Artificial neural networks for monitoring network optimisation—a practical example using a national insect survey (2020)
Journal Article
Bourhis, Y., Bell, J., Bosch, F., V. D., & Milne, A. (2021). Artificial neural networks for monitoring network optimisation—a practical example using a national insect survey. Environmental Modelling and Software, 135, Article 104925. https://doi.org/10.1016/j.envsoft.2020.104925

Monitoring networks are improved by additional sensors. Optimal configurations of sensors give better representations of the process of interest, maximising its exploration while minimising the need for costly infrastructure. By modelling the monitor...

Money spider dietary choice in pre‐ and post‐harvest cereal crops using metabarcoding (2020)
Journal Article
Cuff, J. P., Drake, L. E., Tercel, M. P., Stockdale, J. E., Orozco-terWengel, P., Bell, J. R., …Symondson, W. O. (2021). Money spider dietary choice in pre‐ and post‐harvest cereal crops using metabarcoding. Ecological Entomology, 46(2), 249-261. https://doi.org/10.1111/een.12957

Money spiders (Linyphiidae) are an important component of conservation biological control in cereal crops, but they rely on alternative prey when pests are not abundant, such as between cropping cycles. To optimally benefit from these generalist pred... Read More about Money spider dietary choice in pre‐ and post‐harvest cereal crops using metabarcoding.

Smart Armyworm Surveillance: Project Technical Report (2020)
Report
Pearson, A., Bell, J., Subramanian, S., & Ouma, K. (2020). Smart Armyworm Surveillance: Project Technical Report. Bill and Melinda Gates Foundation; Biotechnology and Biological Sciences Research Council

This project was designed to test three different technologies for monitoring the fall armyworm, a highly migratory moth pest of maize in Kenya. This insect is invasive and is estimated to have caused between US$200 and US$600 million dollars’ worth... Read More about Smart Armyworm Surveillance: Project Technical Report.

UK aphid migration percentiles, covariates and model outputs from the Rothamsted Insect Survey's 12.2 m suction-trap network: 1965 to 2018 (2020)

Although we have known anecdotally that insects have been declining in Great Britain for more than 100 years, insect declines have only been statistically estimated over the last 20 years. Estimation of the rate of those declines is still hotly debat... Read More about Are insects declining and at what rate?
