The use of predatory Hemiptera (Pentatomidae: Asopinae) in agroecosystems has
increased considerably in the last decades. All Asopinae representatives are obligate …

Juvenile hormone analogs (JHA) are known to interfere with growth and biosynthesis of
insects with potential for insecticide action. However, there has been comparatively few data …

The peritrophic matrix is a chitin-protein structure that envelops the food bolus in the midgut
of the majority of insects, but is absent in some groups which have, instead, an unusual extra …

The effects of ingested neem oil, a botanical insecticide obtained from the seeds of the neem
tree, Azadirachta indica, on the midgut cells of predatory larvae Ceraeochrysa claveri were …

Pre-oral digestion is described as the liquefaction of the solid tissues of the prey by
secretions of the predator. It is uncertain if pre-oral digestion means pre-oral dispersion of …

Larvae are the most important feeding and developmental stage in the life cycle of insects.
Correspondingly, the larval midguts, as the primary digestive organs, undergo diverse …

Larvae of the lacewing Ceraeochrysa claveri were fed on eggs of Diatraeasaccharalis
treated with neem oil at concentrations of 0.5%, 1% and 2% throughout the larval period …

The neonicotinoid thiamethoxam is widely used in different agricultural crops, and it has a
spectrum of action against insects, affecting both pests and pollinators, such as bees. In this …

This work studied the ultrastructure of the midgut cells of Cimex hemipterus Fabricius
(Hemiptera: Cimicidae). The midgut of adult insects was analyzed on different days after a …

Cell death, proliferation, and differentiation in some developmental stages of insects have
been studied in the midgut of ametabolous, which undergo only continuous growth, and …
