  Promoters are described for vanadium-based catalysts used in the (co)polymerization of olefins and, in particular, in the production of ethylene/propylene (EPR) or ethylene/propylene/diene (EPDM) elastomeric copolymers. The promoters of the present invention belong to the group of compounds having general formula I: wherein: "X" represents a (-CO-) carbonyl or (-SO2-) sulfonyl group; "n" is 0 or 1; R' is an alkyl or alkylaryl group having from 1 to 20 carbon atoms;         R" = R', H.

  本发明描述了用于烯烃（共）聚合，特别是用于生产乙烯/丙烯（EPR）或乙烯/丙烯/二烯（EPDM）弹性共聚物的钒基催化剂的促进剂。本发明的促进剂属于具有通式 I 的化合物组： 其中 "X "代表(-CO-)羰基或(-SO2-)磺酰基； "n "是 0 或 1； R'是具有 1 至 20 个碳原子的烷基或烷基芳基； R" = R'，H。

  The invention comprises methods for decreasing colonization by a bacterium of a gut of a stink bug, the method comprising providing a composition comprising vanillin or an analog thereof; and delivering said composition to an egg from which the stink bug will hatch, whereby colonization by the bacterium within the gut of the stink bug hatched from the egg treated with the composition is decreased relative to a stink bug hatched from an untreated egg. In some embodiments, the decrease in colonization by the bacterium decreases the fitness of the stink bug, e.g., decreases reproductive ability, survival, rate of development, number of eggs, number of hatched eggs, adult emergence rate, body length, body width, body mass, or cuticle thickness. In some embodiments of the methods herein, the bacterial colonization-disrupting agent is an inhibitor of bacterial metabolism. In some embodiments, the bacterial colonization-disrupting agent is a polyhydroxyalkanoate (PHA) synthesis inhibitor.
