Figs. 1–7. Hypocryphalus mangiferae. – 1 in Occurrence of Nematodes Inside the Malpighian Tubules ofHypocryphalus mangiferae(Stebbing) (Coleoptera: Curculionidae: Scolytinae)

Figs. 1–7. Hypocryphalus mangiferae. – 1) SEM of the digestive tract. HG – hindgut; MG – midgut; MT – Malpighian tubule; P – pocket in the apex of Malpighian tubule. 2) SEM of the posterior of midgut showing the gastric caeca (CA). 3) Longitudinal section of digestive tract showing the single layer epithelial wall with nidi of regenerative cells (arrowheads), the digestive cells with well-developed brush border (arrow) and caeca (CA). L – midgut lumen; MT – Malpighian tubule. 4) SEM of the digestive tract showing the pocket (P) as a widened part of the Malpighian tubule (MT), which opens at the transition between midgut (MG) and hindgut (HG). 5) Stereomicroscopic image of the digestive tract showing the pocket (P) filled with nematodes. MG – midgut, MT – Malpighian tubule. 6) Longitudinal section of the pocket showing the nematodes (N). Notice that the pocket's wall is formed by a flat epithelium (arrow), apposed to the cubic epithelium of Malpighian tubules (MT). 7) Longitudinal section of the Malpighian tubule (MT) that has the widened pocket with nematodes showing a cubic epithelium at the proximal region (arrow). Notice a nematode (N) near the hindgut lumen (HL).
