Does the munch affect the bunch? Using community science to explore insect herbivory and fruit production in an understory plant

Ecological Entomology, EarlyView.
We used iNaturalist records, a longitudinal field survey, and a simulated herbivory experiment to explore how insect herbivory factors are associated with Cornus canadensis fruit production. Naturally observed internal and external insect herbivory was mostly low intensity and did not have a strong relationship with fruit production.

Effects of Invasive Winter Moth Defoliation on Tree Radial Growth in Eastern Massachusetts, USA

Insects, 2014
Winter moth, Operophtera brumata L. (Lepidoptera: Geometridae), has been defoliating hardwood trees in eastern Massachusetts since the 1990s. Native to Europe, winter moth has also been detected in Rhode Island, Connecticut, eastern Long Island (NY), New

Genome assembly of Elcysma westwoodi provides insights into host‐plant cyanogenic glucoside detoxification and chemical defence gene evolution

Insect Molecular Biology, EarlyView.
A chromosome‐level genome of Elcysma westwoodi was assembled. The genome encodes 272 detoxification‐related genes. A single‐copy bCAS was retained for cyanide detoxification. CYP405A and CYP332A were recruited into cyanogenic defence evolution. UGT33A retained a conserved GT‐B fold and catalytic domains.

Influence of meteorological conditions and crown defoliation on tree phenology in intensive forest monitoring plots in Slovenia

Acta Silvae et Ligni, 2014
Data from the forest monitoring programme in Slovenia were used to assess the relationship between tree phenology, crown defoliation and meteorological conditions in Fagus sylvatica, Quercus robur and Picea abies forests in the 2004-2013 period.

First Record of Larval Parasitism in Disonycha glabrata (F.) (Coleoptera: Chrysomelidae) by Myiopharus ancilla (Walker) (Diptera: Tachinidae)

Journal of Applied Entomology, EarlyView.
ABSTRACT The amaranth flea beetle, Disonycha glabrata (F.), is a major pest of amaranth crops (Amaranthus spp.) in the United States. Despite its economic impact, its natural enemy complex remains poorly documented. In this study, we report the first record of larval parasitism in D. glabrata by the tachinid fly Myiopharus ancilla (Walker).

STUDY OF DEFOLIATION INTENSITY AND NITROGEN RATE EFFECTS ON YIELD, YIELD COMPONENTS AND GERMINATION TRAITS OF PRODUCED SEED IN WHEAT (Triticum aestivum)

Agricultura, 2013
A field experiment and a laboratory experiment were conducted in 2011-2012 to determine the effect of defoliation intensity and nitrogen rate on yield, yield components and seed germination of wheat (Triticum aestivum).

Satire and Silence Under Authoritarian Rule: Cotton and Pesticide Perceptions in Tajikistan

Journal of Agrarian Change, EarlyView.
ABSTRACT Over the past 70 years, agricultural chemicals have become a mainstay of cotton farming in Central Asia. This growing reliance on agrochemicals has not remained uncontested. This article analyses the politics of pesticides in Soviet and post‐Soviet Tajikistan by examining how, and to what extent, pesticides have featured in graphic satire, an ...

Functional memory of drought affects leaf chemical defenses and microbial interactions in aspen

New Phytologist, EarlyView.
Experimental design of the common garden study. Summary Drought is an important driver of tree mortality, but its long‐term impacts on trait expression remain poorly understood. Leaves are a key interface at which trees respond to abiotic stress, and foliar traits such as chemical defenses and microbial communities may play a role in determining post ...

Genomic loci associated with leaf abscission contribute to machine picking and environmental adaptability in upland cotton (Gossypium hirsutum L.)

Journal of Advanced Research
Introduction: Defoliation by applying defoliants before machine picking is an important agricultural practice that enhances harvesting efficiency and leads to increased raw cotton purity.
