Agricultural cover was positively associated with fluctuating asymmetry in Trypoxylon opacum, suggesting a possible increase in developmental instability in intensively managed landscapes. Wing size was positively related to forest cover and negatively related to agricultural cover, indicating that forested landscapes may promote larger body size ...

Biological traits of Quadrastichus mendeli (Hymenoptera, Eulophidae), parasitoid of the eucalyptus gall wasp Leptocybe invasa (Hymenoptera, Eulophidae) in Thailand [PDF]
Quadrastichus mendeli Kim & La Salle, a parasitoid of Leptocybe invasa Fisher & La Salle, is a uniparental species. This study assessed the biological traits of Q. mendeli in the laboratory at a temperature of 27 ± 1 °C. Diets had a highly significant effect on the mean longevity of female Q. mendeli.

In a given number of samples, grassland sward islets contain more species of arthropods than the surrounding sward. When corrected for abundance, there is no difference in species richness, suggesting that the effect of islets might purely be to concentrate arthropods. The community structure differences indicated by non‐metric multidimensional scaling

Evaluation of Experimental Populations and Glandular-Haired Varieties of Alfalfa for Alfalfa Blotch Leafminer (Diptera: Agromyzidae) Feeding Injury [PDF]
Following the spread of the alfalfa blotch leafminer, Agromyza frontella (Rondani) (Diptera: Agromyzidae), into Minnesota and Wisconsin U.S.A. during 1994-1997, three field trials were conducted in Minnesota to assess the potential for leafminer ...

Drying processes in the Brazilian palm swamps or Veredas, impact the gall community in adjacent vegetation by reducing the abundance of more sensitive galls, while more resilient galls acclimate to increased dryness by developing thicker protective tissues. Abstract Galls are new plant organs formed in response to the stimuli of gall‐inducing organisms,

Insects Associated with Michigan Bumblebees (\u3ci\u3eBombus\u3c/i\u3e Spp.) [PDF]
(excerpt) Studies of insect associates of bumblebees are not new. For example, Tuck (1896, 1897) reported over 50 species of insects associated with nests of British bumblebees. Sladen (1912) discussed nest associates and parasites of European bumblebees,

Insect biological control of the tomato‐potato psyllid Bactericera cockerelli, a review
ABSTRACT The tomato‐potato psyllid (TPP) Bactericera cockerelli is a polyphagous herbivore and a renowned pest of solanaceous crops found in America and the Pacific region. Over the last fifteen years, several strategies have been tested worldwide to successfully manage this species, but these have been mostly unsuccessful.

ABSTRACT Parasitoid insects can significantly influence the dynamics of terrestrial ecosystems due to their interactions with phytophagous insects. Tortoise beetles (Cassidinae s. str., Coleoptera, Chrysomelidae) are one of the most parasitized groups of Coleoptera.

Role of spontaneous plants as a reservoir of alternative hosts for Semielacher petiolatus (Girault) and Citrostichus phyllocnistoides (Narayanan) (Hymenoptera, Eulophidae) in citrus groves [PDF]
The role spontaneous plants could eventually play towards populations of two exotic parasitoids, Semielacher petiolatus (Girault) and Citrostichus phyllocnistoides (Narayanan), was investigated in five Sicilian citrus groves.
