Stink bugs (Heteroptera, Pentatomidae) and an unique host plant in the Brazilian subtropics
Panizzi, Ant?nio Ricardo;Grazia, Jocélia;
Iheringia. Série Zoologia , 2001, DOI: 10.1590/S0073-47212001000100003
Abstract: stink bugs are seed/fruit sucking insects feeding on an array of host plants. among them, an exotic tree called privet, ligustrum lucidum ait. (oleaceae), is very common in the urban areas of the brazilian subtropics, where it is utilized as food source and shelter for over a decem species of bugs, year round. the species composition, their performance and abundance on this host, and possible causes for this association are discussed and illustrated.
Rostrum length, mandible serration, and food and salivary canals areas of selected species of stink bugs (Heteroptera, Pentatomidae)
Depieri, Rogério A.;Panizzi, Ant?nio R.;
Revista Brasileira de Entomologia , 2010, DOI: 10.1590/S0085-56262010000400008
Abstract: laboratory studies were conducted to compare rostrum length morphology of mandible serration and area of food and salivary canals of dichelops melacanthus (dallas) (dm), euschistus heros (f.) (eh), nezara viridula (l.) (nv), and piezodorus guildinii (westwood) (pg) (heteroptera: pentatomidae). nv showed the longest (5.9 mm) and pg the shortest (3.5 mm) rostrum length; dm and eh were intermediate. length and width of mandible tip areas holding serration was bigger for nv (106.0 and 30.2 μm, respectively) and smaller for pg (71.1 and 23.7 μm), with all species having four central teeth and three pairs of lateral teeth. the inner mandible surface showed squamous texture. cross-section of food and salivary canals (fc and sc) indicated greater area for nv and dm compared to eh and pg; however, the ratio fc/sc, yielded the highest relative area for pg.
Stink bugs on soybean in northeastern Brazil and a new record on the southern green stink bug, Nezara viridula (L.) (Heteroptera: Pentatomidae)
PANIZZI, ANT?NIO R.;
Neotropical Entomology , 2002, DOI: 10.1590/S1519-566X2002000200023
Abstract: during march-april 2001, a survey of pentatomids associated with soybean [glycine max (l.) merrill] was conducted at northeastern brazil (balsas county ? maranh?o state - latitude 7°31's, longitude 46°02'w). the majority of the phytophagous bugs (82.4%) belonged to the species euschistus heros (f.). other six species of bugs were collected in much lower numbers (<5.0%). among them, the exotic species, nezara viridula (l.), was intercepted in this area for the first time, expanding its distribution in the neotropical region.

Journal of Central European Agriculture , 2002,
Abstract: The southern green stink bug Nezara viridula (L.) (Heteroptera: Pentatomidae) is a global pest of considerable ecological, agricultural and economical interest. The ancestral home of this species is supposed to be Africa and/or Mediterranean and presumably it was spread worldwide during the last two centuries with human trade and agriculture. Bugs found today on different continents do not differ morphologically, however there are substantial differences in their mating behaviour. We used horizontal starch gel electrophoresis to determine the suitability of biochemical markers for assessment of genetic variation between geographically isolated populations of N. viridula. The initial survey of populations from Slovenia, France, French West Indies and Brazil resulted in the resolution of polymorphic banding patterns within the following enzyme systems: GPI, IDH, MDH, ME, MPI and PGM. Results indicate there are consistent differences among tested populations.
Synthesis of the minor sex pheromone component of two brazilian soybean stink bugs (Het.: Pentatomidae), and an analogue compound

Journal of the Brazilian Chemical Society , 2000, DOI: 10.1590/S0103-50532000000600004
Abstract: the stink bugs euschistus heros and piezodorus guildinii (heteroptera: pentatomidae) are economically important soybean pests in brazil. an intriguing characteristic of these species is the fact that they use the same chemical compounds as sex pheromone, e.g., methyl 2,6,10-trimethyldodecanoate (1) (minor) and methyl 2,6,10-trimethyltridecanoate (2). in order to investigate the specific biological function of these molecules and to increase the knowledge of the communication system of each species, we have synthesized the minor component 1 and an analogue compound, methyl 2,6,10-trimethyltetradecanoate (3). these compounds will be tested on indoor bioassay, in addition with the previously synthesized major component 2.

