticide contamination level of tomatoes collected was determined by the QuEChERS method. The survey revealed a low level of literacy among producers (60%), an increased use of pesticides without adequate protection materials, non-compliance with prescribed doses, use of unregistered pesticides (28%) and poor management of packaging. Chromatophic analysis of the samples detected 16 active substances predominantly organophosphorus (62%). 62.5% of detected compounds (Omethoate, Parathion methyl, Diazinon, Methydathion, Pyridaphethion, Pyrimiphos methyl, Alachlor, 2.4 DDT, lindane, permethrin and Imazalil) are not authorized by the CSP. Among authorized compounds, Dimethoate, Malathion, and Cypermetrin contamination levels higher than the MRLs have been observed. These results confirmed risks of environment contamination and sanitary of farmers and consumers linked to their exposure and consumption of tomatoes. Measures should be taken to raise awareness among market gardeners of good pesticide use practices and the adoption of alternative methods to pesticides to protect environment, gardeners and consumers health.

“…Concerning the management of empty pesticide containers (incinerating, discarding, burying) by farmers, the sampled farmers adopted unsafe and not eco-friendly practices, which increases the risk of environmental pollution, similar results have been reported by Tarnagda et al (2017) in Burkina Faso.…”

Pesticides are used in agriculture for the control of pests and weedy species. Unfortunately, these chemicals are a potential risk for environment contamination and human toxicity. Market gardening soils are vulnerable to human activities because of the pesticide use. The objective of this work was to make a rapid and adequate diagnosis of the conditions of pesticide use by market gardeners. Thus, a view to assess the real impact of their use on the risk of soil pollution has been established. For this purpose, interviews and questionnaires were submitted to 243 market gardeners in Port-Bouët, Songon and Bingerville. 100% of farmers use chemical pesticides on their farms. The most pesticides used are insecticides, fungicides and herbicides. 92% of farmers have a low education level and only 4.33% of them have received a good agricultural practices training. Unsafe practices such as fraudulent use of unregistered pesticides, noncompliance with recommended rates of pesticide, the use of cotton pesticides and persistent molecules have been observed. These practices increase the risk inherent of environment pollution and vegetables.

“…Selection pressure from widespread use of pyrethrum coils and insecticide aerosols in households is also likely [33, 34]. Resistance to carbamates is more difficult to explain because this class of insecticides is not used for vector control in Ouagadougou, though they are used for pest control in urban agriculture in Ouagadougou [35]. In Cameroon, deltamethrin and bendiocarb resistance was recorded in Ae .…”

BackgroundResistance to pyrethroid insecticides involving kdr mutations is widespread in Aedes aegypti (L.) (Diptera: Culicidae) and potentially could impact control efforts in endemic countries. Dengue cases had been sporadic in Burkina Faso for over a decade prior to the 2016–2017 outbreak that resulted in 15,074 suspected cases and 36 deaths, mainly in Ouagadougou. These outbreaks highlighted the lack of information on numerous aspects of the biology, behaviour and insecticide status of local dengue vector populations that are fundamental to vector control.ResultsWe investigated the insecticide resistance profiles and the kdr mutations involved in pyrethroid resistance of Ae. aegypti from Somgandé, a district of Ouagadougou. WHO bioassays revealed that the local Ae. aegypti populations were highly resistant to pyrethroids with mortalities of 15% for permethrin and 37% for deltamethrin. Resistance to carbamates was also detected with mortalities of 55% for propoxur and 90% for bendiocarb, but high mortalities (> 97%) to organophosphates (malathion and fenitrothion) indicated susceptibility. Allele-specific PCR and voltage-gated sodium channel gene sequencing showed a very high frequency (97%) of the F1534C kdr allele whilst the V1016I kdr mutation frequency was 46%. Association of dual-locus kdr mutations was detected for permethrin resistance.ConclusionWe conclude that in this locality of Burkina Faso, Ae. aegypti is resistant to pyrethroid and carbamate insecticides but remains susceptible to organophosphates, providing useful information for possible future control.
