Control of brown dog tick, Rhipicephalus sanguineus was attempted by utilizing sustained release preparations of synthetic analogues of assembly pheromones. The assembly pheromone, in defined ratio, was encapsulated using poly-ɛ-caprolactone by water-in-oil-in-water double emulsion solvent evaporation technique. In the in vitro bioassay, percent mortality with test microspheres was 95.6, 64 and 44 among the unfed larvae, unfed nymph and unfed adults respectively, 24 hours post-exposure. Field trials were carried out to evaluate the efficacy of microspheres in luring and killing environmental stages of R. sanguineus in dog houses/kennels. Engorged and unfed stages in the environment were found adhered and dead on the specially designed lure.

The trials conducted with selected chemical and biological insecticides in 1998-2000 showed the highest effectiveness of Karate Zeon 100 CS (lambda-cyhalotrine) in European corn borer (ECB) larvae control in sweet corn. The efficacy of biological insecticides containing Bacillus thuringiensis ssp. kurstaki: Biobit 3.2 WP and Lepinox WDG was very variable between the years. Reasons for insufficient efficacy of these products are discussed. The most appropriate time for the application of a chemical insecticide against ECB larvae are plant developmental stages since the beginning of pollen shedding to full blooming (63–67 BBCH scale). The efficacy of treatment was the highest at that time.

Over the past several years my colleagues and I have been exploring ways of achieving moth mating disruption exceeding 95% efficacy even under high densities with limited insecticide inputs. The foundation for this work has been a series of studies examining the mechanisms underlying pheromone-based mating disruption in moth pests of pome fruit, stone fruit, walnuts, and citrus. Collectively, the results support competitive attraction or false-plume-following as an essential component of communicational disruption of moths in the family Tortricidae. Habituation of central nervous system (CNS) response appears to be an important supplementary mechanism for moths having oriented along plumes of high-dosage dispensers. Four main lines of evidence have led to these conclusions. Pheromone-based disruption of moths is density-dependent. Under high population densities, disruption increases as a function of increasing density of pheromone release sites. Effective mating disruption using high-dosage dispensers occurs in the field despite overall atmospheric concentrations not reaching levels high enough to desensitize moths by adaptation or habituation without close range (within cm) exposure to high dosage dispensers. Males are attracted to high-dosage dispensers in the field and such encounters desensitize the CNS but do not affect sensitivity of the peripheral nervous system. If competitive attraction followed by CNS habituation are the combined mechanisms achieving mating disruption, the following practical implications should be considered for developing high performance approaches and formulations: 1) distribution of dispensers should be uniform rather than clumped, 2) dispenser density should be high, and 3) release rate from synthetic dispensers should be within a physiologically attractive range but also sufficiently high to habituate male moth response following orientation.

The aim of this study was to examine whether and how different odorants placed on the bodies of female mice, but having no reward value for the males, affect courtship and mating behaviour of male mice towards females in oestrus and thus emitting female pheromones. In this manner, certain consequences of concurrent activation of the main olfactory system and the vomeronasal system were investigated. Four different odorants (white musk, lavender, peppermint and valerian) were used for swabbing female mice in oestrus. Using a total of 160 sexually naive outbred mice of both sexes, divided for each of 4 odorants into controls (not swabbed with odorant) and two experimental groups, in the experimental group I the females observed previously as controls were swabbed with one of the 4 odorants, while in the experimental group II, new naive females were swabbed with one of the 4 odorants. The females were observed in individual cages for 30 min. each, together with a respective sexually naive male. The latency between introduction of a male into a cage with a previously swabbed female and initiation of courtship and mating behaviours by males (sniffing, circling, misdirected mounting, copulation failures, successful copulation) was recorded. Latency to the occurrence of all sexual behaviours was significantly longer in experimental groups compared to controls. Latency to initiation of courtship behaviour, especially sniffing and circling, was shorter towards females swabbed with peppermint odour than for other odorants, indicating no aversion to this odour. However, the peppermint odour completely inhibited copulation. It is concluded that alien volatile odours with no reward value nevertheless exert differentiated suppressing effects on female mice pheromones inducing courtship and mating behaviour. Thus, it is hypothesized that the activation of the main olfactory system suppresses the accessory vomeronasal system.

This study was designed to establish: a) whether boar pheromones, androstenone and androstenol, may affect the vasocontractility of the facial superficial veins in ovariectomized pubertal gilts and b) what is the effect of estradiol on this contractility. The gilts ovariectomized after two controlled estrous cycles, and the ovariectomized gilts treated with estradiol benzoate were used in the experiment. The isolated rings of dorsal nasal, frontal and facial veins were incubated with androstenone (5a-androst-16-en-3-one) and androstenol (5a-androst-16-en-3-ol) in concentrations of either 1 or 10 μM. Changes in the contractile activity of the isolated vein segments were measured using isometric transducer and recorded with HSE-ACAD W software. In ovariectomized gilts both the androstenone and androstenol caused a relaxing effect on the nasal vein, flow of the blood from the nasal cavity, and on the frontal vein, by which the blood may by directed into the perihypophyseal vascular complex. An opposing reaction to these pheromones was found in the distal part of the facial vein by which the blood is directed to the systemic circulation. Treating ovariectomized gilts with estradiol benzoate changed mainly the reactivity of the frontal vein to androstenone, which produces constriction, but this treatment did not affect the reactivity of the facial superficial veins to androstenol. The present results demonstrated that both boar sex pheromones, androstenone and androstenol, may contribute to the regulation of their humoral pathway from the nasal cavity to the brain and hypophysis in the ovariectomized pubertal gilts and suggest the effect of estradiol to this pathway.
