Lepidoptera has caused huge economic losses to a variety of agricultural and forestry plants. The prevention and control measures of pests and diseases include agricultural, physical, chemical, and biological control. Microbial pesticides (including bacteria, fungi and viruses) were more and more widely used in the prevention and control of lepidopteran pests. They represent the development trend of the pesticide industry in the future and realize the sustainable control of major pests and diseases. As a novel strategy for pest control, a large number of microbial insecticides have been used in the actual production process. Although it has many advantages compared with chemical pesticides, it also has its own drawbacks. In the future, due to the search for new strategies, a variety of techniques are used in combination to form a large-scale application of microbial pesticide formulations, and continue to strengthen the application of microbial pesticides in the future lepidoptera pest control.

Plant viruses are known to indirectly manipulate insect vector behavior by altering host-plant phenotypes, yet the mechanisms by which they directly regulate vector behavior to enhance transmission remain poorly understood. Here, we reveal how the southern rice black-streaked dwarf virus (SRBSDV) reprograms the host preference of its planthopper vector, Sogatella furcifera, from infected to healthy rice plants by disrupting immune-olfactory crosstalk. We demonstrate that the SRBSDV-encoded P8 protein competitively binds to the S.

Pesticides are widely used to meet the food demands of a growing population, with various types used to control pests depending on the crops grown. Rainfall, overspray, and runoff from agricultural fields can wash these insecticides into water bodies, posing documented environmental risks. Imidacloprid is commonly used in Afrotropical regions such as South Africa, yet limited information is available on its toxicity to aquatic ecosystems within this climate region.

Rice bacterial leaf streak (BLS) caused by Xanthomonas oryzae pv. oryzicola (Xoc) significantly reduces rice yield and quality. Traditional chemical control methods often have limited efficacy and raise environmental concerns, highlighting the need for safer and more effective alternatives.

Essential oils (EOs) are a promising alternative to conventional pesticides, but some challenges like high volatility, poor water solubility, and rapid degradation limit their use in Integrated Pest Management (IPM). To overcome these limitations, this study aimed to develop garlic, eucalyptus, and clove EO-based nano-emulsions (EO-NEs) in a bait treatment format through the high-pressure microfluidization technique and investigated the biological activities against Ceratitis capitata. In addition, the adverse effects of the most promising nano-emulsion were evaluated towards a non-target parasitoid Anagaspis daci.

The rice foot rot disease caused by Dickeya oryzae is an important bacterial disease that could cause tremendous economic losses. The virulence factor modulating cluster (Vfm) quorum sensing (QS) system, a major virulence regulatory mechanism conserved in the Dickeya genus, controls the production of zeamines and various extracellular cell wall degradation enzymes in D. oryzae.
