The paralysis behavior of some ponerine ants when foraging may be important for food storage and colony development. However, how workers invest in paralysis under different prey circumstances is often overlooked. Here, we report the prey-foraging behavior and paralysis behavior of Harpegnathos venator under different food supply conditions. Solitary hunting was the main foraging mode of H. venator, with occasional simple collective hunting. Nymphal cockroaches with high activity were the most attractive to H. venator. In the experiment, we found that the stings of H. venator completely paralyzed the cockroaches. The stinging time was significantly longer at a higher prey activity level and for larger cockroaches. In addition, there was no significant difference in the stinging time of H. venator for different prey densities. The results showed that the longer similar cockroaches were stung, the longer it took for them to revive and move. These results are helpful for further understanding the behavioral mechanism underlying the food storage of live prey by predatory insects.

Rhynchomicopteron necaphidiforme sp. n. is described from West Malaysia, where it is associated with a Ponerine ant. The female matures a single egg at atime. Silvestri's (1947) specimen from lndo-China attributed to R. caecutietts Schmitz is recognised as a new species and named R. silvestrii sp. n. A key to the eleven known species of Rhyrtchonticropteron is provided.

How do natural disasters affect rebel group recruitment? Some influential research to date suggests that natural disasters – by lowering the opportunity cost of joining an armed movement – are likely to facilitate rebel group recruitment. In contrast, this study argues that natural disasters can negatively affect rebel organization and their recruitment efforts. It posits that natural disasters may weaken rebel groups in two main interrelated ways: (1) by leading to acute scarcity for rebel combatants and supporters, weakening the rebel group’s organizational structure and supply lines, and (2) by increasing government and international presence in areas where the insurgents operate. Empirically, this article explores these suggested mechanisms in two cases of natural disasters in the Philippines (typhoons Bopha in 2012 and Haiyan in 2013), which affected regions partially controlled by the communist rebel group, the New People’s Army (NPA). Based on data from extensive fieldwork, there is no evidence suggesting a boom in rebel recruitment in the wake of the typhoons. Rather, the NPA was temporarily weakened following the tropical storms, significantly impacting the civil war dynamics in the Philippines.
