Increased expression of Chemosensory Protein gene in field populations of insects

What is it about?

It is about the functional role of an insect protein gene family, namely Chemosensory Proteins (CSPs). This is the first report about CSPs in aleyrods. We cloned CSP in the sweet potato whitefly Bemisia tabaci. We then compared CSP gene expression across biotypes, sexes and laboratory/field populations. We found that CSP was particularly highly expressed in females of a Q biotype field population.

Why is it important?

It is important because this is the first report about CSPs in aleyrods and whiteflies. It is also very important because this is the first report dealing with CSPs in insecticide resistance. CSPs were long known and heavily described in the insect chemosensory system. Our finding rather orientates CSP research towards functions in relation with xenobiotics degradation and adaptation to specific chemical environment.

Alike most common insect pests, aleyrods and whiteflies are known to develop high insecticide resistance capacity, which makes their control rather difficult. to implement. The detail function of CSPs in insecticide resistance has been brought up by Liu et al. (PLOS ONE, 2016). The discovery that CSPs play a key role at different levels of the immunity response might open new way to counteract insect defense systems, thereby allowing new efficient control strategies more compatible with environmental protection.
