High-Throughput Sequencing Reveals New Viroid Species in in Mexico.

In the main cactus pear ()-producing region in the State of Mexico, fruit production occupies the largest cultivated area with 15,800 ha, while 900 ha are cultivated for edible young pads ("nopalitos") which are consumed as vegetables. Two composite samples consisting of cladodes of plants for fruit production ( = 6) and another of "nopalitos" ( = 6) showing virus-like symptoms were collected. Both sample sets were subjected to high-throughput sequencing (HTS) to identify the viruses and viroids.

Interactions of with and (Hemiptera: Dactylopiidae) through the Study of Their Volatile Compounds.

has always interacted with many phytophagous insects; two of them are and . Fine cochineal () is produced to extract carminic acid, and , or wild cochineal, is an invasive pest of in more than 20 countries around the world. Despite the economic and environmental relevance of this cactus, , and , there are few studies that have explored volatile organic compounds (VOCs) derived from the plant-insect interaction.

Combined application of entomopathogenic fungi and predatory mites for biological control of Tetranychus urticae on chrysanthemum.

Background: Most studies on efficacy of fungal pathogens and predatory mites against Tetranychus urticae have been done on individual species in the laboratory. We evaluated fungi and predatory mites separately and together against glasshouse populations of T. urticae on chrysanthemum plants.

Effect of Pepper Variety on the Susceptibility of Pepper Weevil Parasitoids.

Anthonomus eugenii Cano (Coleoptera: Curculionidae) is a key pest of cultivated peppers (Capsicum species) in tropical and subtropical America. Here we evaluated the effect of five pepper varieties on the susceptibility of A. eugenii to the parasitoids Bracon sp.

Toxicity and Residual Activity of Insecticides against , a Parasitoid of the Diamondback Moth.

is the main pest of cruciferous crops worldwide. To reduce populations, better integration of natural control and chemical control (dominant tactic used) is needed. This work analyzed the compatibility of nine insecticides with the parasitoid , outlining them as complementary tools in an integrated pest management strategy.
