The unprecedented target-specificity of double-stranded RNA (dsRNA), due to its sequence-specific mode action, puts dsRNA at the forefront biosafe insecticide technology. Since 2007, sensitive target genes have been identified in numerous crop pest insects, with an end goal applying interference (RNAi) management. Key RNAi targets include involved (1) feeding and digestion, (2) production dsRNa...

BACKGROUND The brown planthopper (BPH), Nilaparvata lugens Stål, is a major rice pest in many parts of Asia. Neonicotinoids such as imidacloprid and dinotefuran are widely used for control of this pest, and resistance to these insecticides has developed in recent years. This pest has also been widely exposed to triazophos and fenvalerate, although these insecticides are not used for the control...

the german cockroach, blattella germanica, is one of the most common pest species, and is acarrier of many pathogen and allergen factors in humans. thus, regarding public health, the control of thisinsect is quite important. dietary use of hormone analogues, especially juvenoids which disrupt reproductiveorgan development, is a relatively new method to control cockroaches. in this study, the ef...

1. Understanding predator–prey interactions of the arthropod community in any given ecosystem is essential in pinpointing the biological control services provided by natural enemies. 2. Hence, four prey-specific polymerase chain reaction (PCR) assays were developed to analyse the gut contents of the cotton predator community. The four targeted prey included a herbivore/pest, omnivore/pest, omni...
