Simultaneous Parasitism of Field-Collected Green Cloverworm, \u3ci\u3eHypena Scabra\u3c/i\u3e (Lepidoptera: Noctuidae) Larvae by Endoparasitioids and an Entomopathogenic Fungus [PDF]

, 2018
The impacts of entomopathogens (e.g., fungi, bacteria, protists and viruses) on larval Lepidoptera and their associated insect parasitoids have been examined in laboratory studies but field studies of interaction between these two mortality factors are ...

Effects of bioinsecticide exposure route on aphids and their natural enemies in oilseed rape

Pest Management Science, EarlyView.
Fatty acids, silicone polymers and surfactants reduced aphid numbers but caused natural enemy mortality under direct exposure, while minimal residual activity suggests potential for targeted, compatible use in integrated pest management. Abstract BACKGROUND Myzus persicae Sulzer and Brevicoryne brassicae L.

Reversed impacts by specialist parasitoids and generalist predators may explain a phase lag in moth cycles : a novel hypothesis and preliminary field tests [PDF]

, 2013
Among cyclic populations of herbivores, inter-specific temporal synchrony has been attributed to both climatic factors and trophic interactions. In northern Europe, winter and autumnal moths undergo regular 9–11 year population cycles.

Potential of Beauveria bassiana in the control of Euschistus crenator (Hemiptera: Pentatomidae) and selectivity to the parasitoid Telenomus podisi (Hymenoptera: Scelionidae)

Pest Management Science, EarlyView.
Entomopathogenic fungi effectively suppressed the emerging soybean pest Euschistus crenator, with isolates LCMAP106, UFSM‐01 and a commercial bioinsecticide achieving the highest mortality. These agents did not reduce parasitism or survival of the egg parasitoid Telenomus podisi, highlighting their potential for integration into environmentally ...

A comparative study of the function of heterospecific vocal mimicry in European passerines [PDF]

, 2007
Although heterospecific vocal imitation is well documented in passerines, the evolutionary correlates of this phenomenon are poorly known. Here, we studied interspecific variation in vocal mimicry in a comparative study of 241 European songbirds.

Control failure risk, resistance and enzymatic activity of neurotoxic insecticides in Brazilian populations of Leucoptera coffeella (Lepidoptera: Lyonetiidae)

Pest Management Science, EarlyView.
Bioassays of 36 Leucoptera coffeella populations revealed resistance to neurotoxic insecticides, control failures of ≤62.9% and enzyme activity variation, with particularly high GST and low AChE levels. Abstract Background Leucoptera coffeella is a key pest of coffee crops in Brazil, causing significant damage by mining coffee leaves.

Detection of Toxoplasma gondii DNA by polymerase chain reaction in experimentally desiccated tissues

Memorias do Instituto Oswaldo Cruz, 2004
Despite toxoplasmosis being a common infection among human and other warm-blooded animals worldwide, there are no findings about Toxoplasma gondii evolutionary forms in ancient populations.

Assessing pest control treatments from phenology models and field data

Pest Management Science, Volume 81, Issue 4, Page 1851-1859, April 2025.
Theoretical effect of two larvicide sprays, two delayed larvicide sprays that follow an oil treatment, mating disruption, and mating disruption plus four virus sprays on codling moth larva (brown for treated versus pink for untreated) and adult (dark green for treated versus light green for untreated) phenology.

Influence of egg card color preference, inoculation time, generational succession, and learning experience on the parasitism of Trichogramma ostriniae.

PLoS ONE
This study investigated the parasitic selection preferences of female Trichogramma ostriniae on egg cards of different colors, considering the effects of inoculation time, generations, and learning experiences on wasp parasitism.
