Temperature dependent functional response of Diaeretiella rapae (Hymenoptera: Aphidiidae) to the cabbage aphid, Brevicoryne brassicae (Hemiptera: Aphididae)

open access: yesEuropean Journal of Entomology, 2013
Diaeretiella rapae MacIntosh (Hymenoptera: Aphidiidae) is one of the most common and successful parasitoids of the cabbage aphid. The functional response of D. rapae towards cabbage aphids was examined in laboratory studies at three constant temperatures,

Bifenthrin resistance in Dalbulus maidis (Hemiptera: Cicadellidae): inheritance, cross‐resistance, and stability

open access: yesPest Management Science, EarlyView.
Resistance of Dalbulus maidis to bifenthrin was autosomal, incompletely dominant, and polygenic. Additionally, this resistance was unstable in the absence of selection pressure. Abstract BACKGROUND Pyrethroid insecticides have been a primary strategy for managing Dalbulus maidis (Hemiptera: Cicadellidae) in Brazil. Howeve, failures in the control of D.

Temporal variations in the life-cycles of aphids (Sternorrhyncha: Aphididae) and their coccinellid predators

open access: yesEuropean Journal of Entomology, 2015
Aphids are either monoecious living either on trees or herbaceous plants, or heteroecious, which involves host alternating between a tree (primary host) and a herbaceous plant (secondary host).

Life history and fitness costs in the lambda‐cyhalothrin resistant clone of English grain aphid, Sitobion avenae (Fabricius)

open access: yesPest Management Science, EarlyView.
The purpose of this study is to investigate the life‐history traits and fitness costs of English grain aphid clones that are resistant to lambda‐cyhalothrin (SA3) and susceptible to it (SA27). Overall, the results showed that there are differences in the stages of development, survival, reproduction and population growth.

Functional responses and intraspecific competition in the ladybird Harmonia axyridis (Coleoptera: Coccinellidae) provided with Melanaphis sacchari (Homoptera: Aphididae) as prey

open access: yesEuropean Journal of Entomology, 2018
Functional responses at each developmental stage of predators and intraspecific competition associated with direct interactions among them provide insights into developing biological control strategies for pests.

Using fecal DNA metabarcoding to investigate the animal diet of black rails, yellow rails, and soras

open access: yesWildlife Society Bulletin, EarlyView.
We used fecal DNA metabarcoding to investigate the diet of yellow rails, Eastern black rails, and sora during the non‐breeding season. Arthropods, particularly ants, were prevalent in their diets, suggesting possible interactions with invasive red imported fire ants.

Effects of diet on development and reproductive fitness of two predatory coccinellids (Coleoptera: Coccinellidae)

open access: yesEuropean Journal of Entomology, 2015
Studies of prey suitability are needed to develop efficient mass rearing programs for generalist predators and to understand their potential contribution to integrated pest management.

Flight activity of aphids as potential vectors of viral infection of alfalfa in Serbia [PDF]

open access: yesPesticidi i Fitomedicina, 2017
Flight activity of aphids as potential vectors of viral infection of alfalfa plants were monitored in Serbia for the first time in Europe. Research was conducted at the location Progar (Srem) for two years using six yellow water traps.
