The insecticidal effect of detergents on insect pests depends on concentration, and is attributed to removal of epicuticle waxes increasing susceptibility to drowning and pathogens (through indirect exposure), dislodgement, etc.
In one occasion, a change in the host exoskeleton was observed at the sBG ciliate attachment location (loss of the epicuticle at places), and in another occasion tissue infiltration was observed (Fig.
The diatomaceous earth has higher effect of adherence to the epicuticle of the insect, in comparison to the basalt dust (Subramanyam; Roesli, 2000), and the mixture of inert dusts can intensify the insecticide effect, increasing the adherence to the insects.
In electron micrographs, the cuticle is composed of two layers, an inner lamellate endocuticle and an outer epicuticle (Fig.
Morphological responses from plants to fertilizers are evident, such as changes on growing rates, acceleration or delay of maturity, size of parts of the plants, and the thickness and hardness of epicuticle, which influence the success of many pest species when attacking the host [17].
Plasma pretreatment results in physical alteration on the epicuticle layer of wool fiber surface [17], which is being a hydrophobic barrier hindering dye diffusion inside the fiber.
Cuticular lipids of the epicuticle provide insects with a barrier against body water loss (Chapman 1998).
The cuticle consists of a thin outer epicuticle containing lipids and proteins and a thick procuticle mainly consisting of chitin and proteins (Andersen et al., 1995; Samson et al., 1988).
