      Pages: 131 - 144
      Abstract: A review of the current knowledge on the diversity of inquiline oak gall wasps (Hymenoptera: Cynipidae: Cynipinae) from Colombia is conducted for the first time. A new species, Synergus dawnus Lobato-Vila and Pujade-Villar, is formally described and illustrated, and an undescribed specimen from the same genus is diagnosed and discussed. New biological, morphological, and distribution data of the only two previously known species from this country (Synergus colombianus Nieves-Aldrey, 2005 and Synergus pedroi Pujade-Villar, Lobato-Vila, and Fernández-Garzón, 2017), as well as an identification key to the Colombian species of Synergus Hartig, 1840, are provided. The morphological variability of the Colombian species of Synergus, especially of S. pedroi, is discussed.

      Abstract: Eclosion times and rates of Rhagoletis tabellaria (Fitch) (Diptera: Tephritidae) and its parasitoid wasp Utetes tabellariae (Fischer) (Hymenoptera: Braconidae) held at different chilling durations were determined in the laboratory. Adult fly and wasp longevity were also determined. Adult female and male flies from R. tabellaria puparia chilled for 195 days at 4.8 °C and then held at 23.2 °C eclosed on average earlier than U. tabellariae reared from R. tabellaria puparia. Rhagoletis tabellaria also eclosed significantly earlier from puparia chilled for 150 days than 120 days at 2.7 °C, but U. tabellariae eclosion from the two treatments did not differ significantly. Rhagoletis tabellaria eclosion rates were greater with longer chill durations, but U. tabellariae eclosion rates per R. tabellaria puparium did not differ among chill durations. No R. tabellaria eclosed from nonchilled puparia held at 20–22 °C, but at least 18.8% of nonchilled U. tabellariae eclosed. Female and male R. tabellaria on average survived 52.1 and 83.3 days, respectively, while female and male U. tabellariae survived 37.7 and 28.7 days, respectively. Results indicate diapause and developmental traits of R. tabellaria may be more dependent on chilling durations and less flexible than those of U. tabellariae, a wasp that appears adapted to flies in the R. tabellaria species complex.

  • Effect of temperature, population density, and sex on feeding damage
           caused by adult pea leaf weevil (Coleoptera: Curculionidae)
    • Authors: Vivian Morley-Senkler; Jonathon Williams, Meghan Vankosky
      Pages: 159 - 168
      Abstract: Sitona lineatus (Linnaeus) (Coleoptera: Curculionidae) is an important pest of Pisum sativum Linnaeus (Fabaceae) and Vicia faba Linnaeus (Fabaceae). Managing S. lineatus is difficult. There is currently no forecast that can be used to predict S. lineatus population densities between growing seasons (when management decisions are made). Sitona lineatus populations are monitored in spring by assessing adult-induced feeding damage. We assume the quantity of feeding damage is indicative of population density. However, the effects of abiotic factors, including temperature, on feeding rate are not known. We assessed the effects of temperature, population density, and sex on S. lineatus feeding rate by counting feeding notches on host plants exposed to adult weevils for 24 hours at four densities and under five temperature regimes. Individual females consumed more than male weevils. As expected, feeding damage increased with weevil density. The influence of temperature increased as weevil densities increased. Feeding rate did not differ between constant and fluctuating temperature regimes of equal mean daily temperature. Thus, a model based on mean daily temperature may predict weevil density if temperature and damage levels are known. Historical survey data for S. lineatus could be used to develop and validate new models.

      Abstract: Eriococcus spurius (Modeer) (Hemiptera: Eriociccidae) is a pest of American elm (Ulmus americana Linnaeus; Ulmaceae) trees in western North America, but no effective biological control agent has been reported. This study took place in Calgary, Alberta, Canada, where urban American elms have been heavily and negatively impacted by E. spurius. Although the parasitoid Coccophagus gossypariae Gahan (Hymenoptera: Aphelinidae) was recovered from an E. spurius infested American elm in Calgary, little is known about its ecology. Prior to implementing biological control, the basic ecology of a candidate species must be understood. We documented the geographic establishment, sex ratios, and parasitism rate of C. gossyparaie on its host within the study area. Coccophagus gossypariae had established at 89% of study trees sampled and accounted for 98% of the parasitoids caught. They had a female-biased sex ratio of 13.7 females per male, and both males and females developed to maturity using the host. We found evidence of a highly consistent aversion to superparasitism by females in the field. This first investigation established a baseline of information on field populations of C. gossypariae that could lead to biological control of E. spurius.

