The fall armyworm(Spodoptera frugiperda) is an invasive species and a destructive pest of maize, which significantly impacts native species and communities via complex mechanisms like competition for resources. However, the interaction between S. frugiperda and local pests remains unclear. In this study, we determined that Oriental armyworm(Mythimna separata) females with different mating status displayed different approach–avoidance behaviors towards maize which was infested by S. frugiperda larvae. The virgin M. separata females were repelled, while the mated females were attracted by the S. frugiperda-infested maize. To further understand the olfactory mechanism of this phenomenon, seven volatiles induced by S. frugiperda in maize were characterized by gas chromatography and mass spectrometry(GC-MS), including trans-2-hexenal, linalool, trans-β-farnesene, cis-3-hexenyl acetate, β-caryophyllene, trans-α-bergamotene, and isopentyl acetate. Additionally, electrophysiological and behavioral assays of the seven compounds were performed using both virgin and mated females of M. separata. We determined that virgin and mated females displayed different responses to the herbivore-induced plant volatile(HIPV).Trans-β-farnesene was the core compound for repelling virgin females, and trans-2-hexenal was the key attractant for oviposition in mated female M. separata individuals. These findings help our comprehension of the relationships between maize pests and offer new possibilities for controlling them by olfactory-based strategies.

The Pomacea canaliculata, also known as apple snail, is an invasive species in China, posing a serious threat to agricultural production and public health. To prevent its rampant infestation, we developed a highly efficient snail-killing lead compound, 1-(4-chlorophenyl)-3-(pyridin-3-yl)urea (PBQ). However, the killing mechanism of PBQ remains unclear. To elucidate this, two novel compounds, B-PBQ and J-PBQ, were developed through structural modification of PBQ and were used, through both protein pull-down assay and confocal laser scanning microscopy imaging, to identify and confirm that phosphofructokinase(PFK) in the apple snail is the primary target protein of PBQ. Further studies revealed that PBQ successfully inhibits the activity,content, and expression of PFK in apple snail, disrupting the glycolysis pathway and leading to abnormal energy *** disruptions impair the snail’s tolerance to low oxygen, resulting in its efficient eradication. These findings offer a promising direction for developing next-generation PFK-targeted snail-killing pesticides. Furthermore, the strategy of combining pull-down assays with optical imaging used in this work provides a novel approach for the exploration of mechanisms of other pesticide candidates.

White light illumination is essential in daily life, however, the substantial amount of blue light it contains can damage human eyes. Therefore, it is important to block this high-energy blue light to protect visual health. In this study, yellow-emitting carbon dots(CDs) with a quantum yield exceeding 94% were synthesized using citric acid and urea. These CDs effectively absorb blue light. By incorporating them into polystyrene, multiple films termed CDs-based blue light blocking films(CBFs) were developed, each offering different levels of blue light absorption. These CBFs exhibited excellent transparency and efficient blue light filtering capabilities. This study highlights the potential of high quantum yield CDs, which specifically absorb blue light, as foundational materials for developing light-blocking solutions against highenergy short-wavelength light.
