Abstract (sommario):

The wasps Anaphes victus (Huber) and Anaphes listronoti (Huber) [Hymenoptera : Mymaridae] parasitize 50% of the eggs of carrot weevil, Listronotus oregonensis (Le Conte) [Coleoptera : Curculionidae] in Quebec and in Ontario. Attempts to detect either of these egg parasites from exposed carrot weevil eggs in Nova Scotia were unsuccessful. However, 48 individuals of a new species of parasitic wasp, Anaphes sp. nov. [Hymenoptera : Mymaridae], were detected in carrot (Daucus carota) fields in Nova Scotia, using carrots infested in growth chambers with carrot weevil eggs. Anaphes sp. nov. is distin

AbstractBradynema listronoti is a parasitic nematode described from infected specimens of the carrot weevil Listronotus oregonensis. Prevalence of infection by B. listronoti under field conditions was followed over a period of 16 years in an untreated carrot field. Susceptibility of different carrot weevil life stages was evaluated as well as the impact of infection on fecundity and mortality. Gene expression in infected and uninfected carrot weevils was also compared to evaluate the impact of the parasite on the host transcriptome. Prevalence of B. listronoti in carrot weevil populations was

Abstract (sommario):

AbstractBradynema listronoti n. sp. was collected from the haemocoel of adults and the environment of the carrot weevil, Listronotus oregonensis in Quebec, Canada. It is the first species of Bradynema to be reported from weevils and is described and illustrated herein. Bradynema listronoti n. sp. appears to be closest to B. trixagi because of the shared characteristic of a peloderan bursa in males which is not present in the other seven described species in the genus. Bradynema listronoti n. sp. can be differentiated from all members of the genus by the possession of a degenerate, but sometime

Abstract (sommario):

   A laboratory study was conducted to: (1) advance earlier work to determine the susceptibility of Listronotus bonariensis (Argentine stem weevil) to its parasitoid biological control agent, Microctonus hyperodae, in the presence of diploid ryegrasses such as Lolium multiflorum or Lolium perenne; and (2) determine whether or not plant orientation (i.e. horizontal vs. vertical) had any effect on parasitism rates. No significant differences in parasitism rates were found in the Listronotus bonariensis populations in the two grasses. However, combining and analysing these data

Abstract (sommario):

The effect of temperature during host patch exploitation by parasitoids remains poorly understood, despite its importance on female reproductive success. Under laboratory conditions, we explored the behaviour of Anaphes listronoti, an egg parasitoid of the carrot weevil, Listronotus oregonensis, when foraging on a host patch at five temperatures. Temperature had a strong effect on the female tendency to exploit the patch: A. listronoti females parasitized more eggs at intermediate temperature (20 to 30°C) compared to those foraging at the extreme of the range (15.9°C and 32.8°C). However, ther

AbstractFlight byListronotus bonariensis(Kuschel) in Canterbury, New Zealand varied greatly both within and between seasons; no winter flight was detected between mid-May and mid-August. Predisposing conditions for flight were found to be >19degC, rh <81% and windspeed <10.8 km h–1. Three flight phases with different characteristics were identified when approximately equal numbers of weevils were trapped. These were between mid-August and early December (overwintered weevils), between early December and mid-March (first summer generation weevils) and mid-March and mid-May (first and s

Abstract (sommario):

Listronotus montanus (Dietz) is a little known species, distributed in central North America. O'Brien and Wibmer (1982) record its occurrence from Indiana west to Nevada and north to the Prairie Provinces. In Montana, it occurs widely in grasslands east of the Continental Divide (Montana Entomological Collection, unpublished), but is also recorded from Saunders Co. in western Montana (Russell 1968). Nothing has been reported on the biology of this species, but it has been observed on grasses in the Cypress Hills of Alberta (CWOB unpublished). We report the occurrence of this species as a poten

Abstract (sommario):

The time-varying survival rates of the carrot weevil, Listronotus oregonensis, were estimated by a new method. This method precluded the possibility of negative simulation survival rates. Analysis of carrot weevil population dynamics indicated that the egg mortality was density dependent with Anaphes sordidatus, an egg parasitoid, as a major density dependent factor. Larval mortality was less density dependent. Based on the mortality information, a simulation model for carrot weevil population dynamics was established. The simulation precision, evaluated by comparing simulated and observed egg

Mortality and frass bioassays using a suitable semi-artificial diet showed strains A30, A429 and BTT to be highly toxic. Mortality persisted after initial exposure to the bacteria with the survivors not resuming normal feeding. Attempts to reisolate B. thuringiensis from the insects revealed B. thuringiensis-like organisms in the gut and in/on other structures. At the midgut pH of the insect (pH 8.0), the crystals of the toxic strains we

Abstract (sommario):

Some aspects of the presence of systemic endophytic fungi in agriculturally important New Zealand grasses were studied in relation to plant breeding. Seedling resistance to adult Argentine stem weevil feeding in perennial ryegrass, Italian ryegrass and tall fescue was found to be related to the presence of their respective Acremonium endophytes in the seed rather than to plant genetic resistance. In addition a study of perennial ryegrass revealed that this resistance was independent of endophyte viability.

Abstract (sommario):

Listronotus maculicollis (Dietz) is a major pest of golf course turf in the northeastern United States. Because the larval stage of this insect causes considerable damage to short-mowed turfgrass, such as tees, greens, fairways, golf course superintendents rely on chemical applications for control. I investigated physiological, ecological, and behavioral characteristics of L. maculicollis to enhance management strategies that will lead to reduced insecticide inputs in golf course turf. Among the cool season turfgrass species, L. maculicollis larvae are reportedly found primarily in Poa annua L
