    Notes: Abstract We used artificial selection experiments to study genetic allocation costs and physiological mechanisms of resistance to herbivory and fungal disease. Genetic costs to resistance were present in some instances and absent in others. Genetic resistance to the fungal pathogen, Leptosphaeria maculans was cost-free, while resistance to Peronospora parasitica showed a negative genetic correlation between disease resistance and growth rate. Leptosphaeria resistant genotypes had 13% higher chitinase activity. Genetic increases in myrosinase activity were correlated with increased resistance to flea beetles (Phyllotreta cruciferae), but resulted in lower plant fecundity, presumably due to production costs of myrosinase. Genetic costs of resistance may maintain genetic variation in natural plant populations. These studies demonstrate the predictive and explanatory power of a functional approach to plant-herbivore and plant-pathogen interactions.

    Notes: Abstract Lanierone strongly synergized the attraction of male and female Ips pini (Say) to ipsdienol in New York and Wisconsin. Synergy was only weakly significant in Montana and British Columbia and not significant in California. Catches of I. pini in ipsdienol-baited traps were increased 0% ( i.e., nonsignificant) to 9942% by lanierone, with the highest increases in eastern North America. Lanierone had the least effect in California. The effects of lanierone on sex ratios of I. pini in trap catches varied significantly between regions. The addition of lanierone to ipsdienol-baited traps resulted in a general increase in male representation at nine of 12 sites. Ips integer (Eichhoff) was attracted to lanierone alone. Ipsdienol reduced the response of I. integer to lanierone. Enoclerus lecontei (Wolcott) (Cleridae) preferred traps baited with the combination of ipsdienol and lanierone. (R)-(–)-Ipsdienol was attractive to E. sphegeus (F.), Thanasimus undatulus (Say) (Cleridae), and Temnochila chlorodia (Mannerheim) (Trogositidae), while racemic ipsdienol was attractive to E. nigrifrons var. gerhardi Wolc. and Thanasimus dubius (F.). Lanierone had no effect on these species.

    Notes: Abstract Studies were carried out in the laboratory on the influences of time of day, temperature, relative humidity and starvation on flight initiation byProstephanus truncatus (Horn) (Coleoptera: Bostrichidae). Flight occurred throughout the 12 h photophase and at the beginning of the scotophase but peaked at 2–0 h before darkness. Temperature exerted a significant effect on flight. The frequency of flight take-off increased with temperature over the range 20–30°C but declined sharply at 35°C. Flight activity increased with starvation up to a maximum at 2 days after which it began to decline.

    Notes: Abstract The chronic and acute toxicity of fumonisin B1 (FB1), a mycotoxin from Fusarium moniliforme, to the larvae of the yellow mealworm, Tenebrio molitor, was assessed. The toxin was administered via the diet or injected directly into the larvae. Young T. molitor larvae fed on a diet containing 450 µg FB1 per g diet exhibited reduced growth performance but only after consuming the fumonisin-contaminated diet for several weeks. FB1-contaminated diet also reduced the rate of carbon dioxide production, food consumption and protein metabolism. The concentrations of FB1 in the diet did not increase mortality, even when tested at the highest dose of 450 µg FB1 per g of diet. Injection of 25 ng FB1 per larva decreased the CO2 production, but became significant only 11 days after the injection and was reversible with time. A parallel analysis of the retention of FB1 by the larvae indicated that about 40% of the ingested FB1 was excreted in the faeces.

    Notes: Abstract Experiments were carried out in Uganda to optimise pheromone traps for the African sweetpotato weevil species, Cylas puncticollis Bohe. and C. brunneus F. (Coleoptera: Apionidae). Various designs of funnel, water and sticky traps were compared and a 5-l plastic jerry can trap was the most appropriate design for effectiveness and practicability. A solution of Omo detergent in water was found to be the most effective trapping agent. Fewer weevils were caught in red traps than in yellow, white, green or blue traps. Catches of C. puncticollis increased when the trap was raised above crop height, but catches of C. brunneus were unaffected. When marked weevils were dropped onto the trap, 36% of C. puncticollis and 23% of C. brunneus were captured, and, of weevils placed in the trap, 88% and 92%, respectively, of the two species remained overnight. Lures for the two species showed no significant loss in attractiveness after 8 weeks in the field, and chemical analysis showed 19% of the C. puncticollis pheromone and 72% of the C. brunneus pheromone remaining after this time. Summarizing, the following trap is presently recommended for monitoring/controlling African Cylas species: a 5-l plastic jerry can trap of any colour with rectangular openings of 11×5 and 6×5 cm positioned 15 cm above the crop canopy, filled with 0.5 l Omo solution (1 g/1 l water), with 0.1 mg lures to be replaced every 8 weeks.

