We describe a new pest of guava ( L.), Stonis & Vargas, , that was recently discovered in western Colombia. van Nieukerken is a small, Neotropical genus of pygmy moths (Nepticulidae). We re-examine and document the complex morphology of the male genitalia of the generic type species, (Puplesis & Robinson). We discuss the diagnostics and composition of the genus and provide a simple pictorial differentiation scheme for all currently known representatives of the genus. The new species is illustrated with photographs of the adults, some of the immature stages, male and female genitalia, and leaf mines. A link to the COI barcodes of is provided and the relationship of to other genera is discussed.

Meloidogyne enterolobii, a guava root-knot nematode, is a highly virulent pest in tropical and subtropical regions causing galls or knots in roots of diverse plant species posing a serious threat to agriculture. Managing this nematode is challenging due to limitations in conventional identification based on isolation and microscopic classification requiring expertise and time. A colorimetric and fluorescent LAMP assay using simplified extraction method targeting rDNA-ITS region was developed to detect M.

Despite seemingly inexorable imminent risks of food insecurity that hang over the world, especially in developing countries like Pakistan where traditional agricultural methods are being followed, there still are opportunities created by technology that can help us steer clear of food crisis threats in upcoming years. At present, the agricultural sector worldwide is rapidly pacing towards technology-driven Precision Agriculture (PA) approaches for enhancing crop protection and boosting productivity. Literature highlights the limitations of traditional approaches such as chances of human error in recognizing and counting pests, and require trained labor.

This study explores an eco-friendly approach to mitigate risks associated with organophosphorus insecticides, particularly Chlorpyrifos, by synthesizing silver nanoparticles (AgNPs) using Psidium guajava leaf extract and preparing a nanocomposite (AgNPs/S18) with Chlorpyrifos pesticide. The green-synthesized AgNPs and AgNPs/S18 nanocomposite were characterized using various analytical techniques, confirming the successful synthesis of AgNPs with an average size of 37 nm and forming a stable nanocomposite. Antibacterial assays demonstrated significant activity against Staphylococcus aureus, with AgNPs showing an 87.

Key Laboratory of Entomology and Pest Control Engineering, College of Plant Protection, Southwest University, Chongqing 400715, China.

Article Synopsis
  • Kuwayama is a major pest in the citrus industry responsible for spreading Citrus Huanglongbing disease and has developed resistance to chemical insecticides, highlighting the need for environmentally friendly pest management solutions.
  • The study evaluated the repellent and insecticidal effectiveness of essential oils from four plant species, finding that eucalyptol had the strongest repellent activity and that all tested essential oils displayed insecticidal properties with varying degrees of efficacy.
  • Chemical analysis of the essential oils revealed high concentrations of terpenoids and other compounds, suggesting their potential use as biological alternatives to traditional pesticides.