      Abstract: The invasive alien Scolytus schevyrewi Semenov (Coleoptera: Curculionidae: Scolytinae) was detected in Saskatchewan and Manitoba, Canada, in 2007. Because S. schevyrewi is a potential vector of the Dutch elm disease pathogen (Ophiostomanovo-ulmi Brasier; Fungi: Ophiostomataceae), the natural history of the beetle was studied from 2009 to 2012 in the two provinces, where the disease is managed to protect Ulmus americana Linnaeus (Ulmaceae). Typically, healthy trees become infected when their xylem is contacted during feeding by spore-bearing scolytine adults that have flown from a diseased tree; adults emerging from brood galleries in diseased trees frequently carry spores. We caught flying S. schevyrewi adults from May to October; adults were weakly attracted to healthy Ulmus Linnaeus but were strongly attracted to Ulmus pumila Linnaeus stressed by girdling. Scolytus schevrewi colonised and completed development in girdled trees and trap logs of U. pumila. In contrast to other studies, U. americana – the major source of pathogen spores in the area – was never colonised as a brood host. Our results suggest that S. schevyrewi will primarily use U. pumila, which, in Manitoba and Saskatchewan, seldom exhibits symptoms of Dutch elm disease. Thus, arrival of S. schevyrewi does not appear to require changes to Dutch elm disease management programmes.

      Abstract: The dynamics of interactions amongst natural enemies are central to the investigation of insect pest ecology. Ternary and quaternary interactions between parasitoids and predators in the presence of entomophagous organisms are yet to be comprehensively explored. We investigated the performance of a clone of green peach aphid (Myzus persicae (Sulzer); Hemiptera: Aphididae), raised on savoy cabbage (Brassica oleracea Linnaeus; Brassicaceae), under all possible combinations of: I) the parasitoid Aphidius colemani Viereck (Hymenoptera: Braconidae); II) the predator Chrysoperla carnea (Stephens) (Neuroptera: Chrysopidae); III) the predator Adalia bipunctata (Linnaeus) (Coleoptera: Coccinellidae); and IV) the spider Parasteatoda tepidariorum (Koch) (Araneae: Theridiidae). We demonstrate a considerably differential green peach aphid abundance, polyphenism, and fine-scale spatial distribution in response to the combination, number, and identity of the present enemy species and their interactions. Surprisingly, certain combinations led to thriving green peach aphid populations due to interference between enemies; whereas, other combinations resulted in tangible collective suppression of the population. At the frontier of agroecology and entomology, we provide fresh insights on the effects of conflict and synergy between natural enemies sharing a pest of a cash crop as prey, highlighting the consequences of the presence of a novel synanthropic spider, as a top predator, on pest regulation.

      Abstract: The role of spiders (Arachnida: Araneae) in biological control programmes has received less attention than that of insect natural enemies. The aim of this two-year study was to obtain descriptive data on spider spring field population structure and dynamics. The study was carried out in one insecticide-free and four organic apple orchards in southeastern France. Rolls and bands of corrugated cardboard near the ground and shoots infested with Dysaphis plantaginea (Passerini) (Hemiptera: Aphididae) in the tree canopy were used to sample spiders. Thirty-three spider species belonging to 14 families were identified from both sampling methods. Cheiracanthium mildei Koch (Araneae: Cheiracanthiidae) was clearly the predominant arboreal spider species in aphid-infested shoots (>57%). More than half of the spiders recorded in cardboard bands belonged to three species Drassodes pubescens (Thorell) (Araneae: Gnaphosidae), Pseudeuophrys erratica (Walckenaer) (Araneae: Salticidae), and Icius hamatus (Koch) (Araneae: Salticidae). Salticidae (39.9%) and Gnaphosidae (23.4%) families dominated significantly the spider assemblages observed in the cardboard rolls and were present on almost all sampling dates. However, in the two shelter types, the spider abundance curve clearly had a poly-modal shape. This may be due to the sequential arrival of some spider species or their dominance in a certain period of our study.

