The Scots pine cone weevil, Pissodes validirostris Gyll. (Coleoptera: Curculionidae) widely distributed from Europe, across to North-Eastern China, consumes the cones of Mediterranean pines, as well those of the sylvestris section. The use of multiple host pine species with limited and patchy distributions, combined with low dispersal rates, likely contributed to significant genetic and morphological variation among P. validir...

Many native South African grass species have become invasive elsewhere in the world. The application of biological control to invasive grasses has been approached with trepidation in the past, primarily due to concerns of a perceived lack of host specific herbivores. This has changed in recent times, and grasses are now considered suitable candidates. The Tetramesa Walker genus (Hymenoptera: Eurytomidae) has been found to cont...

The third objective of the Convention on Biological Diversity, the fair and equitable sharing of benefits arising out of the use of genetic resources was further developed when the Nagoya Protocol on Access and Benefit Sharing came into effect in 2014. Interpretation of how this agreement is being implemented is wide-ranging and there are implications for biological control. A survey of biological control workers indicated tha...
