Insecticide-induced increase in the protein content of male accessory glands and its effect on the fecundity of females in the brown planthopper Nilaparvata lugens Stål (Hemiptera: Delphacidae)

Suppressing male spermatogenesis-associated protein 5-like gene expression reduces vitellogenin gene expression and fecundity in Nilaparvata lugens Stål

“…Work on individual genes and on global protein expression in insecticide- and jingGANGmycin-treated BPH34618 demonstrates the enhancing influence of agricultural chemicals on BHP reproduction and population changes. The influence of these chemicals operates through multiple systems, including carbohydrate transport19, protein biosynthesis18, developmental hormones18 and lipid biosynthesis20.…”

“…Previous studies have demonstrated that insecticide treatments enhanced BPH male accessory gland (MAG) protein content3. Compared to crossing with untreated males, females mating with insecticide-treated males led to increased fecundity, registered as numbers of eggs laid3.…”

“…Previous studies have demonstrated that insecticide treatments enhanced BPH male accessory gland (MAG) protein content3. Compared to crossing with untreated males, females mating with insecticide-treated males led to increased fecundity, registered as numbers of eggs laid3. The effects of insecticides on BPH reproduction appear to operate through a spermatogenesis-associated protein 5-like ( NlSPATA5 ) gene because it was up-regulated after triazophos (tzp)-treatment.…”

Effects of triazophos on biochemical substances of transgenic Bt rice and its nontarget pest Nilaparvata lugens Stål under elevated CO2

“…Pesticides may disrupt populations of natural enemies and affect the balance of natural enemies and their hosts. Some insecticides at sub-lethal dosages stimulate the growth and productivity of N. lugens [10,[13][14][15][16][17]. Furthermore, pesticides may affect insects indirectly, by altering the host plants' nutrition (e.g., free amino acids and sucrose), growth, development, and physiological and biochemical processes, and they can even lead to a resurgence of the target pests [18][19][20][21], although some insecticides have been found not to influence the photosynthesis rates of alfalfa [22].…”

Possible connection between imidacloprid-induced changes in rice gene transcription profiles and susceptibility to the brown plant hopper Nilaparvata lugens Stål (Hemiptera: Delphacidae)

“…The side effects of pesticides include the destruction of natural enemies [3,4], stimulation of reproduction of male and female adults [5], and pesticide-induced susceptibility of rice to BPH [6].…”
