Packauskas1 Abstract Forty eight species of Pentatomidae are listed as occurring in the state of Kansas, nine of these are new state records. A key to all species known from the state of Kansas is given, along with some notes on new state records. ____________________ The family Pentatomidae, comprised of mainly phytophagous and a few predaceous species, is one of the largest families of Heteroptera. Some of the phytophagous species have a wide host range and this ability may make them the most economically important family among the Heteroptera (Panizzi et al. 2000). As a group, they have been found feeding on cotton, nuts, fruits, veg- etables, legumes, and grain crops (McPherson 1982, McPherson and McPherson 2000, Panizzi et al 2000).

Seven stink bug species were recorded, however three species, represented in the samples by both adults and nymphs, accounted for approximately 97% of the 257 stink bugs collected. Anaxilaus vesiculosus (Herrich-Schaeffer) dominated the fauna (84%), whilst Eysarcoris trimaculatus (Distant) and Nezara viridula (L.) constituted 9% and 4% of captures respectively. Although stink bug densities were very low and unlikely to cause significant damage to the crops examined, there was a high level of variability between crops and also between seasons, with a six-fold increase in the average number of bugs collected per crop in the second year of the study. Field-collected A.vesiculosus adults placed on a caged rice plant survived for up to 20 days. Nymphs that emerged from eggs laid on the plant were reared through to adulthood without any alternative food sources being supplied. Hulled grain from the exposed plant showed the characteristic blemishes associated with stink bug feeding.

    EENY-523 A Stink Bug Euschistus quadrator Rolston (Insecta: Hemiptera: Pentatomidae)1 Sara A. Brennan, Joseph Eger, and Oscar E. Liburd2 Introduction in the membranous area of the hemelytra, a characteristic present in other Euschistus species. Euschistus quadrator Rolston was described in 1974, with specimens from Mexico, Texas, and Louisiana. Euschistus quadrator was not found in Florida until 1992. It has since spread throughout the state as well as becoming an agricultural pest of many fruit, vegetable, and nut crops in the southeastern United States. It has a wide host range, but is most commonly found in cotton, soybean and corn. Euschistus quadrator has recently become a more promi- nent pest with the introduction of crops such as Bt cotton and an increase in the usage of biorational or reduced-risk pesticides. Distribution Euschistus quadrator is originally from Texas and Mexico, and has since been reported in Louisiana, Georgia, and Florida. Description Figure 1.

An invasive species, the brown marmorated stink bug, Halyomorpha halys (Sta˚ l), is spreading through the region. However, little is known about the complex of stink bug species associ- ated with corn and soybean in the midwestern United States. In this region, particularly in the more northern states, stink bugs have historically caused only infrequent impacts to these crops. To prepare growers and agri- cultural professionals to contend with this new threat, we provide a review of stink bugs associated with soybean and corn in the midwestern United States.

Postal: 02372 Cep.: 70849-970, Brasilia, DF, Brazil (Received October 22, 1993; accepted January 6, 1994) Abstract--Males of the Central American stink bug species, Euschistus obscurus, produce an attractant pheromone composed of a blend of com- pounds characteristic of North American Euschistus spp. and the South Amer- ican soybean pest, E. heros. The range of E. obscurus extends into the southern United States, the species is easy to rear, and males produce an exceptionally large quantity of pheromone (>0.5 /zg/day/male). These factors made E. obscurus useful for characterizing the novel pheromone components of E. heros without importing this pest species into the United States. Euschistus obscurus males produce methyl (2E,4Z)-decadienoate (61%) in abundance, which is characteristic of North American species, and methyl 2,6,10-tri- methyltridecanoate (27%), the main male-specific ester of E. heros. The chi- rality of Euschistus spp. methyl-branched esters, and field activity of synthetic formulations, remain to be determined.

P.R. 100 Special issue (1): (2016) ABSTRACT Pentatomoidea fauna for Puerto Rico and its adjacent islands is documented as part of a revised account of Heteroptera on these islands. There are 71 species in six families of Pentatomoidea known from Puerto Rico: Cydnidae (11); Pentatomidae (48) including Asopinae (8), Pentatominae (37), Discocephalinae (1), and Edessinae (2); Tessaratomidae (1); Scutelleridae (8); Megarididae (1); and Corimelaenidae (2). Of this total, seven represent new state records for Puerto Rico. Taxonomic accounts include synonymies, known distribution, lists of hosts, and a listing of specimens examined. Regional taxonomical keys are provided for the identification of taxa included. Color plates for most species are also included.
