Demography and Population Projection of Flea Beetle, Agasicles hygrophila (Coleoptera: Chrysomelidae), Fed on Alligator Weed Under Elevated CO2
Abstract The flea beetle, Agasicles hygrophila Selman and Vogt, was introduced into China in 1987. For a more comprehensive understanding of the effect of elevated CO2 concentration on the populationExpand
Sex ratio effects on copulation, fecundity and progeny fitness for Agasicles hygrophila, a biological control agent of alligator weed
TLDR
Females at 20% and 33.3% were found to be optimal for mass rearing of the beetle, and the copulation frequency and duration in males decreased, whereas those in females increased as the number of males increased. Expand
Parasitised caterpillars suffer reduced predation: potential implications for intra-guild predation
TLDR
It is shown that parasitism by the koinobiont wasp Cotesia vestalis is associated with behavioural changes in its larval host (diamondback moth, Plutella xylostella) that reduce risk of IGP, suggesting a trade-off between IGP avoidance and nutrient intake by the host. Expand
Indirect Effect of Elevated CO2 on Population Parameters and Growth of Agasicles hygrophila (Coleoptera: Chrysomelidae), a Biocontrol Agent of Alligatorweed (Amaranthaceae).
Alligatorweed, Alternanthera philoxeroide (Mart.) Griseb. (Amaranthaceae) is an invasive weed in China that is often kept under control by the alligatorweed flea beetle, Agasicles hygrophila SelmanExpand
Water Hyacinth Eichhornia crassipes (Mart.) Solms
Water hyacinth, Eichhornia crassipes, is considered as one of the world’s worst weeds. They successfully invaded lakes, ponds, canals, and rivers. It is still rapidly spreading into manyExpand
Physiological and biochemical responses of Camellia sinensis to stress associated with Empoasca vitis feeding
TLDR
The results indicate that although C. sinensis displays a certain level of tolerance to E. vitis feeding stress, higher density of leafhoppers, and longer exposure duration, can cause severe damage to tea leaves and also a decline in plant defense of tea, so as to affect the tea quality. Expand
Spatio-temporal distribution patterns of Plutella xylostella (Lepidoptera: Plutellidae) in a fine-scale agricultural landscape based on geostatistical analysis
TLDR
It is demonstrated that Brassica vegetables distribution and growth stage, have dominant impacts on the spatial distribution of P. xylostella in a fine-scale landscape, and the distribution model developed by geostatistical analysis can provide a scientific basis for precise targeting and localized control of the diamondback moth.