First cases of exclusive paternal care in stink bugs (Hemiptera: Pentatomidae)
Requena, Gustavo S.;Nazareth, Taís M.;Schwertner, Cristiano F.;Machado, Glauco;
Zoologia (Curitiba) , 2010, DOI: 10.1590/S1984-46702010000600026
Abstract: we describe paternal care in two pentatomid bugs, lopadusa (lopadusa) augur st?l, 1860 and edessa nigropunctata berg, 1884. field and laboratory observations showed that males remain with their eggs and early hatched nymphs, while females abandon the eggs after oviposition. guarding males defensive behaviors towards their clutches were similar to those described for guarding females of pentatomids. since there is no detailed information on the internal phylogeny of pentatomidae, it is not possible to make a robust inference on whether paternal care in l. augur and e. nigropunctata has arisen independently or not. if the latter, the two new cases of paternal care we describe here represent the fifth event of independent evolution of this rare behavioral trait in heteroptera.
The chemical volatiles (Semiochemicals) produced by neotropical stink bugs (Hemiptera: Pentatomidae)
Moraes, Maria C.B.;Pareja, Martín;Laumann, Raúl A.;Borges, Miguel;
Neotropical Entomology , 2008, DOI: 10.1590/S1519-566X2008000500001
Abstract: in recent years the growing concern about environmental changes and how we are using the natural resources have triggered a search for natural products as alternatives to synthetic pesticides. the stink bugs produce a wide variety of chemical compounds (semiochemicals) that show potential to manage these insects. the stink bugs chinavia impicticornis (st?l), c. ubica (rolston), dichelops melacanthus (dallas), euschistus heros (f.), piezodorus guildinii (westwood), thyanta perditor (westwood) and tibraca limbativentris (st?l) had their blends of defensive compounds evaluated both qualitative and quantitatively. the main compounds identified on the glands of brazilian stink bugs are: 2-alkenals, mainly the e isomer; saturated aliphatic hydrocarbons; and 4 oxo-(e)-2-alkenals. the first sex attractant determined from a stink bug was obtained from nezara viridula l., and consists on a mix of two isomers cis - and trans bisabolene-epoxides. later the soybean stink bug e. heros was also studied and its sex attractant was identified as three esters methyl: 2,6,10-trimethyldecanoate, methyl 2,6,10-trimethyldodecanoate, and methyl e2, z4-decadienoate. recently, three new brazilian sting bugs were studied and had their sex attractant elucidated. males of t. perditor produce the ester, methyl 2e,4z,6z-decatrienoate. whereas, the stink bug, p. guildinii has as sexual pheromone, the sesquiterpene β-sesquiphellandrene, and the stink bug t. limbativentris produces as sex attractant the zingiberenol. in this review we discuss the advances obtained on the behaviour and identification of sex and defensive compound of stink bugs from brazilian crops and the application of this knowledge to manage the stink bugs.
Alarm pheromone system of stink bug Piezodorus guildinii (Heteroptera: Pentatomidae)
Zarbin, Paulo H. G.;Borges, Miguel;Santos, Alcindo A. dos;Oliveira, Alfredo R. M. de;Simonelli, Fábio;Marques, Francisco de A.;
Journal of the Brazilian Chemical Society , 2000, DOI: 10.1590/S0103-50532000000400017
Abstract: the compounds utilized by the soybean stink bug piezodorus guildinii as alarm pheromone were characterized by analysis of the chemical composition of the metathoracic scent gland secretions from adult bugs. in addition to characteristic hydrocarbons, (e)-2-hexenal and (e)-4-oxo-2-hexenal were detected as major constituents. these compounds were previously described as alarm pheromone in several other pentatomid species.
