“…in Forbes 1954), in Camponotus pennsylvanicus (Forbes 1954), in Neivamvrmex harrisi (Forbes & Do-VanQuy 1965) and we found it in representative species of all major subfamilies of ants. The size of the paired penis gland clusters (which are also called aedeagal gland, Forbes 1954) varies greatly among different species. In some it is a major gland (Fig.…”

“…These glands are thought to play several roles (Forbes and Macfarlane 1961, Ayre 1963, Delage 1968, Thompson et al 1981, Vander Meer et al 1982, Attygalle et al 1985, Soroker et al 1994, Kaib et al 2000, and according to some authors, they are a diverticulum of the digestive tract (Caetano et al 2002). Peregrine et al (1974), Zylberberg et al (1974), DelageDarchen (1976), Vinson et al (1980), andVander Meer et al (1982) think these glands might play a role as cephalic or gastric cecum.…”

The current study compared the toxicity of different concentrations of boric acid in adult workers of Atta sexdens rubropilosa Forel (Hymenoptera: Formicidae), with toxicological bioassays, and examining the dose-dependent and time-dependent histopathological changes, of the midgut, Malpighian tubules, and postpharyngeal glands. Our results revealed the importance of conducting toxicological bioassays combined with morphological analyses of the organs of ants chronically exposed to insecticides used in commercial ant baits. In vitro bioassays showed that boric acid significantly decreases the survivorship of workers regardless of concentration, whereas the morphological data suggested progressive dose-dependent and time-dependent changes in the organs examined, which were evident in the midgut. The midgut is the first organ to be affected, followed by the postpharyngeal gland and Malpighian tubules. This sequence is in agreement with the absorption pathway of this chemical compound in the midgut, its transference to the hemolymph, possibly reaching the postpharyngeal glands, and excretion by the Malpighian tubules. These progressive changes might be due to the cumulative and delayed effect of boric acid. Our findings provide important information for the understanding of the action of boric acid in ant baits in direct and indirect target organs.

“…The latter are transported via hemolymphatic lipophorin to the tissues for utilization (Canavoso et al, 2001). Delage-Darchen (1976), Forbes and Mcfarlane (1961) suggested that PPGs may be responsible for the digestion of ingested fats, as digestive enzymes -the lipases -are present in the lumen (Peregrine et al, 1973;Vinson et al, 1980). Corroborating Decio (2013), Lipase 3 has been detected by two-dimensional gel electrophoresis in the PPGs of A. sexdens rubropilosa.…”

“…Peregrine et al (1972Peregrine et al ( , 1973, Mudd (1974), andDelage-Darchen (1976) were the first to describe the content of lipids and the anatomy of PPGs. Delage-Darchen (1976) and Forbes and Mcfarlane (1961) suggested that PPGs are responsible for the digestion of ingested fats, as they contain digestive enzymes in the lumen such as lipases (Peregrine et al, 1973;Vinson et al, 1980). However, the influence of lipid droplets stored in PPGs on morphological alterations has not been clearly documented.…”
