    Notes: Abstract The influences of esfenvalerate on mite behaviour were investigated by image analysis. Video recordings of the locomotory behaviour of two mite species were converted into a series of x,y coordinates that, when joined, closely resembled their paths. These coordinates were used to calculate walking speed, direction of travel, turning frequency, turn bias and tortuosity. Two experimental arenas were used: (1) a leaf disc arena for the European red mite, Panonychus ulmi and (2) a glass coverslip arena for Typhlodromus pyri. The behavioural responses of P. ulmi and T. pyri to esfenvalerate (field rate) indicated that these mites did not show a preference for the unsprayed halves of the arenas during the first 48 min. However, significant differences between most of the behavioural parameters to esfenvalerate residues were found with P. ulmi when whole arenas were compared. © Rapid Science Ltd. 1998

    Notes: Abstract Four fluvalinate formulations differed in their residual toxicity to female two-spotted spider mite (TSM), Tetranychus urticae adults; the emulsifiable concentrate (EC) was the most toxic. In contrast, there was little difference in toxicity between the formulations with the European red mite (ERM) Panonychus ulmi with the exception of the EC formulation which was the least toxic. Fluvalinate 2F caused minimal (〈10%) TSM and ERM egg mortality. Fluvalinate 2F was more toxic and caused greater larval dispersal for the TSM compared to the ERM at the field concentration and below. The toxicity of fluvalinate 2F to TSM and ERM protonymphs, deutonymphs and adults was low, approximately 〈20% at field concentration. Dispersal was the main response to fluvalinate and this was positively correlated with increasing concentration. The combined mortality and dispersal LC50 was five times lower for ERM protonymphs and adults, but 11 times higher for ERM deutonymphs compared to equivalent TSM life stages. Fluvalinate 2F reduced TSM development from the protonymph and deutonymph stages to a greater extent compared to the ERM. The mortality response to fluvalinate 2F was unaffected by host type (peach or apple) for the TSM whereas ERM mortality was higher on apple compared to peach. TSM dispersal was higher from apple compared to peach whereas ERM dispersal was similar on both host types. Oviposition by both mite species was lower on apple than peach leaves. A 1 h exposure to fluvalinate 2F reduced ERM oviposition for 12 days.

    Description / Table of Contents: Résumé La punaise,Nabis kinbergii Reuter est rencontrée communément dans les champs de luzerne à la fin de l'été et durant l'automne en Nouvelle Zélande. Son potentiel en tant que prédateur des espèces communes d'insectes ravageurs n'a pas encore été étudié. Ce travail rend compte de la roponse fonctionnelle des femelles adultes et des 5e stades larvaires de cette punaise vis-à-vis de deux espèces proies, le miride:Sidnia kinbergi (Stal) et le puceron du pois:Acyrtosiphon pisum (Harris). Une équation deHolling (1959) de type II définit bien la réponse fonctionnelle de ce prédateur sauf lorsque les 5e stades n'ont que des nymphes du Miride pour proie. Cette punaise,Nabis kinbergii manifeste des réponses identiques à celles d'un autreNabidae: Reduviolus americoferus (L.).
    Notes: Abstract The functional responses of adult and 5th instar Pacific damsel bug,Nabis kinbergii Reuter were determined under laboratory conditions using Australian crop mirid,Sidnia kinbergi (Stal), and pea aphid,Acyrthosiphon pisum (Harris) as prey.Holling's (1959) type II equation was found to adequately define the functional response of this predator except when 5th instar nymphs were provided with Australian crop mirid as prey. In this instance, a type III response was found.

    Notes: Abstract Ethyl nicotinate was found to be a potent attractant forThrips obscuratus in peaches and apricots. The male-to-female ratio in traps was 1∶8. The chemical was more attractive than ripe fruit, with peak catches at harvest. Season-long trapping showed the efficiency of the chemical compared to unbaited traps. The chemical remained attractive for at least 2 weeks when 50 μl were placed in open 2-ml vial caps. Various pyralids, geometrids (Lepidoptera), and chironomids (Diptera) were also attracted in low numbers to ethyl nicotinate.
