Behavioral Changes in Japanese Beetle and Masked Chafer Grubs (Coleoptera: Scarabaeidae) After Parasitism by Tiphiid Wasps (Hymenoptera: Tiphiidae)
We studied effects of parasitism by two Tiphia species (Hymenoptera: Tiphiidae) on burrowing behavior of their respective scarabaeid hosts and tested the hypothesis that parasitoid alteration of host hormones accounts for the observed behavioral change. In turf Þeld-plots, thirdinstar masked chafer grubs, Cyclocephala sp., parasitized by native Tiphia pygidialis Allen burrowed to depths of 12Ð1...
متن کاملIncidence of Non-Immunological Defenses of Soil White Grubs on Parasitism Success of Mallophora ruficauda Larva
White grubs are larvae of Coleoptera of the family Scarabaeidae. They are known because of their intensive feeding habits on crop roots. Mallophora ruficauda (Diptera: Asilidae) is a dipteran parasitoid whose larva is a natural enemy for white grubs. This species is a solitary ectoparasitoid, where both female and larva realize different steps in the host location process. Female place its eggs...
متن کاملAcoustic estimation of infestations and population densities of white grubs (Coleoptera: Scarabaeidae) in turfgrass.
Incidental sounds produced by Phyllophaga crinita (Burmeister) and Cyclocephala lurida (Bland) (Coleoptera: Scarabaeidae) white grubs were monitored with single- and multiple-sensor acoustic detection systems in turf fields and golf course fairways in Texas. The maximum detection range of an individual acoustic sensor was measured in a greenhouse as approximately the area enclosed in a 26.5-cm-...
متن کاملBiology of Tiphia pygidialis (Hymenoptera: Tiphiidae), a Parasitoid of Masked Chafer (Coleoptera: Scarabaeidae) Grubs, with Notes on the Seasonal Occurrence of Tiphia vernalis in Kentucky
We investigated the biology of Tiphia pygidialis Allen, a previously unstudied native parasitoid of masked chafer, Cyclocephala spp. grubs, in central Kentucky and the seasonal dynamics of Tiphia vernalis Rohwer, an introduced parasitoid of Japanese beetle, Popillia japonica Newman. T. pygidialis was active from mid-August to early October, parasitizing third-instar masked chafers, whereas T. v...
متن کاملIdentifying and Managing White Grubs in Turf
White grubs are the larval stage of several scarab beetle species that feed on grass roots causing wide variation in damage. Last fall, we saw an abundance of white grub damage around Vermont, so it is likely, that we will see more damage this spring and summer. However, grub damage can vary significantly from year to year and we know that turf that receives adequate water and has a healthy roo...
