A method of controlling a pathogenically infected mosquito is disclosed. The method comprising administering to a larva of a mosquito an isolated nucleic acid agent comprising a nucleic acid sequence which specifically downregulates an expression of at least one mosquito pathogen resistance gene product of the mosquito, wherein downregulation of the expression of the at least one mosquito pathogen resistance gene in the larvae renders an adult stage of the mosquito lethally susceptible to the pathogen, thereby controlling the pathogenically infected mosquito.

The present disclosure relates to the production of biomass from at least one plastic polymer. More specifically, the present disclosure relates to use of a feed for production of biomass, wherein larvae of the family Pyralidae or of the family Tenebrionidae are fed on a feed comprising at least one plastic polymer, a related use of increasing pupation in a population of larva.

The invention provides methods for rearing and genetic manipulation of the genome of sap-feeding insects (e.g., whiteflies and others) to identify genetic targets for pest control, insecticides for pest control, and approaches to the genetic control of these pests.

A method of enhancing larvicide susceptibility in a mosquito larva is provided. The method comprising introducing into the mosquito larva an isolated nucleic acid agent comprising a nucleic acid sequence which specifically reduces the expression of at least one larvicide resistance gene product of the larva, thereby enhancing larvicide susceptibility in said mosquito larva.

The present invention, in some embodiments thereof, relates to methods for enhancing fitness of pathogen-infected plants, and, more particularly, but not exclusively, to methods of using RNA interference for modulation of plant-pathogen resistance response gene expression. In particular, the present invention provides compositions and methods for enhancing host plant fitness and fruit yield and quality following Candidatus Liberibacter spp infection and, specifically, Candidatus Liberibacter spp infection in citrus plants and trees, as in Huang Long Bing.

Provided is an arthropod male germline gene expression system suitable for conditional expression of an effector gene in an Arthropod male germline. The system comprises a first expression unit comprising an effector gene and a promoter therefor operably linked thereto; and a second expression unit. Said second unit comprises a coding sequence for a transcription factor and an upstream regulatory element operably linked thereto, the transcription factor being capable of acting upon the promoter in the first expression unit to drive expression of the effector gene. The upstream regulatory element includes a promoter for the transcription factor; and a 5 UTR adjacent a start site for the transcription factor coding sequence. The upstream regulatory element driving sufficient expression of the transcription factor such that the transcription factor protein in turn drives transcription of the effector gene before meiosis. Also provided are uses of the system for instance in methods of biocontrol and quality control.
