Summary Lifetime patterns of carbohydrate and lipid metabolism were compared in starved sucrose‐fed adults the parasitoid Macrocentrus grandii (Goidanich) (Hymenoptera: Braconidae). As expected, individuals lived longer than did individuals. males females eclosed with levels simple storage sugars (presumably primarily trehalose) glycogen that below maximum recorded from parasitoids. Both these nutrients dropped to very low within 4 days post‐emergence maintained at high throughout their...
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
Abstract Gossypol is an important allelochemical produced by the subepidermal glands of some cotton varieties and for their ability to respond changing biotic stress exhibiting antibiosis against pests. Plant growth‐promoting rhizobacteria (PGPR) are root‐colonizing bacteria that increase plant growth often elicit defence pathogens insect Little known about effect PGPR on plant–insect interactions potential biochemical molecular mechanisms which enhance defence. Here, we report ( Bacillus...
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.
Plant growth-promoting rhizobacteria (PGPR) enhance plant growth under the influence of multigenic processes, including nitrate (NO3−) and ammonium (NH4+) uptake genes, which could potentially explain improvement in nutrition promotion. Studies on effects PGPR inoculation regulation NO3− NH4+ genes nutrient accumulation using soil or soil-like substrates are limited. Here, we tested hypothesis that application Bacillus mixtures increases overall growth, transcript levels Arabidopsis...
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 Aprostocetus hagenowii (Ratzburg) is a generalist parasitoid of cockroach (Blattodea) oothecae. Previous studies examining the host range A. have largely focused on cockroaches economic and medical importance, which represent minority species in an order filled with diverse morphology, behavior, ecology. The aim this study was to expand known emphasis nonpest as well pest from 3 families (Blattidae, Corydiidae, Ectobiidae). Previously recorded were also reexamined. Oothecae 17...
Abstract The reproductive fitness of parasitoids is dependent on their ability to find optimal hosts for oviposition and nectar/honeydew as a sugar source survival reproduction. Learning ecologically relevant odors helps refine foraging behavior enhance success. However, little known about how associative learning may help optimize flight while food and/or hosts. This study compared the inflight behavioral responses naïve experienced Microplitis croceipes (Cresson) (Hymenoptera: Braconidae)...
We compared the lifespan of Macrocentrus grandii (Goidanich) adults fed a 50% sucrose solution at various intervals throughout their lives. Treatments included starvation, continuous feeding, feeding on first day life only, and every second, third, or fourth life. Life expectancy for starved males females was less than 3 d, providing sugar during increased by 2 d 4 females. highest when were continuously (14 21 females) (17 23 females). The that either ranged between 9 16 d. Together, these...
The fumigant toxicity of eight essential oil components, 1-8-cineole, carvacrol, eugenol, (−)-menthone, (−)-linalool, S-(−)-limonene, (−)- β -pinene, and (+)- α was tested against the cowpea weevil, Callosobruchus maculatus (Fabricius) (Coleoptera: Chrysomelidae), at 0.25–60 µ L/L air doses. 1-8-Cineole, eugenol caused complete adult mortality 10 24 h after treatment. 1-8-Cineole carvacrol were most toxic with LD 50 values 0.24 0.6 h, respectively. -Pinene -pinene least 31 31.4 Toxicity...
Plant induced defense against herbivory are generally associated with metabolic costs that result in the allocation of photosynthates from growth and reproduction to synthesis compounds. Therefore, it is essential plants capable sensing differentiating mechanical injury herbivore injury. Studies have shown oral secretions (OS) caterpillars contain elicitors plant responses. However, studies shows whether these originated salivary glands or other organs feeding, such as ventral eversible...
Abstract The endoparasitic wasps (Hymenoptera: Braconidae), Microplitis croceipes (specialist), and Cotesia marginiventris (generalist) are parasitoids of lepidopteran larvae that differ in their degree host specificity. Previous studies by our group have reported key differences the response both to host‐related volatiles. To possibly understand basis for results, we compared abundance antennal sensilla sexes parasitoid species using scanning electron microscopy silver‐staining techniques....
Abstract Larvae of Ostrinia nubilalis (Hübner) cause significant damage to maize ears and reduce market value fresh sweet corn. Females rely on volatile cues locate oviposit preferentially plants. In addition, oviposition behavior females is influenced by soil management practices as they usually lay more eggs plants grown conventional than organic soils that harbor rich microbial diversity. Since some plant growth‐promoting rhizobacteria (PGPR) are known mediate health via suppression...
Halyomorpha halys is an invasive, widespread stink bug for which only short-term solutions are currently available pest control worldwide. The need long-term management H. has driven studies on augmentative and classical biological of this species, especially by its egg parasitoids. Numerous investigations in Asia, USA, Europe native exotic parasitoids , the effects non-target pentatomids, have improved global knowledge parasitoid-host relationships, uncovered new associations, led to...
