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).

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.

It seldom plays a major role in the natural control of insects in Florida, but its prey includes a number Description of economically important species. Adults The length of males is approximately 12 mm, with a head width of 2.3 mm and a humeral width of 6.4 mm. The length of females is 12 to 17 mm, with a head width of 2.4 mm and a humeral width of 7.2 mm. Euthyrhynchus floridanus (Figure 2) normally can be distinguished from all other stink bugs in the southeastern United States by a red- dish spot at each corner of the scutellum outlined against a blue-black to purplish-brown ground color. Variations occur that might cause confusion with somewhat similar stink bugs in several genera, such as Stiretrus, Oplomus, and Perillus, but these other bugs have obtuse humeri, or at least lack the distinct humeral spine that is present in adults of Euthyrhynchus.

    Pažoutová S. (2002) Evolutionary strategy of Claviceps. In: Clavicipitalean Fungi: Evolutionary Biology, Chemistry, Biocontrol and Cultural Impacts. White JF, Bacon CW, Hywel-Jones NL (Eds.) Marcel Dekker, New York, Basel, pp.329-354. 11 The Evolutionary Strategy of Claviceps Sylvie Pažoutová Institute of Microbiology, Czech Academy of Sciences Vídeòská 1083, 142 20 Prague, Czech Republic 1. INTRODUCTION Members of the genus Claviceps are specialized parasites of grasses, rushes and sedges that specifically infect florets. The host reproductive organs are replaced with a sclerotium. However, it has been shown that after artificial inoculation, C. purpurea can grow and form sclerotia on stem meristems (Lewis, 1956) so that there is a capacity for epiphytic and endophytic growth. C. phalaridis, an Australian endemite, colonizes whole plants of pooid hosts in a way similar to Epichloë and it forms sclerotia in all florets of the infected plant, rendering it sterile (Walker, 1957; 1970). Until now, about 45 teleomorph species of Claviceps have been described, but presumably many species may exist only in anamorphic (sphacelial) stage and therefore go unnoticed. Although C. purpurea is type species for the genus, it is in many aspects untypical, because most Claviceps species originate from tropical regions, colonize panicoid grasses, produce macroconidia and microconidia in their sphacelial stage and are able of microcyclic conidiation from macroconidia. Species on panicoid hosts with monogeneric to polygeneric host ranges predominate. 329 2. PHYLOGENETIC TREE We compared sequences of ITS1-5.8S-ITS2 rDNA region for 19 species of Claviceps, Database sequences of Myrothecium atroviride (AJ302002) (outgroup from Bionectriaceae), Epichloe amarillans (L07141), Atkinsonella hypoxylon (U57405) and Myriogenospora atramentosa (U57407) were included to root the tree among other related genera.

    Further Screening of Entomopathogenic Fungi and Nematodes As Control Agents for Drosophila Suzukii

    insects Article Further Screening of Entomopathogenic Fungi and Nematodes as Control Agents for Drosophila suzukii Andrew G. S. Cuthbertson * and Neil Audsley Fera, Sand Hutton, York YO41 1LZ, UK; [email protected] * Correspondence: [email protected]; Tel.: +44-1904-462-201 Academic Editor: Brian T. Forschler Received: 15 March 2016; Accepted: 6 June 2016; Published: 9 June 2016 Abstract: Drosophila suzukii populations remain low in the UK. To date, there have been no reports of widespread damage. Previous research demonstrated that various species of entomopathogenic fungi and nematodes could potentially suppress D. suzukii population development under laboratory trials. However, none of the given species was concluded to be specifically efficient in suppressing D. suzukii. Therefore, there is a need to screen further species to determine their efficacy. The following entomopathogenic agents were evaluated for their potential to act as control agents for D. suzukii: Metarhizium anisopliae; Isaria fumosorosea; a non-commercial coded fungal product (Coded B); Steinernema feltiae, S. carpocapsae, S. kraussei and Heterorhabditis bacteriophora. The fungi were screened for efficacy against the fly on fruit while the nematodes were evaluated for the potential to be applied as soil drenches targeting larvae and pupal life-stages. All three fungi species screened reduced D. suzukii populations developing from infested berries. Isaria fumosorosea significantly (p < 0.001) reduced population development of D. suzukii from infested berries. All nematodes significantly reduced adult emergence from pupal cases compared to the water control. Larvae proved more susceptible to nematode infection. Heterorhabditis bacteriophora proved the best from the four nematodes investigated; readily emerging from punctured larvae and causing 95% mortality.

    Aphid-Parasitoid (Insecta) Diversity and Trophic Interactions in South Dakota

    Proceedings of the South Dakota Academy of Science, Vol. 97 (2018) 83 APHID-PARASITOID (INSECTA) DIVERSITY AND TROPHIC INTERACTIONS IN SOUTH DAKOTA Abigail P. Martens* and Paul J. Johnson Insect Biodiversity Lab South Dakota State University Brookings, SD 57007 *Corresponding author email: [email protected] ABSTRACT Parasitoid wasps of the subfamily Aphidiinae (Hymenoptera: Braconidae) specialize on aphids (Hemiptera: Aphididae) as hosts. The diversity of known and probable aphidiine wasps from South Dakota is itemized, with represen- tation by 13 genera and 42 species, 43% of which are probably adventitious. The wasps and aphids are central to various combinations of multitrophic relationships involving host plants and secondary parasitoids. Selected native and introduced aphid host taxa were quantitatively and qualitatively collected from diverse native and crop host plants in eastern South Dakota and western Iowa. Wasps were reared to confirm plant association, host aphid association, taxonomic diversity, and native or introduced status of the wasps. Acanthocaudus tissoti (Smith) and Aphidius (Aphidius) ohioensis (Smith) were found together on the native aphid Uroleucon (Uroleucon) nigrotuberculatum (Olive), a new host aphid species for both wasps on Solidago canadensis L. (Asterales: Asteraceae). The native waspLysiphlebus testaceipes (Cresson) was repeatedly reared in mas- sive numbers from mummies of invasive Aphis glycines Matsumura on soybean, Glycine max (L.) Merr. This wasp was also reared from the non-nativeAphis nerii Boyer de Fonscolombe and the native Aphis asclepiadis Fitch, both on Asclepias syriaca L. The introduced wasp Binodoxys communis (Gahan) was not recovered from any Aphis glycines population. Hyperparasitoids from the genus Dendrocerus Ratzeburg (Hymenoptera: Megaspilidae), and the pteromalid (Hymenoptera: Pteromalidae) genera Asaphes Walker, and Pachyneuron Walker were reared from mummies of Uroleucon (Uroleucon) nigrotuberculatum parasitized by either Acanthocaudus tissoti or Aphidius (Aphidius) ohioensis.
