The effect of Capsicum annuum and Strophantus hispidus formulations was evaluated on Diachasmimorpha longicaudata. The formulations were obtained from the crude total extracts of C. annuum;S. hispidus and the adjuvant previously developed. The formulations were prepared according to three concentrations of extracts of each plant species (low, medium and high). These concentrations were calculated on the basis of 1.5 mg/mL of each formulation causing 18% and 15% mortality respectively in Ceratitis cosyra within 72 h. The effect of the formulations on D. longicaudata was tested using a Fisher block design with 8 treatments (C. annuum (3.75;7.5;12.5 g/L);S. hispidus (4.5;9;15 g/L);Success bait 2.4 g/L;control) and 5 replicates. For each formulation, 1.5 mL was poured into a vial containing 0.25 g of cotton. Then 20 adults of the parasitoid were added and the whole was covered with muslin and held in place with rubber bands. The parasitoids were examined after 24 and 72 hours, and those that did not react to the touch of a fine brush were considered dead. The results showed a difference between the treatments. After 24 hours of exposure, the parasitoid showed high mortality at the S. hispidus concentrations (15 g/L;4.5 g/L) followed by the Success bait. These concentrations resulted in mortality rates of 22.50% for S. hispidus and 20.50% for Success bait. After 72 h, low parasitoid mortality (35.81%) was obtained with 3.75 g/L C. annuum, but high mortality was observed with S. hispidus (59.95%;64.20%;57.15%) and Success bait (54.80%). The use of C. annuum formulations at 3.75 g/L could be recommended for conserving D. longicaudata in the nature.

Heterogeneous tunable Ⅲ-Ⅴ-on-silicon-nitride mode-locked laser emitting wide optical spectra

We demonstrate a Ⅲ-Ⅴ-on-silicon-nitride mode-locked laser through the heterogeneous integration of a semiconductor optical amplifier on a passive silicon-nitride cavity using the technique of micro-transfer printing. In the initial phase of our study, we focus on optimizing the lasing wavelength to be centered at 1550 nm. This optimization is achieved by conducting experiments with 27 mode-locked lasers, each incorporating optical amplifiers featuring distinct multiple-quantum-well photoluminescence values. Subsequently we present a comprehensive study investigating the behavior of the mode-locking regime when the electrical driving parameters are varied. Specifically, we explore the impact of the gain voltage and saturable absorber current on the locking stability of a tunable mode-locked laser. By manipulating these parameters, we demonstrate the precise control of the optical spectrum across a wide range of wavelengths spanning from 1530 to 1580 nm. Furthermore, we implement an optimization approach based on a Monte Carlo analysis aimed at enhancing the mode overlap within the gain region. This adjustment enables the achievement of a laser emitting a 23-nm-wide spectrum while maintaining a defined 10 dB bandwidth for a pulse repetition rate of 3 GHz.

The Entomological Efficacy of Piperonyl Butoxide (PBO) Combined with a Pyrethroid in Insecticide-Treated Nets for Malaria Prevention: A Village-Based Cohort Study Prior to Large-Scale Deployment of New Generation Mosquito Nets in Burkina Faso

Advances in Entomology 2024年第3期12卷 224-248页

作者： Aristide S. Hien Samina Maiga Koama Bayili Adissa Y. Ouattara Dieudonné D. Soma Richard Bationo Georges Benson Meda delphine O. Karama Tiecoura Camara Georges Anicet Ouedraogo Roch K. Dabiré Abdoulaye Diabaté Malaria and Neglected Tropical Disease Department Institut de Recherche en Sciences de la Sant (IRSS) Bobo-Dioulasso Burkina Faso Sciences and Techniques Department Institut du Developpement Rural Universit Nazi Boni Bobo-Dioulasso Burkina Faso Vector Control Department Permanent Secretariat for Malaria Elimination Ouagadougou Burkina Faso

The efficacy of insecticide-treated nets (ITNs) is increasingly compromised by the prevalence of malaria vectors resistant to pyrethroids. In response to this issue, a new generation of ITNs has been developed that incorporate synergistic components, such as piperonyl butoxide (PBO). The purpose of this study is to provide entomological evidence for the efficacy of a PBO-based ITN brand at the village level, serving as a basis for decision-making before large-scale net deployment. During the high malaria transmission period, ITNs were distributed in each group and vector sampling was conducted biweekly in selected households. Bionomic data were collected to assess the resistance of wild An. gambiae populations to various chemical insecticides. There was a significant disparity in total An. gambiae sl. collected between the ITN arms, the intervention arm (ITN arms), and the control arm (P = 0.003). An. coluzzi was identified as the predominant species in the study area, as confirmed by PCR analysis. Analysis of the blood-feeding inhibition rate revealed that 100% permethrin + PBO ITN exhibited significantly greater inhibition than 66.81% permethrin only ITN. According to the log-time probit regression analysis, permethrin exhibited a knockdown time of 256 min without synergists, while it decreased to 139 min (P = 0.001) when pre-exposed to PBO. The evidence from this trial supports the use of PBO ITNs over standard ITNs for pyrethroids to combat pyrethroid resistance and improve protection against malaria for both individuals and communities, particularly in areas with high pyrethroid resistance.
