The genome of pineapple mealybug wilt-associated closterovirus-2 (PMWaV-2) was cloned from double-stranded RNA isolated from diseased pineapple and its sequence determined. The 3'-terminal 14861 nt of the single-stranded RNA genome contains ten open reading frames (ORFs) which, from 5' to 3', potentially encode a >204 kDa polyprotein containing papain-like protease, methyltransferase and helica...

Background The state of Espirito Santo has in the fruit growing, one of its main economical activities. One of them, the pineapple growth, represents a good economic potential to increase income and job opportunities in the state. However, diseases such as fusariosis and mealybug wilt of pineapple are responsible for the yield losses of up to 80% [1]. The mealybug wilt of pineapple is caused by...

Adviser: Brigitte Tenhumberg Food acquisition is a complicated task. The profitability of potential food items depends on numerous factors, including the spatial distribution, probability of detection and capture, and suitability of the food. Animals faced with such challenges can use relatively simple mechanisms to maximize foraging efficiency. However, mechanisms that maximize foraging effici...

Ladybird beetles are high-mobility insects and explore broad areas by switching between walking and flying. Their excellent wing transformation systems enabling this lifestyle are expected to provide large potential for engineering applications. However, the mechanism behind the folding of their hindwings remains unclear. The reason is that ladybird beetles close the elytra ahead of wing foldin...

The mealybug chromosome cycle is one of the most dramatic examples of genomic imprinting known. In embryos that are to become male the entire paternal chromosome set becomes heterochromatic and inactive at the blastoderm stage, while the maternal set remains active and euchromatic. HP1 is a protein from Drosophila melanogaster, which binds preferentially to heterochromatin on polytene chromosom...

Recent research has suggested that increasing neighbourhood tree species diversity may mitigate the impact of pests or pathogens by supporting the activities of their natural enemies and/or reducing the density of available hosts. In this study, we attempted to assess these mechanisms in a multitrophic study system of young oak (Quercus), oak powdery mildew (PM, caused by Erysiphe spp.) and a m...

Con este análisis de la película Ladybird, ladybird, del director británico Ken Loach, se busca rendir un homenaje a extensa y reconocida trayectoria académica profesor Javier Lucas Martín, entre cuyas líneas investigación docencia encuentra “Cine Derecho”. En artículo abordan muchas las cuestiones que son objeto estudio tanto en su búsqueda por ampliar profundizar el crítico derecho mundo glob...

Mealybug wilt of pineapple (MWP) is a devastating disease found in all the major pineapple growing regions of the world (4– 6,26). The disease is characterized by severe tip dieback, downward curving of the leaf margins, reddening, and wilting of the leaves that can cause total collapse of the plant. The etiology of MWP has long been in question. The disorder is generally associated with the pr...

Abstract Anagyrus lopezi is a specialist parasitoid was introduced to Indonesia in 2014 control cassava mealybug, Phenacoccus manihoti. Plesiochrysa ramburi and Cryptolaemus montrouzieri are generalist predator insects associated with the mealybug. Intraguild predation crucial competition an insect community. The study objective investigate interference of both predators on healthy mealybug (un...
