the capsule type i 30 may have a first capsule type i portion 40 and a second capsule type i portion 50 fig2 illustrates a member 10 as a capsule type i 30 in its closed position from the closed position or deployable state 180 as illustrated at fig2 4 a 4 b and 11 the member 10 can be propelled toward a tree then due to inertia the member 10 will separate from at least one of either capsule type i 30 capsule type ii 60 or capsule type iii 110 to an attachment state 200 as illustrated in fig7 from which the extension 120 may wrap around a branch holding the releaser 20 in the air to release the desired pheromones then when member 10 contacts a tree branch the member 10 may wrap around the branch where it remains to deploy a pheromone into the air to disrupt the mating process of invading insects fig3 illustrates another type of member 10 this member 10 may be referred to as the capsule type ii 60 the capsule type ii 60 may have a first capsule ii portion 70 and a second capsule ii portion 80 the first capsule ii portion 70 may have a first capsule ii hollow interior 90 the second capsule ii portion 80 may have a second capsule ii hollow interior 100 the capsule type ii 60 can be closed as illustrated in fig4 a and 4 b fig4 a illustrates the capsule type ii 60 with the releaser 20 stowed inside the capsule type ii displaced at least one of the first capsule ii hollow interior 90 and the second capsule ii hollow interior 100 the member.
