Cassava is one of the most important tuber crops that is used for food, starch and bio-energy. However, cassava is susceptible to a number of diseases, especially cassava bacterial blight (CBB). Nitric oxide (NO) and hydrogen peroxide (H2O2) regulate plant growth and development, as well as stress responses.

(Coquillett) is a highly damaging agricultural pest in many tropical and subtropical countries around the world and high temperatures usually affect its survival. To clarify the effect of short-term high temperatures on the survival and lifespan of , newly emerged adults of three consecutive generations (F, F, and F) were exposed to 25 °C, 33 °C, 37 °C, 41 °C, or 45 °C treatments for 1 h. The effect of these temperatures on survival and lifespan was evaluated using biological indicators such as lifespan and pupation rate.

Article Synopsis
  • Climate change is altering the distribution of pests and their natural enemies, making it crucial to predict these changes for effective pest management.
  • The research analyzes the spread trends of key vegetable pests and their natural predator, the hoverfly, using historical data and the MaxEnt model under different climate scenarios (1970-2000 and 2041-2060).
  • Results indicate that certain future climate conditions (RCP 2.6 and RCP 4.5) favor pest spread, while others (RCP 8.5) do not, highlighting the importance of temperature and precipitation for the survival of both pests and predators.

The harm of agricultural pests presents a remarkable effect on the quality and safety of edible farm products and the monitoring and identification of agricultural pests based on the Internet of Things (IoT) produce a large amount of data to be transmitted. To achieve efficient and real-time transmission of the sensors' data for pest monitoring, this paper selects 235 geographic coordinates of agricultural pest monitoring points and uses genetic algorithm (GA), particle swarm optimization (PSO), and simulated annealing (SA) to optimize the data transmission paths of sensors. The three intelligent algorithms are simulated by MATLAB software.

Climate change has increased the frequency of extreme heat events. (Coquillett) is an important tropical pest that typically changes its reproductive strategies in response to extremely high temperatures. Newly emerged adults of three consecutive generations (F, F, and F) of (Coquillett) were exposed to 25°C, 33°C, 37°C, 41°C, and 45°C treatments for 1 h to clarify the effects of short-term high temperatures on its reproduction.
