Toxins for Transgenic Resistance to Hemipteran Pests [PDF]
, 2012 The sap sucking insects (Hemiptera), which include aphids, whiteflies, plant bugs and stink bugs, have emerged as major agricultural pests. The Hemiptera cause direct damage by feeding on crops, and in some cases indirect damage by transmission of plant ...

Effect of Endophytic Fungi on Thrips tabaci Development and Population Dynamics
Journal 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 ...

Aphids associated with shrubs, herbaceous plants and crops in the Maltese Archipelago (Hemiptera, Aphidoidea) [PDF]
, 2011 A survey of the aphids associated with Maltese shrubs, herbaceous plants and crops was carried out. Sixty six aphid species were recorded from more than 90 species of host plants.

Why is there no impact of the host species on the cold tolerance of a generalist parasitoid? [PDF]
, 2017 For generalist parasitoids such as those belonging to the Genus Aphidius, the choice of host species can have profound implications for the emerging parasitoid. Host species is known to affect a variety of life history traits.

Plant Biotechnology Journal, EarlyView.ABSTRACT Candidatus Liberibacter asiaticus (CLas), the causative agent of citrus Huanglongbing (HLB), is transmitted by Asian citrus psyllid, Diaphorina citri; however, the role of the insect's immune effectors in defending against CLas remains poorly understood. This study reveals that D.

Gene knockdown by RNAi in the pea aphid Acyrthosiphon pisum [PDF]
BMC Biotechnology, 2007 RNA interference (RNAi) is a powerful method to inhibit gene expression in a sequence specific manner.Here, we described the development of RNAi by micro-injection of double-stranded RNA (dsRNA) in the pea aphid Acyrthosiphon pisum. Injection of dsRNA into whole aphid body induced the silencing of two marker genes with different expression patterns ...

Three Decades of China's Bt Cotton: Achievements and Insights
Plant Biotechnology Journal, EarlyView.ABSTRACT Cotton is a vital natural fibre crop with significant economic value worldwide. In response to the threat of cotton bollworm (Helicoverpa armigera), the China government initiated a research project in 1992 to develop transgenic Bacillus thuringiensis (Bt) cotton.

Expansion of the miRNA Pathway in the Hemipteran Insect Acyrthosiphon pisum [PDF]
Molecular Biology and Evolution, 2010 The pathways that allow short noncoding RNAs such as the microRNAs (miRNAs) to mediate gene regulation and control critical cellular and developmental processes involve a limited number of key protein components. These proteins are the Dicer-like RNases, double-stranded RNA (dsRNA)-binding proteins, and the Argonaute (AGO) proteins that process stem ...
