Welcome to Lucas. Lucas was in our lab from 2021-04-19 to 2021-06-29 as a IUT student (GEII Cachan ; Paris Saclay University):
The fight against insect pests is an important issue worldwide due to crop losses, and more particularly in developing countries. Studying the life cycle of these insects may allow new control strategies to be implemented. To do this, it is necessary to measure the climatic variables and their variations in time and space. Weather stations are already present in many countries but they do not allow a measurement of the variables experienced by the insects. The objective of this internship is to design a simple device that measures the values of climatic variables and sends them to a server. It must be able to be deployed by people not specialized in electronics in the project intervention countries. The device developed is composed of an ESP32 type microcontroller connected to sensors (BME680 for temperature, relative humidity and atmospheric pressure; SI1145 for light radiation; DS18B20 for a complementary measurement of the temperature). The data is sent to the server API via POST requests using the built-in wifi card of the ESP32. The device is powered through a panel solar associated with a battery. A box made by 3D printing ensures the device protection.

Abstract: The quinoa pest Copitarsia incommoda (Walker, Lepidoptera: Noctuidae) is a cause of significant damage, and it is thus critical for Andean countries to have access to phenological models to maintain production and food safety. These models are key components in pest control strategies in the context of global warming and in the development of sustainable production integrating agroecological concepts. Phenological models are mainly based on outlining the relationship between temperature and development rate. In this study, we investigated the combined effect of protein content within the diet (artificial diet; artificial diet with −20% protein; artificial diet with +20% protein; natural quinoa diet) and temperature (12, 16.9, 19.5, 22.7, 24.6°C) as drivers of the development rate. Our study supports the literature, since temperature was found to be the main driver of the development rate. It highlights the significant role played by protein content and its interaction with temperature (significant effects of temperature, diet, and diet:temperature on development time using GLMs for all foraging life stages). We discuss the implications of such drivers of the development rate for implementing and applying phenological models that may benefit from including factors other than temperature. While performance curves such as development rate curves obtained from laboratory experiments are still a useful basis for phenological development, we also discuss the need to take into account the heterogeneity of the insect response to environmental factors. This is critical if pest control practices are to be deployed at the optimal time.

1. Insect crop pests are responsible for many crop losses. The fight against these insects plays a central role in the food security for the populations, it is therefore important to build models to predict the phenology of these insects in order to intervene at the right time.
2. Some information is available through weather stations, but they are not sufficient: a finer resolution is necessary for studying local conditions. In particular, the plant cover greatly influences the values of temperature, relative humidity, and the brightness perceived by insects.
3. The project aims to develop local units, based on a microcontroller, to measure various parameters of the conditions experimented by insects. These local units communicate with a server for further data analysis.
4. The components necessary for the realization of the project represent less than 20€, also offering the transmission of data to the server. This lower cost, in addition to increased flexibility, allows measuring conditions associated with a micro-environment, leaving a much finer resolution for studying insects.
5. In view of the wide availability of these components today, and given the ease of assembly of the card, requiring no qualification particularly, these terrain sensors will see an increase importance in the coming years.
6. In parallel, a server allowing the centralization of data is proposed, in order to allow a study on a larger scale and on different continents of insect pests.
Welcome to Aghiles. Aghiles was in our lab from 2020-03-13 to 2020-08-31 as a Master2 student (E3A Mobile Automatic Systems ; Evry and Paris Saclay University):
As part of the Master 2 mention Automatic Mobile Systems, at the University of Evry Val d’Essonne, Paris-Saclay, I had the opportunity to do a Six-month internship in the EGCE research laboratory at Gif-Sur-Yvette. The objective of my internship is to create a network of sensors connected to the agricultural scale. Going through the choice of the most suitable sensors for the project and the design of a wind speed sensor closest to a professional anemometer.
