Combined effects of the landscape and crop management on ant communities
At small spatial scales, agricultural management acts as a stronger ecological filter than landscape context, significantly shaping ant community composition. Species richness and frequency did not differ among treatments, indicating the predominance of generalist species.

ABSTRACT Huanglongbing (HLB) is the most destructive citrus disease worldwide, and it has been disseminated by the Asian citrus psyllid Diaphorina citri, the vector of the causing agent Candidatus Liberibacter asiaticus. Although processed kaolin reduces psyllid infestation, long‐term field data from commercial orchards are limited.

ABSTRACT Globally, citrus production areas are threatened by greening diseases, also known as Huánglóngbíng (HLB), associated with phloem‐limited gram‐negative species of the genus Candidatus Liberibacter. Those pathogens are transmitted by either the Asian citrus psyllid, Diaphorina citri Kuwayama 1908 (Hemiptera: Psyllidae), or the African citrus ...

Using DNA barcoding for identification of some psyllids (Hemiptera: Psylloidea) intercepted at South Korea ports-of-entry [PDF]
Quick and accurate identification of intercepted psyllids (Hemiptera: Psylloidea) is an essential requirement for effective pest management and phytosanitary procedures.

ABSTRACT Methyl salicylate (MeSA) is an herbivore‐induced plant volatile (HIPV) known to attract natural enemies of herbivores; however, its effectiveness as a semiochemical across diverse cropping systems and broad geographic regions remains unclear. In this 2‐year field study, we sampled natural enemies using MeSA‐baited and unbaited (control) yellow

ABSTRACT Wheat stem sawfly, Cephus cinctus Norton (Hymenoptera: Cephidae), is a long‐standing and serious pest of wheat, Triticum aestivum Linnaeus (Poaceae), in the northern Great Plains region of North America. Over the last decade, research efforts have aimed to better understand C.

Percentage of C1 psyllids with detectable levels of CLs.
*Transmission studies were performed with the low-CLs psyllid colony. A conventional and nested PCR was used to assess CLs percentage in sampled population at 5 and 12 weeks of plant exposure to psyllids.
