A parasitoid wasp, Trissolcus basalis (Wollaston), was recorded parasitizing eggs of the invasive stink bug Halyomorpha halys (Stål) in United States. This is first record this species fresh and frozen H. States.First
Data from long-term Tribolium castaneum (Herbst) pheromone trapping programs in two flour mills was used to evaluate the impact of structural fumigations (n = 23) on pest populations. The differed mean number beetles captured and proportion traps with captures one or more beetles, but reduced after implementing a intensive integrated management program. Mean per trap increased by 52.7 +/- 8.2 24.8 4.7% monitoring period next decreased 84.6 4.6 71.0 5.1% when fumigation occurred between...
A parasitoid wasp, Trissolcus solocis Johnson, was recorded parasitising eggs of the invasive stink bug Halyomorpha halys (Stål), in United States. This is first record this species H. halys.First States and T. Alabama.
Reliable monitoring of the invasive Halyomorpha halys abundance, phenology and geographic distribution is critical for its management. adult nymphal captures on clear sticky traps in black pyramid were compared 18 states across Great Lakes, Mid-Atlantic, Southeast, Pacific Northwest Western regions United States. Traps baited with commercial lures containing H. pheromone synergist, deployed at field sites bordering agricultural or urban locations host plants. Nymphal greater than those...
Drosophila suzukii Matsumura (Diptera: Drosophilidae), an economically important pest of blueberry and other thin-skinned fruits, persists prolifically reproduces under seemingly lethal climatic conditions in the field. However, behavioral physiological mechanisms employed by D. to tolerate such extreme field are unknown. The primary objective this project was investigate diel periodicity their reproductive success as related factors temperature relative humidity. Results show that...
The invasive brown marmorated stink bug, Halyomorpha halys, is present in the Piedmont and expanding into Coastal Plains Regions of southeastern US. Consequently, this study was conducted to evaluate parasitism predation H. halys sentinel egg masses by native parasitoids predators woodland habitats orchard, vineyard, row, vegetable crops alongside these Alabama Georgia 2017 2018. Ten primary parasitoid species, including two new records, one hyperparasitoid emerged from eggs. Trissolcus...
Abstract During the last decade, sorghum aphid ( Melanaphis sorghi ), previously identified as sugarcane sacchari became a serious pest of sorghum, spreading to all sorghum‐producing regions in United States, Mexico, and South America, where crop losses 50%–100% have been reported. Developing cultivars with resistance this insect is most sustainable strategy for long‐term management. To design resistance, comprehensively understanding mechanisms underlying survival, host plant aphid–sorghum...
Abstract Melanaphis sorghi is a serious economically important pest of sorghum, Sorghum bicolor (L.), across the southern USA. Therefore, developing and refining integrated strategies that provide effective control key to management this pest. The current study examined influence nitrogen (N) fertilization, sorghum cultivar insecticide applications on M. grain yield at Tifton, Georgia (31.5120° N, 83.6434° W). Field trials with three treatments (untreated control, flupyradifurone in-furrow...
Contact toxicity of a commercial bacterial fermentation insecticide, spinosad, to adults eight stored-product beetles was evaluated on four different surfaces. Aqueous spinosad suspension sprayed with an airbrush 30.5-cm2 surfaces concrete, galvanized steel, unwaxed floor tile, or waxed tile obtain deposits 0.05 0.1 mg (AI)/cm2. Control were distilled water. Approximately 24 h after water application, 30 adult confined, by species, each untreated and spinosad-treated surface. Insects exposed...
Abstract Spinosad, a reduced‐risk commercial insecticide derived from bacterial fermentation product, possesses both contact and oral toxicities against insects. Contact toxicity of spinosad to adults Rhyzopertha dominica (F), Sitophilus oryzae (L), Tribolium castaneum (Herbst) was evaluated by exposure for 24 or 48 h treated glass Petri dishes. Adults were exposed different deposits (0.001–0.79 mg cm −2 ) in 24‐h tests 0, 0.0016 0.016 48‐h tests. most susceptible 24‐ tests, followed S , T ....
