Host-Plant Variations Affect the Biotic Potential, Survival, and Population Projection of Myzus persicae (Hemiptera: Aphididae)

open access: yesInsects, 2021
The green peach aphid, Myzus persicae Sulzer (Hemiptera: Aphididae), a polyphagous insect pest is a major threat to a wide range of crops worldwide. Aiming to evaluate the life history traits of M. persicae, feeding on different host plants, we used five

Biocontrol against cabbage aphid Brevicoryne brassicae L.

open access: yesIOSR Journal of Environmental Science, Toxicology and Food Technology, 2016
The effects of the aphid parasitoid Diaeretiella rapae (M'Intosh), the predator Coccinella undecimpunctata L. and the entomopathogenic fungus Beauveria bassiana (Bals.) on the cabbage aphid Brevicoryne brassicae L. were evaluated in this study. The effects of host densities on D. rapae parasitizing B.

Do aphid endosymbiotic bacteria influence parasitoid searching behaviour through changes in aphid honeydew production?

open access: yesEcological Entomology, EarlyView.
Hamiltonella defensa infection increases honeydew production in certain aphid genotypes, potentially modifying aphid feeding behaviour. Parasitoid wasps, Aphidius ervi, are more attracted to honeydew from H. defensa‐infected aphids; though larger honeydew amounts may slightly deter searching.

Herbivore induction of the glucosinolate-myrosinase defense system: major trends, biochemical bases and ecological significance [PDF]

open access: yes, 2009
Like many other plant defense compounds, glucosinolates are present constitutively in plant tissues, but are also induced to higher levels by herbivore attack.

Digestive amylolytic and proteolytic activities of Brevicoryne brassicae (Hem.: Aphididae) on different canola cultivars [PDF]

open access: yesنامه انجمن حشره‌شناسی ایران, 2019
Brevicoryne brassicae (L.) is one of the most damaging pests of canola in Iran. Digestive amylolytic and proteolytic activities of adult aphids were evaluated on eight canola cultivars (Opera, SLM046, RGS000, Okapi, Delgan, Licord, H19, and Modena) using

Evaluating Syrphid Fly Predation on Aphids Under Controlled and Field Conditions in High Tunnels: A Comparative Study With Lacewings

open access: yesJournal of Applied Entomology, EarlyView.
ABSTRACT Biological control in high tunnel systems can be optimised by matching predator species to seasonal environmental conditions. We evaluated the predatory efficacy of syrphid flies (Toxomerus marginatus (Say), Eupeodes americanus (Fabricius)) and lacewings (Chrysoperla carnea (Stephens), Chrysoperla rufilabris (Burmeister)) across laboratory ...

Prevention and control of weeds, pests and diseases [PDF]

open access: yes, 2009
Weed control still requires major investments of money and labour in organic arable farming and field vegetable cultivation. For this reason, current research is focused to a large extent on the development of weed control strategies.

Studying, the Insecticidal Effects of Melia azedarach and Citrus limonum Extracts on Two Aphid Species

open access: yesMajallah-i ḥifāẓat-i giyāhān, 2018
Introduction: Wheat (Triticum aestivum L.) is the most principal plant food for 35 percent of the world's population, and canola (Brassica napus L.) is one of the most important brassicaceous crops that play a major role in the development of edible oil.

Evaluation of Cabbage Varieties for Resistance to the Cabbage Aphid

open access: yesAfrican Entomology, 2009
Resistance of nine cabbage (Brassica oleracea van capitata) cultivars, Big cropper, Cape Spitz, Copenhagen Market, Conquistador, Drumhead, Giant Drumhead, Glory of Enkhuizen, Grandslam and Hercules to cabbage aphid (Brevicoryne brassicae) was studied in greenhouse experiments conducted at the Botswana College of Agriculture, Gaborone, Botswana.

Effect of Endophytic Fungi on Thrips tabaci Development and Population Dynamics

open access: yesJournal of Applied Entomology, EarlyView.
ABSTRACT Endophytic fungi are promising biocontrol agents because they colonise healthy plant tissues asymptomatically while inducing systemic resistance that negatively affects herbivorous insects. We investigated whether treatments with the endophytes Trichoderma harzianum and Beauveria bassiana in two onion cultivars (Allium cepa L.; Sturon and Red ...
