Abstract:
... We sequenced the complete mitochondrial (mt) genome of brown citrus aphid, Aphis (Toxoptera) citricidus (Kirkaldy) and compared it with that of other aphids. The mt genome of A. citricidus is a circular molecule of 16,763 bp with 84.0% AT content, containing 13 protein-coding genes (PCGs), 2 rRNAs, 22 tRNAs, a control region (CR) and an additional repeat region between trnE and trnF. Like other ap ...

Abstract:
... Food security and biodiversity conservation are threatened by the emergence and spread of pest and pathogens, and thus there is a current need to develop pest management strategies that are sustainable and friendly to the environment and human health. Here, we performed laboratory and field bioassays to evaluate the insecticidal effects of several concentrations of capsaicinoids and glucosinolates ...

Abstract:
... Although species interactions are often proposed to be stronger at lower latitudes and elevations, few studies have evaluated the mechanisms driving such patterns. In this study, we assessed whether, and by which mechanisms, abiotic changes associated with elevation altered the outcome of an ant–aphid protection mutualism. To do so, we characterized the multi‐trophic interactions among the ant For ...

Abstract:
... In 2009, a new citrus viral disease caused by Citrus yellow vein clearing virus (CYVCV) was first discovered in China and now CYVCV is widely distributed in the field. CYVCV is transmissible by grafting and is spread by aphids from lemon to bean, and from bean to bean. However, until now, no vector has been shown to transmit CYVCV from citrus to citrus. In this study, after a 24-h acquisition acce ...

Despite indications that aphids in the same ecological niche show similar levels of facultative symbiont richness, existing reports do not consider the potential role of host plants on aphid microbial community. Little is known a ...

In this study, we evaluated multitrophic drivers of herbivore abundance for an aphid species (Aphis helianthi) in a subalpine food web consisting of a host plant (Ligusticum porteri), mutualist ants and predatory lygus bugs (Lygus spp.). We used a model-selection approach to determine which clim ...

Associations of facultative symbionts and aphids are quite variable in terms of diversity and prevalence across aphid species. Facultative symbionts can have a major impact on aphid bioecological traits. A ...

Abstract:
... An exotic aphid pest (Aphis cytisorum) has infested an invasive plant (Spartium junceum) in the Peruvian Andes since 2005.

We evaluated the infestation of aphids and fungus on S. junceum and on another Andean plant species in 2007 and 2015, measuring the effects of ...
