LASIODERMA SERRICORNE (COLEOPTERA: ANOBIIDAE) IN STORED MATRICARIA RECUTITA (ASTERACEAE) IN BRAZIL

Insects pests of stored products and by-products are extending their feeding preferences to new items. We report for the first time in Brazil the feeding and reproduction of the cigarette beetle, Lasioderma serricorne F. (Coleoptera: Anobiidae) on stored chamomile, Matricaria recutita L. (Asteraceae). One intact package (10 cm wide x 15 cm long) of M. recutita infested by L. serricorne was purchased in a supermarket in Vicosa, Minas Gerais, Brazil. In this sample this insect had fed on the dried parts (inflorescences and rods), which made the product unfit for human consumption. This 20 g sample included 101 live and 4 dead Lasioderma serricorne. Circumstantial evidence suggested that the infested material was probably harvested from an infested field in Apr 2013 and packaged with L. serricorne eggs, and that these had developed into the adults found in the package.

Meiotic behavior of 18 species from eight families of terrestrial Heteroptera

Insects of the suborder Heteroptera are known for their odor, for being pests, or for being disease carriers. To gain better insight into the cytogenetic characteristics of heteropterans, 18 species of terrestrial Heteroptera belonging to eight families were studied. The presence of heteropycnotic corpuscles during prophase I, terminal or interstitial chiasmas, telomeric associations between chromosomes, ring disposals of autosomes during metaphase, and late migrations of the sex chromosomes during anaphase were analyzed. These features showed identical patterns to other species of Heteroptera previously described in the literature. Another studied characteristic was chromosome complements. The male chromosome complements observed were 2n = 12 chromosomes [10A + XY, Galgupha sidae (Amyot & Serville) (Corimelaenidae) and Pachycoris torridus (Scopoli) (Scutelleridae)]; 2n = 13 [10A + 2m + X0, Harmostes serratus (Fabricius), Harmostes apicatus (Stål), Jadera haematoloma (Herrich-Schaeffer), Jadera sanguinolenta (Fabricius), Jadera sp. (Rhopalidae)], and Neomegalotomus parvus (Westwood) (Alydidae); 2n = 13 [12A + X0, Stenocoris furcifera (Westwood) (Alydidae); 2n = 14 [12A + XY, Dictyla monotropidia (Stål) (Tingidae)]; 2n = 19 [18A + X0, Acanonicus hahni (Stål) (Coreidae)]; 2n = 21 [18A + 2m + X0, Acanthocephala sp. (Dallas) (Coreidae)]; 2n = 27 [24A + 2m + X0, Anisoscelis foliacea marginella (Dallas) (Coreidae)]; 2n = 18 [16A + XY, Oncopeltus fasciatus (Dallas) (Lygaeidae)]; 2n = 17 [14A + X1X2Y, Oxycarenus hyalinipennis (Costa) (Lygaeidae)]; 2n = 16 [12A + 2m + XY, Pachybrachius bilobatus (Say) (Lygaeidae)]; 2n = 26 [24A + XY, Atopozelus opsinus (Elkins) (Reduviidae)]; and 2n = 27 [24A + X1X2Y, Doldina carinulata (Stål) (Reduviidae)]. The diversity of the cytogenetic characteristics of Heteroptera was reflected in the 18 studied species. Thus, this study extends the knowledge of these characteristics, such as the variations related to chromosome complements, sex chromosome systems, and meiotic behavior.
