Ovicidal and Insecticidal Activities of Pyriproxyfen Derivatives with an Oxime Ester Group

open access: yesMolecules, 2017
Based on the structural framework of a pyriproxyfen metabolite, nineteen oxime ester derivatives were synthesized via reaction of the carboxylic acids with 4-(2-(2-pyridinyloxy)ethoxy)benzaldehyde oxime.

Host plant influence on different subspecies of Myzus persicae (Sulzer) and de generalist aphid parasitoid Praon volucre (Hallday) [PDF]

open access: yes, 2005
15 p.The green peach aphid Myzus persicae (Sulzer) is a polyphagous pest with different host ranges. Myzus persicae sensu stricto is a very polyphagous aphid, while Myzus persicae nicotianae is a subspecies more specialised on tobacco.

The effects of six species of aphids on some life history parameters of the ladybird Propylea quatuordecimpunctata (Coleoptera: Coccinellidae)

open access: yesEuropean Journal of Entomology, 2005
One of the factors affecting the effectiveness of predatory coccinellids in an aphid infested crop is the food specificity of the predator. The response towards six species of aphids (Sternorrhyncha: Aphididae) was therefore tested in one of the most ...

Evaluation of Insecticides induced hormesis on the demographic parameters of Myzus persicae and expression changes of metabolic resistance detoxification genes

open access: yesScientific Reports, 2018
Insecticide induced-hormesis is a bi-phasic phenomenon generally characterized by low-dose induction and high-dose inhibition. It has been linked to insect pest outbreaks and insecticide resistance, which have importance in the integrated pest management

Associational resistance or susceptibility:the indirect interaction between chemically-defended and non-defended herbivore prey via a shared predator [PDF]

open access: yes, 2016
Many organisms possess chemical defences against their natural enemies, which render them unpalatable or toxic when attacked or consumed. These chemically-defended organisms commonly occur in communities with non- or less-defended prey, leading to ...

Changes in the free amino acid composition of Capsicum annuum (pepper) leaves in response to Myzus persicae (green peach aphid) infestation. A comparison with water stress

open access: yesPLoS ONE, 2018
Amino acids play a central role in aphid-plant interactions. They are essential components of plant primary metabolism, function as precursors for the synthesis of defense-related specialized metabolites, and are major growth-limiting nutrients for ...

Multitrophic interactions in a potato-aphid system

open access: yes, 2011
In interactions between plants, insect herbivores and natural enemies, resistant plant varieties and soil abiotic/biotic factors can affect natural enemies through changes in the plant or host insect.

Effect of Temperature on the Biology and Predatory Potential, of Harmonia Dimidiata (Fab.) (Coleoptera: Coccinellidae) Feeding on Myzus Persicae (Sulzer) (Hemiptera: Aphididae) Aphid [PDF]

open access: yes, 2016
The influence of five constant temperatures i.e 16±1°C, 20±1°C, 24±1°C, 28 ±1°C and 32 ±1 ˚C was investigated on the biology and predatory potential of Coccinellid beetle, Harmonia dimidiata (Fab.), (Coccinellidae: Coleoptera), feeding on Myzus persicae