Structural fumigations of food processing plants to manage stored-product insects has been a major component pest management programs, but limited information on field efficacy is available. Efficacy, based pheromone trapping data, consists initial reduction in captures after treatment and rebound trap over time. Pattern Tribolium castaneum (Herbst) was evaluated 21 two flour mills. Rebound mean number beetles captured the probability capturing one or more evaluated. threshold beetle capture...
Abstract BACKGROUND Plant bugs ( Lygus spp.) and thrips Thrips are two of the most economically important insect pest groups impacting cotton production in USA today, but not controlled by current transgenic varieties. Thus, seed or foliar‐applied chemical insecticides typically required to protect from these groups. Currently, pests resistant several insecticides, resulting fewer options for viable management. Previous publications documented efficacy event MON 88702 against plant limited...
Abstract The objectives of this study were to quantify the virulence four entomopathogenic fungal species pupae Rhagoletis pomonella (Walsh) (Diptera: Tephritidae) and determine potential combine fungi (EPFs) nematodes (EPNs) for biological control pest. EPFs included Beauveria bassiana (strain GHA), Metarhizium brunneum F52), Isaria javanica (wf GA17), fumosorosea (Apopka 97 strain). In laboratory assays, all reduced adult emergence but there no differences between species. M. examined...
A new strain of Cordyceps javanica (wf GA17) was observed causing widespread epizootics among whiteflies in Southern Georgia 2017. The tolerance conidia to environmental factors including variable temperature and ultraviolet (UV) light compared between this three commercial strains entomopathogenic fungi (Metarhizium brunneum F52, fumosorosea Apopka97, Beauveria bassiana GHA). Under 10–30 °C, C. wf GA17 responded similarly other fungi, with the highest virulence against Galleria mellonella...
Two field strains of the Indianmeal moth, Plodia interpunctella (Hübner); red flour beetle, Tribolium castaneum (Herbst); and lesser grain borer, Rhyzopertha dominica (F.), one strain rusty Cryptolestes ferrugineus (Stephens), were collected from hard winter wheat stored on farms in northeastern Kansas. Fifty eggs P. 25 beetle adults each species exposed to 100 g untreated or treated with various rates spinosad, determine susceptibility corresponding insecticide-susceptible laboratory...
The distribution of phytophagous stink bugs and associated boll injury in margins cotton fields bordering various agronomic crops woodlands were studied 2007 2008. Two commercial fields, ranging size from 7.8 to 12.1 ha Barnwell Lee Counties, SC, sampled weekly each year along predetermined transects at 0, 5, 10, 25 m the outside margin into field. Stink using a ground cloth (0.91 by 0.91 m), quarter-sized bolls (≍2.5 cm diameter) collected examined for internal damage. Density (bugs/row-m)...
Grid sampling (one sample per 0.40 ha) in 12 cotton (Gossypium hirsutum L.) fields for stink bugs and boll injury caused by bug feeding was conducted 2007 2008 South Carolina Georgia. The main species collected using the beat cloth method were green bug, Acrosternum hilare (Say) (69%); brown Euschistus servus (18%); southern Nezara viridula (L.) (14%), respectively. inverted distance weighted interpolation Spatial Analysis Distance IndicEs analyses showed spatial variability both densities....
Megacopta cribraria (F) (Hemiptera: Heteroptera: Plataspidae) was first discovered in North America 9 counties northeastern Georgia (USA) October 2009. By the end of 2012, surveys conducted and neighboring states confirmed that insect had spread into 383 additional southeastern U.S., including Alabama, Florida, Georgia, Mississippi, Carolina, South Tennessee Virginia. It reported from 33 species plants representing 15 taxonomic families these surveys, with 17 those family Fabaceae (legumes)....