      Abstract: Blueberry maggot (Rhagoletis mendax Curran (Diptera: Tephritidae)) is a pest of blueberries (Vaccinium Linnaeus (Ericaceae)). Tephritid flies, including Rhagoletis Loew species, are susceptible to entomopathogenic fungi, but mortality levels depend on life stage targeted. We tested Metarhizium anisopliae (Metschnikoff) (Clavicipitaceae) strain S54 by application to pupae in the laboratory and using soil drenches in the laboratory and field. We hypothesised that younger (pre-diapause) pupae would be more susceptible to infection than older (post-diapause) pupae. In the laboratory, R. mendax emergence was reduced from 80% in the control to 57–60% with M. anisopliae. Rhagoletis mendax longevity was reduced by two days for both application timings, and mycosed cadavers increased by 9% and 27% with applications to younger and older pupae, respectively, compared to controls. In the field, R. mendax emergence was reduced by 50% with application to younger pupae compared to controls and applications to older pupae. The surfactant Silwet L77 caused reduced R. mendax emergence when pupae were dipped in suspensions. Even though M. anisopliae S54 did not greatly reduce emergence or longevity, infection was successful and younger pupae may be more susceptible than older pupae. Research with other M. anisopliae isolates against multiple life stages should be conducted and effects of soil variables on pathogenicity determined.

      Abstract: The cyclamen mite (Phytonemus pallidus Banks; Acari: Tarsonemidae) has recently become a more important pest in Canadian strawberry (Fragaria × ananassa Duchesne ex Rozier; Rosaceae) production with the withdrawal of the pesticide endosulfan in 2016, yet its phenology under field conditions in Canada is poorly known. Moreover, while its biological control with predatory mites has shown potential, the effectiveness of this method has never been investigated under eastern Canadian field conditions. The objectives of this study were to (1) monitor populations of P. pallidus in strawberries for two consecutive years; and (2) evaluate the in-field potential of the predatory mite Neoseiulus cucumeris Oudemans (Acari: Phytoseiidae). Monitoring cyclamen mite populations in the field revealed new critical knowledge about its phenology in eastern Canada, such as activity until late November. The predator N. cucumeris was able to effectively suppress cyclamen mites the first year, but appeared to be too cold-sensitive to maintain adequate control towards the end of the season. Furthermore, the high rates of predator release required would most likely be cost prohibitive for commercial use. Control of the cyclamen mite in strawberries remains a complex issue that will require further research.

      Abstract: We examined the use of bulk mass to predict the number of individuals in samples of the dung beetle Chilothorax distinctus (Müller) (Coleoptera: Scarabaeidae: Aphodiinae: Aphodiini). We first developed linear regression equations to characterise the relationship between the number of beetles in a sample and sample wet mass, air-dried mass, or oven-dried mass. We then applied these equations to samples containing unknown numbers of beetles to obtain a predicted number. The predicted number was subsequently compared to the number obtained by counting each beetle by hand. Wet mass was as suitable as air-dried or oven-dried mass to estimate beetle numbers and was quicker to obtain. The predicted number of beetles in individual samples based on wet mass deviated from the actual number by 0.6–19.9%. For results combined across samples, the discrepancy was 2.2%. We conclude that quantifying C. distinctus by bulk wet mass rather than by hand count provides a reasonable alternative that accelerates the pace of sample processing while providing substantial cost savings. These results add to the small body of literature assessing the accuracy of bulk insect mass as a predictor for the actual number of individuals in large samples of conspecifics.
