Pheromone usage

To exclude the possibility of response toward tactile cues delivered from silk, silk has been extracted with various solvents and then retested in behavioral experiments (marked W in Table 4.1). This procedure implies pheromone usage but is not conclusive. The experimentum crucis, abehavioral test of the extract for pheromonal activity, often was not performed, particularly in older studies. A complicated issue is that solvent extraction of silk can alter its physical characteristics, as shown in... 

Thus the utility of pheromone usage may be more compatible with Integrated Pest Management practices. 

From the data available on the Internet, it may not be possible to decouple Bt cotton from other factors that may have contributed to general changes in the use of cotton pesticides following Bt cotton adoption. Changes in specific substances, however, can be linked to Bt cotton adoption, such as the decrease in the use of Gossyplure, a pheromone for the control of pink bollworm, in Arizona. Similarly, the increase in Roundup usage in... 

The first problem is simply that of relying on human knowledge in a stressful situation to obtain routes. To deal with this, the framework assumes that, at least, a few people are able to reach a safe area, i.e. shelter, out of the building, etc. and mark it on their smartphone. Then, by the unsupervised usage of the pheromone, those nodes closer to these areas will be more likely to lead people to a secure area.
