Assessing the host plants of the invasive apricot aphid, Myzus mumecola (Hemiptera: Aphididae)

Agricultural and Forest Entomology, EarlyView.
We investigated the host plants of the invasive apricot aphid Myzus mumecola (Hemiptera: Aphididae), an emerging pest species in Europe, by combining molecular and ecological approaches. The winter host plant was confirmed as apricot by both methods.

Manipulation of plant defense responses by the tomato psyllid (Bactericerca cockerelli) and its associated endosymbiont Candidatus Liberibacter psyllaurous. [PDF]

PLoS ONE, 2012
Some plant pathogens form obligate relationships with their insect vector and are vertically transmitted via eggs analogous to insect endosymbionts. Whether insect endosymbionts manipulate plant defenses to benefit their insect host remains unclear.

Insects and Survival: A Review of Primary and Secondary Defense Strategies

Entomologia Experimentalis et Applicata, EarlyView.
Based on a review of three decades of literature, insect defense mechanisms are classified into primary (I) and secondary (II) mechanisms of behavioral, morphological, and chemical nature. These mechanisms have been recorded in 22 (I) and 20 (II) orders, respectively.

Unravelling the Molecular Identity of Bulgarian Jumping Plant Lice of the Family Aphalaridae (Hemiptera: Psylloidea)

Insects
Psyllids (Hemiptera: Psylloidea) are plant sap-sucking insects whose identification is often difficult for non-experts. Despite the rapid development of DNA barcoding techniques and their widespread use, only a limited number of sequences of psyllids are

Efficacy of Zeolite and Kaolin in the Control of Cacopsylla pyri (L.) (Hemiptera: Psyllidae) and Compatibility With Its Natural Antagonist Anthocoris nemoralis (Fabricius) (Hemiptera: Anthocoridae)

Journal of Applied Entomology, EarlyView.
ABSTRACT The pear psyllid Cacopsylla pyri is a major pest of European pear orchards, responsible for significant yield losses. Its management is increasingly challenged by restrictions on synthetic active ingredients, resistance development, and the shift towards sustainable production systems.

Psyllid Cysteine Cathepsins Directly Cleave the Outer Membrane Protein BamD of Citrus Huanglongbing Pathogen

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.
