We outline the diversity of pests, weeds and plant pathogens absent from New Zealand that threaten forage production, examine their potential import pathways, and outline the challenges of managing them should they arrive. The number and diversity of threats and pathways indicates ongoing incursions are inevitable.

Read the free Plain Language Summary for this article on the Journal blog. Abstract Herbivory can affect the soil microbiome, creating legacies that affect plant resistance, but how these effects vary by feeding guild and the plant traits involved remain underexplored. We tested how soil legacies created by a leaf‐chewing caterpillar (Spodoptera exigua)

The chemical ecology of armyworms [PDF]
Moths of the genus Spodoptera are economically important pest insects. The necessity to develop novel control strategies which may be included in integrated pest management schemes has led to the study of chemical communication in several species within ...

Adult Beet Armyworm and Fall Armyworm: Histology of the Compound Eyes
The compound eyes of the beet armyworm, Spodoptera exigua (Hubner), and the fall armyworm, S. frugiperda (J. E. Smith), are composed, respectively, of 6-7 thousand ommatidia 240-290 @mm long and 10-12 thousand ommatidia 400-470 @mm long. Both species have lenses ca. 18 @mm wide and 8 @mm thick.

Accurate and efficient identification of jute pests is essential to sustaining agricultural yield and preventing fiber‐quality degradation in jute (Corchorus spp.) production. Traditional visual inspection is subjective, labor‐intensive, and error‐prone under variable field conditions, motivating the need for robust automated classification systems ...

Comparative life table parameters of beet armyworm, Spodoptera exigua (Lep.: Noctuidae), on four commercial sugar beet cultivars [PDF]
Life table parameters of the beet armyworm, Spodoptera exigua (Hübner), on four sugar beet cultivars (Renger, FD0005, Dorothea and Shirin) were studied in laboratory at 27 ± 1°C, 60 ± 5% RH and a photoperiod of 16L: 8D hours.

Cowpea volatiles induced by beet armyworm or fall armyworm differentially prime maize plants
Exposure to herbivore-induced plant volatiles (HIPVs) is known to enhance the defense responses in plants. This so-called priming effect has only been marginally studied in intercropping systems. We tested whether HIPVs from cowpea, which often serves as an intercrop alongside maize, can prime herbivore-induced volatile emissions in maize. Conventional

Plant–herbivore interactions depend on plant richness, plant and soil history
Read the free Plain Language Summary for this article on the Journal blog. Abstract Insect herbivores play a central role in grassland ecosystems. They depend on plants for their nutrition and exert feedback effects on plant communities. Although such reciprocal relationships are well recognized, how they are shaped by plant community diversity and ...

Effect of foliar spray of elicitors on status of defense proteins in relation to mustard aphid infestation in crop Brassica cultivars [PDF]
Mustard aphid, Lipaphis erysimi Kalt., is the key insect pest of crop Brassicas causing significant reduction in crop yield. In the present study, widely grown Brassica cultivars RLC-1 (Brassica juncea) and GSC-6 (Brassica napus) were treated with ...

ABSTRACT Entomopathogenic nematodes (EPNs) are key biological control agents in agriculture, but their direct effects on plant metabolism and resistance to herbivory remain underexplored. By combining transcriptomic, metabolomic, and herbivore assays, this study aimed at providing a holistic description of maize root responses to EPNs and to assess ...
