Closterovirus Infection and Mealybug Exposure Are Necessary for the Development of Mealybug Wilt of Pineapple Disease [PDF]

Phytopathology®, 2002
The roles of Pineapple mealybug wilt-associated viruses (PMWaVs) and mealybug (Dysmicoccus spp.) feeding in the etiology of mealybug wilt of pineapple (MWP) were evaluated. Container-grown pineapple (Ananas comosus) plants from five commercially grown Hawaiian proprietary selections and a field study utilizing a randomized complete block design were ...

Building capacity in vector‐borne plant virus research: The CONNECTED Network

PLANTS, PEOPLE, PLANET, EarlyView.
Plant viruses spread by insects decimate crop yields globally, causing food security challenges in vulnerable areas, including regions of Africa. Interdisciplinary research is needed to protect future crop supplies. CONNECTED, the Community Network for African Vector‐Borne Plant Viruses, increased research capacity in Central, East, West and Southern ...

First incursion of the Asian root mealybug Ripersiella planetica in Europe (Hemiptera, Coccoidea, Rhizoecidae) [PDF]

, 2012
The Rhizoecidae is a family of the Coccoidea (hodGSon, 2012) containing 233 species worldwide that are hypogaeic and parasitic on plant roots, hence their common name ‘root mealybugs’ (Kozár & Konczné BEnEdicty, 2007).

Drought stress modulates indirect defense via bottom‐up effects in tomato and wheat

Pest Management Science, EarlyView.
Different water regimes can have a significant impact on plant morphology and defense pathways in tomato and wheat, triggering multiple olfactory choices in biocontrol agents of key insect pests. These findings could be used to implement biocontrol strategies within the IPM context under a changing climate scenario.

A preventive strategy for the control of aphids in sweet pepper using lacewings and micrococcinelid beetles

Insect Science, EarlyView.
Aphids pose a serious risk to horticultural crops. Current biocontrol strategies often fail due to the poor establishment of natural enemies when aphids are scarce. We evaluated the potential of two aphidophagous predators, Micromus variegatus and Scymnus interruptus, to be used as preventive biocontrol agents, released before aphid infestation.

Hemipteran vectors of stylet‐borne plant viruses: Aphids lead the charge

Insect Science, EarlyView.
Among all sap‐feeding hemipterans, aphids stand out by far as the most important vectors of noncirculative plant viruses. Compared to whiteflies and mealybugs, aphids’ highly specialized stylet anatomy and distinct feeding behaviors contribute, together with other features of their biology, to their remarkable efficiency in transmitting stylet‐borne ...

Cassava-Mealybug interactions

, 2006
Most basic information on plant-mealybug interactions during the last decade has come from research on the cassava Manihot esculenta Crantz (Euphorbiaceae) system with two mealybug species, namely Phenacoccus manihoti Matile-Ferrero and Phenacoccus herreni Cox and Williams (Sternorrhyncha: Pseudococcidae).
