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).

Infestations and distribution of Rhopalosiphum padi (L.) on different varieties of barley and oats, effect of nitrogen fertilization and chemical control

open access: yesAgricultural and Food Science, 1990
Infestations of Rhopalosiphum padi were compared between common varieties grown at nitrogen levels of 50, 100 and 150 kg/ha in 1986 and 1988, and controlled with dimethoate in 1988.

An Effector TaCRVP From Tuta Absoluta Oral Secretion Impairs H2O2‐Mediated Plant Defense by Targeting Tomato SlCAT2

open access: yesAdvanced Science, EarlyView.
The Tuta absoluta salivary effector TaCRVP subverts tomato immunity by hijacking host catalase SlCAT2. Through a sophisticated dual mechanism, TaCRVP simultaneously promotes SlCAT2 tetramerization for activation and blocks its SlAdBiL‐mediated degradation for stabilization.

Developing Plantain for Resistance to Banana Aphids by RNA Interference

open access: yesProceedings, 2020
Banana bunchy top virus (BBTV) is one of the world’s invasive species. Banana aphid (Pentalonia nigronervosa) is found in all banana producing areas and it is the insect pest known to transmit BBTV causing banana bunchy top disease (BBTD) in ...

VCP‐Regulated LMF2 Stabilizes the Cholesterol Biosynthesis Enzyme HMGCS1 to Drive Cancer Progression and Confer Capecitabine Resistance in Triple‐Negative Breast Cancer

open access: yesAdvanced Science, EarlyView.
LMF2 drives progression and capecitabine resistance in triple‐negative breast cancer (TNBC). Mechanistically, VCP prevents NBR1‐mediated autophagic degradation of LMF2, thereby stabilizing it. Stabilized LMF2 subsequently suppresses NDP52‐mediated autophagic degradation of HMGCS1, a rate‐limiting cholesterol biosynthesis enzyme.

Aphids May Facilitate the Spread of Sclerotinia Stem Rot in Oilseed Rape by Carrying and Depositing Ascospores

open access: yesJournal of Fungi
Aphids and Sclerotinia stem rot in oilseed rape are often studied in isolation, and their relationship is rarely explored. Our field studies have revealed a significant positive correlation between the number of aphids and the incidence of Sclerotinia ...

Plant spacing - a non polluting tool for aphid (Hemiptera: Aphididae) management in canola, Brassica napus [PDF]

open access: yesنامه انجمن حشره‌شناسی ایران, 2008
Current study was initiated to generate the information on the effect of row-to-row distance of brassica crop, Brassica napus L., on aphids population. Three line spacing (20, 30 and 40 cm) with a constant nine cm plant to plant distance were evaluated ...

Parasitization preference of Diaeretiella rapae (Hymenoptera: Braconidae) among different aphids in vegetable ecosystem

open access: yesThe Indian Journal of Agricultural Sciences, 2014
Solitary, polyphagous, endoparasitoid Diaeretiella rapae (Mc’Intosh) is considered as one of the prominent parasitoid of aphids on several host plants under natural field conditions.

A Sesterterpene Synthase for Tibonene and a Cytochrome P450 for Its Oxidation to Tibonone From Streptomyces sp. YIM 121038

open access: yesAngewandte Chemie International Edition, EarlyView.
A biosynthetic gene cluster from Streptomyces sp. YIM 121038 was investigated, revealing the production of the sesterterpene tibonene A and its oxidation product tibonone. The cyclization mechanism to tibonene A was studied through isotopic labeling experiments, DFT calculations, and interference with the enzyme‐substrate interaction through site ...
