Brailovsky: A Revision of the Genus Amblyomia 475 A REVISION OF THE GENUS AMBLYOMIA STÅL (HETEROPTERA: COREIDAE: COREINAE: LEPTOSCELINI) HARRY BRAILOVSKY Instituto de Biología, UNAM, Departamento de Zoología, Apdo Postal 70153 México 04510 D.F. México ABSTRACT The genus Amblyomia Stål is revised and two new species, A. foreroi and A. prome- ceops from Colombia, are described. New host plant and distributional records of A. bifasciata Stål are given; habitus illustrations and drawings of male and female gen- italia are included as well as a key to the known species. The group feeds on bromeli- ads. Key Words: Insecta, Heteroptera, Coreidae, Leptoscelini, Amblyomia, Bromeliaceae RESUMEN El género Amblyomia Stål es revisado y dos nuevas especies, A. foreroi y A. prome- ceops, recolectadas en Colombia, son descritas. Plantas hospederas y nuevas local- idades para A. bifasciata Stål son incluidas; se ofrece una clave para la separación de las especies conocidas, las cuales son ilustradas incluyendo los genitales de ambos sexos. Las preferencias tróficas del grupo están orientadas hacia bromelias. Palabras clave: Insecta, Heteroptera, Coreidae, Leptoscelini, Amblyomia, Bromeli- aceae The neotropical genus Amblyomia Stål was previously known from a single Mexi- can species, A. bifasciata Stål 1870. In the present paper the genus is redefined to in- clude two new species collected in Colombia. This genus apparently is restricted to feeding on members of the Bromeliaceae, and specimens were collected on the heart of Ananas comosus and Aechmea bracteata. -

Several success cases of biological control can be found in the tropics around the world. The classical biological control has been applied with greater emphasis in Australia and Latin America, with many success cases of exotic natural enemies’ introduction for the control of exotic pests. Augmentative biocontrol is used in extensive areas in Latin America, especially in the cultures of sugar cane, coffee, and soybeans. -

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. In addition, species of these genera Figure 1.

Crop Profile for Snap Beans in Florida
Crop Profile for Beans (Snap) in Florida Prepared: October 8, 1999 Revised: March 2003, September 2012 Production Facts • Florida is ranked first nationally in the production, acreage and total value of fresh market snap beans (1). • The state's snap bean crop contributes 44 percent of the U.S. total in terms of production and 27.4 percent in terms of cash receipts (1). During the winter months (January, February and March), Florida produces 100 percent of the fresh market snap beans grown in the U.S. (1,2). • In 2009-2010, Florida growers produced 193.2 million pounds of snap beans, with a value of $0.69 per pound and a total value of $135 million. Snap beans were planted on 36,400 acres, and 32,200 acres were harvested, yielding an average of 6,000 pounds per acre (1,2). • In 2007, there were 373 snap bean producing farms in Florida. Of those farms, 68.6 percent produced snap beans on less than 5 acres, as a group representing 0.4 percent of the state's total snap bean acreage. An additional 11.5 percent maintained between 5 and 49 acres of snap beans (representing 1.85 percent of the state's snap bean acreage), 8.6 percent planted between 50 and 249 acres (10.7 percent of acreage), 4.8 percent planted between 250 and 499 acres (13.8 percent of acreage), and 6.4 percent planted greater than 500 acres (73.2 percent of acreage) (3). • During the 2009-2010 season, snap beans ranked 3rd and 1st for harvested acreage and value of production, respectively, for Florida's diverse vegetable commodities. -

Spined Soldier Bug
Beneficial Species Profile Photo credit: Russ Ottens, University of Georgia, Bugwood.org; Gerald J. Lenhard, Louisiana State University, Bugwood.org Common Name: Spined soldier bug Scientific Name: Podisus maculiventris Order and Family: Hemiptera; Pentatomidae Size and Appearance: Length (mm) Appearance Egg 1 mm Around the operculum (lid/covering) on the egg there are long projections; eggs laid in numbers of 17 -70 in oval masses; cream to black in color. Larva/Nymph 1.3 – 10 mm 1st and 2nd instars: black head and thorax; reddish abdomen; black dorsal and lateral plates. Younger instars are gregarious; cannibalistic. 3rd instar: black head and thorax; reddish abdomen with black, orange, and white bar-shaped and lateral markings 4th instar: similar to 3rd instar; wing pads noticeable 5th instar: prominent wing pads; mottled brown head and thorax; white or tan and black markings on abdomen. Adult 11 mm Spine on each shoulder; mottled brown body color; females larger than males; 2 blackish dots at the 3rd apical (tip) of each hind femur; 1-3 generations a year. Pupa (if applicable) Type of feeder (Chewing, sucking, etc.): Nymph and adult: Piercing-sucking Host/s: Spined soldier bugs are predators and feed on many species of insects including the larval stage of beetles and moths. These insects are found on many different crops including alfalfa, soybeans, and fruit. Some important pest insect larvae prey include Mexican bean beetle larvae, European corn borer, imported cabbageworm, fall armyworm, corn earworm, and Colorado potato beetle larvae. If there is not enough prey, the spined soldier bug may feed on plant juices, but this does not damage the plant. -
Discrimination Between Eggs from Stink Bugs Species in Europe Using MALDI-TOF MS
insects Article Discrimination between Eggs from Stink Bugs Species in Europe Using MALDI-TOF MS Michael A. Reeve 1,* and Tim Haye 2 1 CABI, Bakeham Lane, Egham, Surrey TW20 9TY, UK 2 CABI, Rue des Grillons 1, CH-2800 Delémont, Switzerland; [email protected] * Correspondence: [email protected] Simple Summary: Recent globalization of trade and travel has led to the introduction of exotic insects into Europe, including the brown marmorated stink bug (Halyomorpha halys)—a highly polyphagous pest with more than 200 host plants, including many agricultural crops. Unfortunately, farmers and crop-protection advisers finding egg masses of stink bugs during crop scouting frequently struggle to identify correctly the species based on their egg masses, and easily confuse eggs of the invasive H. halys with those of other (native) species. To this end, we have investigated using matrix-assisted laser desorption and ionization time-of-flight mass spectrometry (MALDI-TOF MS) for rapid, fieldwork-compatible, and low-reagent-cost discrimination between the eggs of native and exotic stink bugs. Abstract: In the current paper, we used a method based on stink bug egg-protein immobilization on filter paper by drying, followed by post-(storage and shipping) extraction in acidified acetonitrile containing matrix, to discriminate between nine different species using MALDI-TOF MS. We obtained 87 correct species-identifications in 87 blind tests using this method. With further processing of the unblinded data, the highest average Bruker score for each tested species was that of the cognate Citation: Reeve, M.A.; Haye, T. reference species, and the observed differences in average Bruker scores were generally large and the Discrimination between Eggs from errors small except for Capocoris fuscispinus, Dolycoris baccarum, and Graphosoma italicum, where the Stink Bugs Species in Europe Using average scores were lower and the errors higher relative to the remaining comparisons. -
