Genetic pest management review

Image: Fig 1D from Harvey-Samuel et al. (2017) Biol Invasions depicting the self-limiting aromatase sex ratio distortion strategy for genetic pest management (Fig details below). A nice review of genetic pest management (GPM) strategies for invasive species, by Tim Harvey-Samuel, Thomas Ant & Luke Alphey (of Oxitec fame), is presented in the recent issue of Biological Invasions. I spent a lot of time reviewing the GPM literature back in 2012 and 2013, but I haven’t kept up to date on many…

Pest control ~ Landscape complexity

Image: Fig 1 from Rusch et al. (2016) Agric Ecosyst Environ. It’s well demonstrated that increased habitat complexity tends to increase arthropod biodiversity and, importantly, the abundance of natural enemies. Therefore, it is thought that increasing complexity in agricultural landscapes should increase the level of pest control too. But is this true? Does increased landscape complexity actually result in fewer pests? There have been a few great studies that have looked at this question (e.g. Gardiner…
