Differences in larval emergence chronotypes for sympatric Rhagoletis brncici Frías and Rhagoletis conversa (Bréthes) (Diptera, Tephritidae)

ABSTRACT In central Chile, Rhagoletis brncici and R. conversa, can be found in sympatry, associated with the fruit of their native host plants: Solanum tomatillo and S. nigrum (Solanaceae), respectively. Third-stage larvae must emerge from its host in search of pupation sites, and during this period larvae must find an appropriate pupation microhabitat while avoiding predation and adverse abiotic factors. In this study, we explored whether these sympatric species differ in terms of the timing of their larval exit from the host fruit in search of pupation sites. Field-collected fruits from host plants were checked daily for larval emergence, within 24 h, under laboratory conditions, in order to determine the time of the event. We found that these species...

ABSTRACT A new genus and species of gall midge, Haplopappusmyia gregaria, is described and illustrated (larva, pupa, male, and female). This species induces apical galls on Haplopappus foliosus (Asteraceae), an endemic shrub from central Chile. The specimens were collected at La Ligua Municipality, Petorca Province, Valparaiso region, Chile, during spring of 2011-2014. This area corresponds to one of the fifth Mediterranean Matorral biome, considered among Earth's biodiversity hotspots. The new genus is characterized by presenting lateral margin of antennal scape with a mesal reentrance; four-segmented palpus, one-toothed tarsal claws, R5 straight, reaching C anterior to wing apex; male seventh and eighth tergites lacking sclerotization mesally, beyond...

Distribution, habitat use and plant associations of Moluchia brevipennis (Saussure, 1864) (Blattodea: Ectobiidae): an endemic cockroach from Chilean Mediterranean Matorral biome

ABSTRACT Wild cockroaches are often described as abundant and diverse insects from wet tropical zones; however, they can also be found in arid and semiarid areas. It is proposed that in these drier environments cockroach survival may dependent on its tight association with native plant species. In this work, using bait trapping and active collection methods, we surveyed cockroach species along central Chile coastal scrubland; the southern limit of the semiarid Mediterranean Matorral biome in the Neotropical Region (32° S). Based on morphological and DNA barcoding methods we found that our collected cockroaches belonged to native species Moluchia brevipennis (Saussure, 1864) (Blattodea: Ectobiidae). Furthermore, thanks to field sampling, we noticed for the...
