There is no established method for recovering helminth eggs in soil has yet to be established. Here, we introduce a novel method for their recovery based on a centrifugal flotation approach using a sucrose solution with a specific gravity of 1.20, with a coverslip being placed on the sucrose-filled centrifuge tube during centrifugation. The recovery of zoonotic Toxocara eggs from soil was more effective when this method was compared with the traditional flotation method. This method detects not only zoonotic Toxocara eggs, but Ascaris lumbricoides, Trichuris trichiura, and other human parasite eggs also, indicating that it can be used for epidemiological studies both in developed and developing countries.

Soilborne diseases are persistent problems in soybean production. Long-term crop rotation can contribute to soilborne disease management. However, the response of soilborne pathogens to crop rotation is inconsistent, and rotation efficacy is highly variable.

Ambient hypoxia can pose a major threat to the survival of metazoan organisms, especially insect embryos. Hemocyanin exhibits dominant expression in insect embryos, but its specific roles in hypoxia adaptation remain unexplored. Soil-dwelling locust eggs may frequently experience hypoxia during development.

Background: Diagnosis of soil-transmitted helminthiasis and schistosomiasis for surveillance relies on microscopic detection of ova in Kato-Katz (KK) prepared slides. Artificial intelligence (AI)-based platforms for parasitic eggs may be developed using a robust image set with defined labels by reference microscopists. This study aimed to determine interobserver variability among reference microscopists in identifying parasite ova.

Bagrada bug, (Burmeister) (Hemiptera: Pentatomidae), is an invasive pest of cole crops in the United States. Because it also feeds on widespread weeds and persists in natural habitats surrounding crop fields, conventional control strategies are often ineffective at providing long-term control. One egg parasitoid, Talamas (Hymenoptera: Scelionidae), is a promising biological control candidate because of its ability to parasitise buried eggs.
