“…A detailed study of the chemical composition of microvilli (microvillar membranes plus contaminating cytoskeleton) from Bombyx mori midgut cells (Leonardi et al 2001) confi rms the previous data. Thus, protein-lipid ratio is smaller (1.85) in anterior plus middle in comparison to posterior midgut (2.30).…”

Plasma membranes from insect midgut cells are separated into apical and basolateral domains. The apical domain is usually modifi ed into microvilli with a molecular structure similar to other animals. Nevertheless, the microvillar structure should differ in some insects to permit the traffi c inside them of secretory vesicles that may budd laterally or pinch-off from the tips of microvilli. Other microvillar modifi cations are associated with proton-pumping or with the interplay with an ensheathing lipid membrane (the perimicrovilllar membrane) observed in the midgut cells of hemipterans (aphids and bugs). The perimicrovillar membranes are thought to be involved in amino acid absorption from diluted diets. The microvillar and perimicrovillar membranes have densities (and protein content) that depend on the insect taxon. The role played by the microvillar and perimicrovillar proteins in insect midgut physiology is reviewed here trying to provide a coherent picture of data and highlighting further research areas.

Insect growth regulators generally have a selective effect on the target insects and have practically no apparent side effect on non-target organisms especially vertebrates. Hence, insect growth regulators could be a suitable choice to control pests in stored products. Ten-day-old larvae of Indian meal moth Plodia interpunctella (Hübner) were expressed to the juvenile hormone analogue pyriproxyfen in order to have an effect on growth, metamorphosis, reproduction, lipid and protein contents of ovaries. The larvae were treated by 0.02, 0.04, 0.08, 0.16, and 0.3 ppm of JHA in an artificial diet where controls received acetone alone. The results indicated significant differences in duration of growth, mean longevity of hatched adults, percentage of emerged normal adults, abnormal pupae, hatched larvae and mean oviposition ratein addition to the lipid and protein of ovaries compared to the controls. An inhibition concentration of fifty (IF 50 ) for prevention of emerging adults was recorded 0.134 ppm. Pyriproxyfen caused significant defects in the legs and wings of some adults and sever morphological changes in the ovaries of emerged adults. The results showed that pyriproxyfen may be applied as an insecticide to decrease the damage caused by Indian meal moth on stored products. Pyriproxyfen can be used with low side effects to humans.

“…Non-spinning syndrome threatens not only the production of breeding cocoons and eggs, but also affects commercial cocoon production in Turkey and other countries such as Iran, China and Brazil (Monconduit & Mauchamp, 1998;Leonardi et al, 2001;Sun et al, 2012;Sahan et al, 2019). Additionally, both native and foreign sourced silkworm lines are under great risk because of this syndrome.…”

“…Sericulture has experienced serious problems with non-spinning syndrome in B. mori in sericulture practicing countries affecting silkworm rearing and silk production. Although cocoon and raw silk production have continued to be historically, traditionally and culturally practiced in Turkey (Sahan, 2011), recently, both cocoon and silkworm egg production have faced this problem in different regions of Turkey like other countries (Monconduit & Mauchamp 1998;Leonardi et al, 2001;Sun et al, 2012;Sahan et al, 2019). Therefore, it is important to determine the cause of and find solutions to this syndrome in silkworms.…”
