Insecticidal (dihalopropenyl) phenylalkyl substituted dihydrobenzofuran and dihydrobenzopyran derivatives of Formula I are disclosed. These compounds provide unexpected insecticidal activity across a spectrum of insect pests combined with desirable physical properties including improved photostability. Wherein x and y are integers independently selected from 0 or 1; and B is a bridging group *-(CR16R17)q-(CR18R19)r-(CR20R21)s-Lt-(CR22R23)u-(CR24R25)v- (CR26R27)w-, where the asterisk denotes attachment at A; and q, r, s, u, v and w are integers independently selected from 0, 1 and 2; and t is an integer selected from 0 and 1. A, D, B, G, M, R through R11, and R16 through R27, inclusively, are fully described herein. In addition, compositions comprising an insecticidally effective amount of at least one compound of formula I and methods of controlling insects by applying said compositions to a locus where insects are present or are expected to be present are also disclosed.

L'invention concerne des dérivés insecticides de dihydrobenzofurane et de dihydrobenzopyrane à substitution (dihalopropényl)phénylalkyle représentés par la formule générale (I). Ces composés présentent une activité insecticide inattendue dans le spectre des insectes nuisibles, combinée à des propriétés physiques recherchées, y compris une meilleure stabilité à la lumière. Dans la formule générale (I), x et y sont des entiers qui valent 0 ou 1 ; et B désigne un groupe en pont *-(CR?16¿R?17¿)¿q?-(CR?18¿R?19¿)¿r?-(CR?20¿R?21¿)¿s?-L¿t?-(CR?22¿R?23¿)¿u?-(CR?24¿R?25¿)¿v?-(CR?26¿R?27¿)¿w?-, l'astérisque indiquant la liaison à A ; et q, r, s, u, v et w sont des entiers qui valent 0, 1 ou 2 ; et t est un entier qui vaut 0 ou 1. A, D, B, G, M, R-R?11¿ et R?16¿-R?27¿, inclus, sont tous décrits dans la partie descriptive de la présente demande. L'invention concerne également des compositions comprenant une dose efficace d'au moins un composé représenté par le formule générale (I) et des procédés permettant de lutter contre les insectes, consistant à appliquer ces compositions à un emplacement où ces insectes sont présents ou attendus.
