Our field bioassay cages are designed for robust and reliable insect research under natural environmental conditions. Constructed from various grades of nylon mesh, these cages are tailored to suit both large and small insect species. For studies involving small insects, we offer 40-mesh monofilament netting—an economical option that effectively prevents entry or escape of even the tiniest insects. While durable, its thicker thread design may slightly limit visibility. To address this, we also provide cages made with exceptionally fine nylon netting featuring thinner individual threads. These premium nets offer superior visibility without compromising on containment, making them ideal for both professional-grade research and precision entomological studies. Suitable for field trials, host plant interaction assessments, and insecticide efficacy testing, our cages ensure flexibility, containment integrity, and observational clarity.
