- Abstract:
- ... The relationship between oviposition preference and larval performance is a central topic in insect-plant biology. In this study, we investigate whether the oligophagous flea beetle, Altica fragariae Nakane (Coleoptera: Chrysomelidae), exhibits a positive preference-performance relationship, and whether oviposition preference develops over time. We tested the beetles using four sympatric plant spe ...

- Abstract:
- ... Selenium (Se) is an essential micronutrient for vertebrates though little is known about the effects on insects. Herbivorous insect larvae acquire Se from plant tissues in the inorganic form of sodium selenate and sodium selenite, and in the organic form of selenoamino acids, selenomethionine, and selenocystine. In this study, we document the effects of dietary supplementation with sodium selenite ...

- Abstract:
- ... Among numerous other factors, host-plant volatiles may affect selection of food plants by herbivorous insects. The blue willow leaf beetle, Phratora vulgatissima (L.) (Coleoptera: Chrysomelidae), is known to differentiate between willow species and genotypes. However, so far no knowledge is available on the physiological abilities of this leaf beetle to respond to willow volatiles. In this study, ...

- Abstract:
- ... Males and females of the common bed bug, Cimex lectularius L. (Heteroptera: Cimicidae), have been shown to produce and respond to an aggregation pheromone. We tested whether juvenile C. lectularius also produce and respond to aggregation pheromone, and whether the pheromone is perceived by contact chemoreception. In dual-choice laboratory experiments, juveniles, but not males or females, preferred ...

In laboratory and garden experiments, we tested for the existence of adaptive patterns of oviposition and larval behaviour regarding group size in the gregarious tortoise beetle Chelymorpha varians Blanchard (Coleoptera: Chrysomelidae: Cassidinae) on its host plant Calystegia sepium L. (Convolvulaceae). Specifically, we addressed the following questions: (i) Which is the more frequent egg cluster ...

- Abstract:
- ... Potato leafroll virus (PLRV; genus Polerovirus, family Luteoviridae) is a persistently transmitted circulative virus that depends on aphids for spreading. The primary vector of PLRV is the aphid Myzus persicae (Sulzer) (Homoptera: Aphididae). Solanum tuberosum L. potato cv. Kardal (Solanaceae) has a certain degree of resistance to M. persicae: young leaves seem to be resistant, whereas senescent l ...

Late instars of the Pacific Coast wireworm, Limonius canus (LeConte) (Coleoptera: Elateridae), were exposed to wheat seeds treated with tefluthrin at 5, 10, 15, 20, or 30 g active ingredient (a.i.) per 100 kg wheat seed for 1, 2, 4, 8, or 16 min. All wireworms were moribund within 20 min of first exposure and recovered fully within 12 h. The time required for recovery (tr) after a single exposure ...

Although the temperature-size rule, that is, an increase in egg (and body) size at lower temperatures, applies almost universally to ectotherms, the developmental mechanisms underlying this consistent pattern of phenotypic plasticity are hitherto unknown. By investigating ovarian dynamics and reproductive output in the tropical butterfly Bicyclus anynana (Butler) (Lepidoptera: Nymphalidae: Satyrin ...

- Abstract:
- ... The effects of global warming on the life cycle and life-history traits of the fall webworm, Hyphantria cunea (Drury) (Lepidoptera: Arctiidae), were investigated in Fukui, Japan. Our previous studies showed that the Fukui population had a predominantly bivoltine life cycle, but recently the life cycle has changed. In the present study, the life-history traits of individuals collected in 2002 in Fu ...

- Abstract:
- ... Rhyzopertha dominica (F.) (Coleoptera: Bostrichidae) is a serious worldwide pest of stored cereal grains that also has the ability to breed in non-agricultural host plant material. Stable isotope signatures (concentrations of isotopes) were used as internal tissue markers to determine dietary differences among adult R. dominica and to make inferences about source habitats of field-trapped insects. ...

- Abstract:
- ... Blends of volatile compounds emitted by host plants are known to mediate the attraction of gravid female herbivores to oviposition sites, but the role of individual odor components is still little understood. We characterized the olfactory response of mated female Cydia (Grapholita) molesta (Busck) (Lepidoptera: Tortricidae) to synthetic mixtures of compounds emitted by peach shoot, a key host pla ...

- Abstract:
- ... Two phenomena are integral to the foraging behaviour of leaf-cutting ants in the genus Atta: hitchhiking (where small ants ride on leaf fragments carried by larger workers) and rhythmic foraging (where foraging activity shows marked fluctuations over time). While parasitism by phorid flies has been implicated in eliciting both behaviours, recent research suggests fungal contaminants and the need t ...
