Effect of Feeding on Three Eucalyptus Species on the Development of Brontocoris tabidus (Het.: Pentatomidae) Fed with Tenebrio molitor (Col.: Tenebrionidae)

Attack behavior of Podisus rostralis (Heteroptera: Pentatomidade) adults on caterpillars of Bombyx mori (Lepidoptera: Bombycidae)

“…rostralis alternated fast movements with periods of immobility, which was similar with that observed for P. nigrispinus (Carvalho et al, 1995), but without a behaviour with defined stages. P. rostralis significantly increased movements of antennas after finding the prey which was a typical attacking behavior of predatory Heteroptera (Cohen, 1995;Zanuncio et al, 2000). (De Clercq, 2000).…”

“…Podisus are general predators that feed on Lepidoptera (Lemos et al, 2001 and2003), Coleoptera (Biever and Chauvin, 1992;HoughGoldstein and McPherson, 1996), Homoptera, Orthoptera and Diptera (Molina-Rugama et al, 1997 and1998). Podisus rostralis (Stäl) (Heteroptera, Pentatomidae) is found in most countries of South America (Thomas, 1992), but unlike other predatory Pentatomidae (Molina-Rugama et al, 1997;Zanuncio et al, 2000 andMedeiros et al, 2000;Lemos et al, 2001 and2003) few studies have been developed with this species. The development of immature of P. rostralis with three alternative preys (Matos Neto et al, 1999) and reproductive strategy of its females with different feeding intervals (Molina-Rugama et al, 1998) were studied in laboratory.…”

Biochemical and morphological aspects of salivary glands of the predator Brontocoris tabidus (Heteroptera: Pentatomidae)

“…EOD is a cyclical process, consisting of three phases: injection of toxins and/or digestive enzymes, initial digestion of the food and ingestion of the liquefied material (Cohen, 1993(Cohen, , 1995. Another important aspect of B. tabidus is its need of plant feeding that can improve some of their characteristics such as oviposition rate, nymph development and survival (Zanuncio et al, 2000), what has also been reported for other Heteroptera (Saavedra et al, 1997;Zeng and Cohen, 2000;Boyd, 2003). Toxins and/or digestive enzymes involved in EOD can be produced in specialized structures such as labial and maxillary glands or in the gut like in spiders and beetles.…”

“…Use of chemical products to control had caused damage to the environment and to man increasing the importance of natural enemies such as Heteroptera predators (Bueno and Berti, 1991;Zanuncio et al, 1994a) in programs of integrated pest management (Molina-Rugama et al 1997, 1998. Pentatomidae presents species with high potential to control insect pests such as those of Asopinae including Podisus maculiventris (Say) and Perillus bioculatus (F.) in North America and Europe, Podisus nigrispinus (Dallas) (Zanuncio et al, 2001) and Brontocoris tabidus (Signoret) (Zanuncio et al, 2000) in South America, and Eocanthecona furcellata (Wolff) in the Southeast of Asia and India (De Clercq, 2000). Brontocoris tabidus presents attack mechanism consisting of stylet insertion in the prey body causing progressive paralysis, allowing feeding (J.C. Zanuncio, personal observation).…”

The Reproductive Tract of the Males of the Zoophytophagous Predator <i>Brontocoris tabidus</i> (Signoret) (Heteroptera: Pentatomidae) with Different Diets and Ages

“…Podisus nigrispinus (Dallas), Brontocoris tabidus (Signoret) and Supputius cincticeps (Stäl) (Heteroptera: Pentatomidae) in South America (Zanuncio et al, 2000;Lemos et al, 2003;2005a;2005b), Eocanthecona furcellata (Wolff) (Heteroptera: Pentatomidae) in the Southeast Asia and India (De Clerq, 2000), Troilus luridus F. and Zicrona caerulea L in European Russia (Shestakov, 2008) and Picromerus bidens (Linnaeus) distributed in the western Palearctic region (Mahdian et al, 2008).…”
