Entomopathogenic nematode interactions with white grubs from forest and sugarcane plantations
In South Africa, white grubs are important pests of sugarcane and wattle. There is need for a sustainable management alternative since their control has mainly been through the use of chemical insecticides. Such alternatives can include the use of entomopathogenic nematodes, EPNs. A review of the …

Efficacy of Entomopathogenic Nematodes and Entomopathogenic Fungi against Masked Chafer White Grubs, Cyclocephala spp. (Coleoptera: Scarabaeidae)
… evaluated for efficacy against masked chafer white grub, Cyclocephala spp., under laboratory and greenhouse conditions, as well as their efficacy against various grub stages in the field. Under both laboratory and greenhouse conditions, additive interactions were found between EPN and EPF in …

Interactions of insecticides, entomopathogenic fungi, and earthworms as they relate to white grub IPM in turfgrass systems
White grubs (Coleoptera: Scarabaeidae) are important turfgrass pests in Virginia. Insecticides such as the neonicotinoid imidacloprid are commonly applied to turfgrass in order to control these pests. As an alternative to synthetic insecticides, entomopathogenic fungi (EPF), including Metarhizium …

Pest Management Studies of Early Season and Stalk-Boring Insects on Corn in Virginia
… of early season soil insects, specifically white grubs (Coleoptera: Scarabaeidae) and wireworms (Coleoptera: Elateridae) in cornfields. In the first study, model variables included corn growth stage and larvae per plant. In both years of this study, larvae per plant had a significant effect …

Spatial factors affecting white grub presence and abundance in golf course turf
… was initiated with four rounds of sampling for white grubs on the fairways of nine golf courses located on the Lower Peninsula of eastern Virginia, from 2000 through 2002. Fifteen regressor variables were collected and measured that included local-scale variables, golf course management …

Species composition and larval instar population structure of Scarabaeids in forestry in the Natal Midlands
White grub is the common name of most scarabaeid larvae and some are considered ! as grubs of economic importance to agricultural crops. Expansion of forestry into previous croplands has resulted in some pests of previous agricultural crops becoming important in forestry. Field trials planted over …

Spatial distribution of western corn rootworm (Diabrotica virgifera virgifera Leconte) trap counts and evaluation of a novel method for sampling soil pests of field corn
… including seedcorn maggots, wireworms, and white grubs. No one method has yet been developed to sample all of the insects in the guild. A new method, the baited wire trap (BWT), was evaluated in 47 fields in 1990 and 1991. No significant differences were found between the proportion of seeds …

Novel natural product based anti-anxiety therapy and natural insecticides
… of pests including mosquitoes, earwigs and white grubs. Moreover, the P. tuberculatum extracts were as effective as the well-documented Asian (P. nigrum) and African ( P. guineense) Piper species. Piperamides (25)--(28) were synthesized in sufficient amounts to allow extensive evaluation of …

Trophic dynamics in the fine-root based food web: integrating resource heterogeneity, root herbivores, and root foraging
Resources in the soil are heterogeneously distributed. We know that plant species differ in their root responses to nutrient patches and that these differences in foraging can influence plant competition. However, most studies of root-resource interactions overlook the potential top-down influence …
