Oak processionary experiment with bird houses for the great tit has been carried out since 2016. It has been observed that the great tit likes to eat the young, not yet hairy caterpillars in the month of April. In serious cases of contamination, the use of relatively mild chemical pest killers has been allowed by local authorities. Because chemicals may be harmful to other insects, an alternative is the use of vacuuming equipment to remove the caterpillars, followed by incinerating the caught specimens. Oak processionary The oak processionary "(Thaumetopoea processionea)" is a moth whose caterpillars can be found in oak forests. They
Hazard substitution data, making alternatives assessments difficult. Another type of regrettable substitution involves shifting the burden of a hazard to another party. One example is that the potent neurotoxin acrylamide can be replaced with the safer "N"-vinyl formamide, but the synthesis of the latter requires use of the highly toxic hydrogen cyanide, increasing the hazards to workers in the manufacturing firm. In performing an alternatives assessment, including the effects over the entire product lifecycle as part of a life-cycle assessment can mitigate this. Hazard substitution Hazard substitution is a hazard control strategy in which a material or process is replaced with another
