Patent number: 9290764Abstract: The present invention describes a new non-compound based approach for insect and/or arachnid control. The present inventors have identified for the first time novel targets for RNAi, which can effectively control insect and/or arachnid pest populations. Accordingly, the invention provides both nucleotide and amino acid sequences for the novel targets. Also provided are RNA constructs including double stranded RNA regions for mediating RNAi in insects, DNA constructs, expression vectors, host cells and compositions for controlling insects and/or arachnids using RNAi.

Patent number: 8906876Abstract: The present invention concerns methods for controlling insect infestation via RNAi-mediated gene silencing, whereby the intact insect cell(s) are contacted with a double-stranded RNA from outside the insect cell(s) and whereby the double-stranded RNA is taken up by the intact insect cell(s). In one particular embodiment, the methods of the invention are used to alleviate plants from insect pests. Alternatively, the methods are used for treating and/or preventing insect infestation on a substrate or a subject in need of such treatment and/or prevention. Suitable insect target genes and fragments thereof, dsRNA constructs, recombinant constructs and compositions are disclosed.Type: GrantFiled: August 23, 2012Date of Patent: December 9, 2014Assignee: Devgen NVInventors: Romaan Raemaekers, Laurent Kubler, Geert Karel Maria Plaetinck, Els Vanbleu, Thierry Andre Olivier Eddy Bogaert
