The phloem is a well-known target of sucking and piercing insects that utilize the transported
fluid as their major nutrient source. In addition to small molecules like sugars and amino …

The sap sucking insects (Hemiptera), which include aphids, whiteflies, plant bugs and stink
bugs, have emerged as major agricultural pests. The Hemiptera cause direct damage by …

Transmission electron micrographs of the pea aphid midgut revealed that its anterior region
has cells with an apical complex network of lamellae (apical lamellae) instead of the usual …

Publisher Summary This chapter focuses on geminivirus insect–pathogen hypothesis. Most
of viruses infecting plants rely on insects to move from one host to another. Some remain …

Proteinase inhibitors which act on the digestive enzymes of insect herbivores are a basic
mechanism of plant defence. Attempts to exploit this defence mechanism in plant genetic …

The spatial organization of digestion, which corresponds to the steps by which the ingested
food is hydrolyzed in the different regions of the gut, was described in insects from the major …

A microscopic analysis of the morphology and ultrastructure of the digestive, salivary, and
reproductive systems of adult Bemisia tabaci (Gennadius)(Hemiptera: Aleyrodidae) B type …

Using serial block-face scanning electron microscopy, we report on the internal 3D
structures of the brown planthopper, Nilaparvata lugens (Hemiptera: Delphacidae) at …

We have characterized proteinase activities in gut extracts from the cotton‐melon aphid
(Aphis gossypii Glover), an insect feeding strictly on protein‐poor phloem. The major, if not …
