Dorsal Abdominal Glands

The three dorsal abdominal glands in larvae of Apateticus bracteatus (Pentatomidae) secrete a mixture of compounds. Major volatile constituents of the secretion are identified, herein, as tridecane and 2-octenal. There are also trace amounts of 2-hexenal and two other unidentified compounds.Each of the glands has paired orifices that are located between tergites 3/4, 4/5, and 5/6, but only the most anterior gland is paired. In anterior glands of midinstar larvae, glandular cells associated with ducts, and interstitial glandular cells are distributed along the ventral walls of the reservoirs. In posterior glands, columnar glandular cells are located in the anterior dorsal wall of the reservoirs; secretory cells associated with ducts, and nonglandular interstitial cells are distributed throughout the ventral and posterior walls of the reservoirs. The interstitial glandular cells of the anterior gland and the columnar glandular cells of the middle and posterior glands contain cytoplasmic organelles characteristic of lipid-producing cells. In all glands the secretory cells associated with ducts secrete lipids. Evidence indicating the importance of Golgi and ER in secretion synthesis is presented. The reservoirs and ducts have a thin cuticular lining.The bearing of the results on present ideas of gland function in Heteroptera is discussed.

Volatile components of seven Frullania species (Frullaniaceae) from New Caledonia, including five endemic species ( F. bella, F. scalaris, F. mammillosa, F. cornuta and F. falsicornuta), were analyzed by GC-MS in order to index these plants to known chemotypes. Constituents detected in these Frullania species were mainly sesquiterpenes, as well as the bibenzyl dihydrognetin, and the flavonoid naringinin-5,7,4'-trimethyl ether. These compositions allowed an indexation of Frullania species from New Caledonia to cyclocolorenone, sesquiterpene lactone and bibenzyl chemotypes. In addition, qualitative intraspecies variations of chemical composition were very important and made indexation to known chemotypes very tricky. Moreover, two of the endemic liverworts did not possess any biomarker that linked to a known chemotype.

Qualitative and quantitative analyses of the volatile constituents from resin of Protium heptaphyllum (Aubl.) Marchand subsp. ulei (Swat) Daly (PHU), and Protium heptaphyllum (Aubl.) Marchand subsp. heptaphyllum (PHH), Burseraceae were performed using GC-MS and GC-FID. The resins were collected around the city of Cruzeiro do Sul, state of Acre, Brazil. Essential oils from the two subspecies were extracted by hydrodistillation with a yield of 8.6% (PHU) and 11.3% (PHH); the main components were terpinolene (42.31%) and p-cymene (39.93%) for subspecies ulei (PHU) and heptaphyllum (PHH), respectively.

The chemical composition of the essential oil from the whole plant of Acalypha segetalis Muell. Arg. was analyzed by GC and GC/MS. Nineteen volatile constituents were identified. The main compounds were α-pinene (8.5%), neophytadiene, isomer II (14.7%) and neophytadiene, isomer III (33.6%). Toxicity and larvicidal assays revealed that the plant had LC50 values of 14.0 μg/mL and 45.4 μg/mL respectively.
