Seasonal Dynamic of the Fall Armyworm, Spodoptera frugiperda (J.E Smith, 1797) (Lepidoptera: Noctuidae) on Maize Crop in the Sub-Sudanese Zone of Côte d’Ivoire

Advances in Entomology 2024年第2期12卷 78-92页

作者： stéphanie Manuela Klamansoni Akissi Konan Laya Kansaye Nondenot Roi Louis Aboua West Africa Science Service Centre on Climate Change and Land Used (WASCAL) Abidjan C&#244te d&#8217Ivoire Rural Polytechnic Institute of training and Applied Research Katibougou Mali Department of Entomology and Ecosystem Management F&#233lix Houphou&#235t-Boigny University Abidjan C&#244te d&#8217Ivoire

In Côte d’Ivoire, maize (Zea mays L) is the second most cultivated cereal after rice. Since the first report of Spodoptera frugiperda in Côte d’Ivoire, maize production in the northern regions has been affected resulting in maize production losses. this study aims to study the seasonal dynamic of Spodoptera frugiperda in maize fields in the sub-Sudanese zone, main zone of maize cultivation in Côte d’Ivoire. the study was done using pheromone trap lures. the results revealed a variation in the moth population at various growth stages during rainy and dry seasons. Notably, the highest numbers of moths were consistently trapped during the whorl stage with counts ranging from 131 ± 35.7 during the rainy season to 70.6 ± 15.01 in the dry season. the lowest numbers of moths were observed during pod maturation, with counts ranging from 30.3 ± 13.05 during the rainy season to 11.7 ± 3.05 in the dry season. Between the 7th and 21st days after sowing, the count of moths displayed a consistent upward trajectory, reaching 188 moths during the rainy season. the damages were particularly observed at whorl stage. the relationship between the numbers of moths and some climatic variables revealed a negative correlation between moths numbers and rainfall (r= −0.44) and relative humidity (r= −0.684). In contrast, there were positive relationships with temperature (r = 0.16), highlighting the significant impact of temperature changes on moth population dynamics. the research highlights the need for integrated pest management strategies that consider climatic factors and growth stages of maize to mitigate the impact of this insect pest on maize.

Cardiovascular diseases are serious pathologies that affect an increasing number of people. Several preventive measures are generally used, including supplementing of oils in foods. Our objective was to compare the effects of tetracarpidum conophorum oil (tC) and corn oil (CO) on serum lipid profiles of normal male rats. 42 Wistar rats were divided into 7 groups. Diets included tC oil (groups tC5, tC10 and tC20) and corn oil (groups CO5, CO10 and CO20) in proportions of 5%, 10% and 20%, with a control group (t). After 5 weeks of feeding, several parameters were measured during and after the study, including body weight, food intake and organ weights (kidney, liver and fat). Lipid profiles (total cholesterol, tG, HDL and LDL), glucose and protein levels were measured in the serum. the increase in body mass was inversely proportional to the amount of oil in the food. the decrease in body mass and adiposomatic index of group tC10 was significant (p th the other groups. the lowest glycaemia (64.17 ± 5.14 mg/dl) was noted with the diet containing 20% tC oil. A significant reduction in total cholesterol, LDL fraction and blood triglycerides was observed in the groups supplemented with tC and corn oils compared to controls. Results were also more beneficial for the tC10 group. HDL-cholesterol levels were significantly higher (p the oil-supplemented groups than in the control group. Castelli’s risk indices decrease significantly (p th increasing oil content for tC. the oils had no impact on blood protein contents. One can conclude that a diet containing 10% crude oil from tC kernels could prevent or alleviate cardiovascular diseases and glycemia.

Background: Breast cancer is the dominant cancer in women in both developed and developing countries. the objective of this study was to assess the knowledge, attitudes, practices and factors associated with early breast cancer screening among women in the Municipality of Abomey-Calavi in Benin. Methods: this was a cross-sectional, descriptive, analytical study with prospective data collection from October 1 to 8, 2018, involving 1740 women in the Municipality of Abomey-Calavi, aged 18 years or older and selected by WHO four-stage random cluster sampling. Consenting women who were mentally competent, 18 years of age or older at the time of the survey, and residing continuously in the Municipality of Abomey-Calavi for the last six months prior to the survey were included. On the other hand, women who belonged to a breast cancer prevention service, women in whom secondary screening was noted, or non-consenting women were not included. the initial minimum size was estimated by the Schwartz formula with a cluster effect of k = 2. Information was collected by questionnaire survey, entered with Epidata 3.1. Fr and analyzed with R studio 3.5.1. software. Results: the mean age of the women surveyed was 32.0 ± 11.5 years with a range of 18 and 71 years. Regarding knowledge, the clinical manifestation known by the majority of women was the presence of a nodule (68.50%). In the series, 1308 (75.17%) declared having heard about breast cancer once before, either on the radio, television or from friends and 726 (55.50%) had heard about breast cancer screening. Five hundred and twelve (70.52%) of the 726 who had heard of breast cancer said they knew that breast cancer could be screened earlier. Breast self-examination was the most cited screening method (67.58%). the disease is of natural origin according to 37.84% of them. Regarding attitudes and practices, the prevalence of early breast cancer screening was 12.93%, of which 11.67% declared that they had checked themselves to kno
