Sex attractants have recently been reported for several species of Elateridae: Hypolithus bicolor Esch. (Doane 1961); Hemicrepidius morio (LeConte) (Chapman 1964) ; and Limonius californicus (Mann.), Agriotes ferrugineipennis (LeConte), Ctenicera sylvatica (Van Dyke), and C. destructor (Brown) (Lilly and McGinnis 1965). Lilly (1959) demonstrated the attractiveness to males of ethyl alcohol extracts from virgin females of the sugar-beet wireworm (L. Californicus). The attractants appear to be species-specific (Lilly and McGinnis 1965).

AbstractTests of intertrap variability in catches of moths of the darksided and redbacked cutworms, Euxoa messoria (Harris) and E. ochrogaster (Guenée), were conducted by placing two traps for each species baited with synthetic sex attractants at 1.6 km (1 mi) intervals to form a grid covering 64 km2 (25 mi2) near Domain, Manitoba. These sex attractants were 93 and 99.6% species specific for E. messoria and E. ochrogaster respectively. Moth catches varied between traps and flights, but the ranking of the traps by catch for each species was consistent during any given flight period. Variability in intertrap catches of E. messoria indicated the moths were not evenly distributed throughout the test area and consequently a sex-attractant trap system with 1.6 km trap spacing is not suitable for monitoring population levels. For E. ochrogaster four traps within an area of 64 km2 would be required to give a population estimate within 20% of the true mean. The flights of E. messoria are not related to degree days and started abruptly and at the same time each year suggesting that development may be synchronized by the summer diapause of the prepupae. The flights of E. ochrogaster were related to degree day accumulations above a threshold temperature of 12.5 °C. Crops had no apparent influence on the distribution of moth catches for either species.

AbstractIntertrap variability in catches of moths of the cutworms Leucania commoides Guenée and Peridroma saucia (Hübner) was tested by placing two traps for each species baited with artificial sex attractants at 1.6 km (1 mi) intervals to form a grid covering 64 km2 (25 mi2) near Domain, Manitoba. During the flight periods of the test species the attractants were 86.5 and 93.6% species-specific for L. commoides and P. saucia respectively. Moth catches varied between traps and flights, but the ranking of the traps by catch for each species was consistent during any given flight of L. commoides and during the first flight of P. saucia. The low intertrap variability in numbers captured of both species indicated the moths were uniformly distributed in the area. For L. commoides 10 traps within an area of 64 km2 would be required to give a population estimate within 20% of the true mean and for P. saucia three traps would be needed. The flights of L. commoides started abruptly each year and appeared to be triggered by rainfall. Flights of P. saucia did not occur below 10 °C but otherwise weather had no apparent influence on the flights. It was concluded that the moths of this species are blown in from the south each spring. Neither species showed a consistent distributional relationship with crops.

The white cutworm, Euxoa scandens (Riley), is a sporadic pest of tobacco in Quebec (Mailloux and Desrosiers 1978), asparagus in Michigan (A. L. Wells, pers. comm.), and other vegetable crops grown in light sandy soils (Beirne 1971). The immature larvae overwinter and cause serious damage when they resume feeding in the spring (Hudson and Wood 1930). Moths emerge and oviposit from late June until late July (McLeod and Dupré 1981). An efficient monitoring method utilizing the female sex pheromone would be an important aid in estimating the size and distribution of the adult population and would help in planning insecticide control. We report here some results of electroantennogram screening of potential sex attractants and the results of field tests of the most active of these.

1. Photomicrographs of crystals of pure carbonmonoxide hemoglobin of the following species are presented; ox, sheep, hog, dog, turkey, rat, horse, chicken and guinea pig. Photomicrographs of the oxyhemoglobin crystals of the following species are also shown: ox, sheep, hog, dog, rat, horse and guinea pig. The crystals were formed from the pure protein by adding a suitable amount of ethyl alcohol and maintaining a temperature of 0°C., or lower. 2. In some species a sufficient difference is shown between the carbonmonoxide hemoglobin and oxyhemoglobin crystals to distinguish these compounds, but the photographs of crystals of carbonmonoxide hemoglobin and oxyhemoglobin of some species, such as guinea pig, show no appreciable difference. 3. Differences between the carbonmonoxide hemoglobins, as well as between the oxyhemoglobins, of the different species studied are indicated. 4. The carbonmonoxide hemoglobin crystals from the bloods studied are species specific in their nature, and, in many cases, can be distinguished from the analogous oxyhemoglobin by crystallographic study.

Abstract Species-specific behavior-modifying chemicals have been used for more than 50 years for monitoring and management of insect pests of agriculture and human health. Elaterid beetle larvae are among insect pests in soil that are increasingly problematic, in part due to the lack of effective management strategies. However, little is known about the insect-produced chemicals that mediate the reproductive behavior of these pests. We used chemical and behavioral studies to identify, synthesize, and field test the sex attractant pheromone of adults of Melanotus communis, commonly called the corn wireworm, the larvae of which are economically important pests of U.S. crops. Our results indicated that a single female-produced chemical, 13-tetradecenyl acetate, was strongly attractive to conspecific male beetles, and did not appear to attract other species. In field evaluations, male M. communis exhibited a dose-dependent response to this compound. In a trial comparing different slow-release dispensers, a small rubber septum impregnated with the chemical was as effective as and easier to use than a plastic bag dispenser. Given that the sex attractant of this insect consists of a single compound that can be readily synthesized, its development for monitoring and management of the corn wireworm may be economically feasible.

Agriotes Lineatus

AbstractElaterids of the species Agriotes lineatus (L.), which were collected in heap-traps (at Stenum, Skara, West Sweden) during the period May 9-24, I972, were sorted according to sex. The abdomens of the males and females respectively were crushed in 95 % ethyl alcohol for the extraction of possible pheromones. The unfiltered fluid was tested in pitfall traps placed in a field of oats. During the period May II - July 3, I70 A. lineartus were obtained of which I62 were males. The majority of these were caught in the traps baited with female extract. The male extract caused no response. The female extract must therefore have contained a sex pheromone which attracted males of the same species.