    Flight activity ofProstephanus truncatus (Horn) (Coleoptera: Bostrichidae) in relation to population density, resource quality, age, and sex (1996)

    Notes: Abstract Higher flight activity has been observed in aged, high-density cultures ofProstephanus truncatus (Horn) (Coleoptera: Bostrichidae), but adults in new, lowdensity culture jars showed less flight activity. In order to understand this change in behavior, the effects of population density, age, resource quality, and sex on the flight ofP. truncatus were studied in a wind tunnel. While an immediate density on the release platform had no significant effect on flight, beetles from high-density cultures were more inclined to fly than those from low-density cultures. Resource quality exerted a major influence on flight; insects in food suitable for boring and oviposition seldomly exhibited flight, however, when food was absent or of inferior quality for boring and oviposition, the dominant behavior was flight. Also, insects maintained for a week in food suitable for boring and oviposition were less ready to fly than those maintained in food unsuitable for boring and oviposition. The optimum age range for flight activity was before the peak of reproduction and insects rarely flew before 4 days or after 32 days of emergence. There were no significant differences between the flight activity of males and that of females. Based on these results, we conclude that age and resource quality are major influences on the flight activity ofP. truncatus and a hypothesis is proposed in which reproductively active male and female beetles disperse from habitats of low resource quality to those that support their reproductive behavior. The practical implications of these results and the possible role of the male-produced aggregation pheromone are discussed.

    Notes: Abstract The frass of the pyrgo beetle (Paropsisterna tigrina) feeding on commercial plantations of the terpinen-4-ol chemical variety of the Australian tea tree.Melaleuca alternifolia, was found to contain a volatile oil almost identical to the essential oil of the ingested leaf. When beetles were fed leaf containing substantial quantities of 1,8-cineole, the predominant frass metabolite as determined by MS, IR,13C and1H NMR, GC, and CoGC was (+)-2β-hydroxycineole. Both male and female adults and larvae metabolizedMelaleuca oils in similar ways.

    Notes: Abstract Adult Sitona lineatus L., (Coleoptera: Curculionidae) feed on the leaves of various species of leguminous plants, and females lay in the vicinity of pea plants, the roots of which are eaten by the larvae. A study of the volatiles from several legumes and of the response of S. lineatus individuals to these substances was undertaken using two complementary techniques: behavioral, to study the locomotory orientation; and electrophysiological, using electroantennography (EAG). Four volatile compounds, cis-3-hexen-1-ol, 2-hexenal, cis-3-hexen-1-yl acetate, and 3-octanone, were identified from pea, vetch, clover, and lucerne, by coupled gas chromatography–mass spectrometry (GC-MS) and coupled gas chromatography–infrared spectrometry (GC-IR). After emergence from July to mid-November, the imago display high response to the odor of pea and some other leguminous plants. A second period of enhanced sensitivity was observed during crop colonization from March to May. High EAG response to pea odor and cis-3-hexen-1-yl acetate was correlated with periods of enhanced locomotory orientation during these months. Experimental results indicate that cis-3-hexen-1-yl acetate could play a key role in discriminating pea among other acceptable leguminous species.

    Notes: Abstract Stationary water traps were used to sample the aquatic invertebrates from both shallow, drought-sensitive pools and deeper, more permanent pools on blanket bog in the Flow Country, northern Scotland during 1994–1995, an area important for nature conservation. The differences in numbers of invertebrates trapped, and the differences in species composition and abundance of adult aquatic Coleoptera and Hemiptera (the two most abundant groups caught) between these two pool types, and spatially within the deeper pools, were investigated. Using the same trapping effort, seven times more invertebrates and five times more adult Coleoptera were taken in the deep (A4) pools compared to the shallow (A3) pools, and Hemiptera were almost exclusively trapped in the A4 pools (only 2% of the catch was from A3 pools). DECORANA showed that the Coleoptera species composition of the two pool types was different, although a small overlap existed, presumably because of the proximity of the pool types and of the continuous nature of the variation between them. There was little difference in the numbers taken or species composition of Coleoptera or Hemiptera from the edges or centre of the A4 pools. Smaller Coleoptera species were found in both pool types, although one species was more common in the centre of the larger pools. Larger Coleoptera with a body length of more than 11.6 mm were not found in the A3 pools, only in the deeper A4 type. The A4 pools were found to be more stable seasonally than the shallow pools with respect to invertebrate numbers trapped, and this may be linked to the chance of drying out of the latter in dry periods. The influence of pool stability (through water level) on invertebrate abundance, development and individual species size is discussed, as is the sampling method used, the significance of the peatland fauna and its importance to breeding bird life associated with peatland pool complexes.
