“…These results were different from the findings of others researchers (Brower, 1975;Burkholder, 1990;Wileyto et al, 1994;and Pierce, 1994). Brower (1975) reported that for aggregation pheromones that attract females, mass-trapping may have significant impact on a population if substantial females are removed.…”

An experiment on the efficacy of pheromone on capturing angoumois grain moth, Sitotroga cerealella (Olivier) was conducted in the laboratory of the Department of Entomology, Sher-e-Bangla Agricultural University, Bangladesh, using rice variety BR11. Pheromone (X-lure) trap was used as a treatment and data were recorded at different days and distances. The experiment was laid out in a Completely Randomized Design (CRD) with four replications. In case of total captured moth, the highest percentage (%) was recorded at 1 st day (28.60%), whereas the lowest percentage (%) was recorded at 15 th day (7.60%). It was also observed that with the increase of distance of pheromone trap, the % of captured moth was decreased. The pheromone X-lure was found useful only for monitoring S. cerealella (Olivier).

“…[12], [13]), and pest control (e.g. [14], [15]). Methodologically, these experiments differ on important aspects, including the amount of (experimental and statistical) control exerted, the temporal and spatial scale of measurement, subtleties of design and analysis, and the response measure used to quantify reproductive success.…”

Female Fertilization: Effects of Sex-Specific Density and Sex Ratio Determined Experimentally for Colorado Potato Beetles and Drosophila Fruit Flies

et al. 2013

If males and females affect reproduction differentially, understanding and predicting sexual reproduction requires specification of response surfaces, that is, two-dimensional functions that relate reproduction to the (numeric) densities of both sexes. Aiming at rigorous measurement of female per capita fertilization response surfaces, we conducted a multifactorial experiment and reanalyzed an extensive data set. In our experiment, we varied the density of male and female Leptinotarsa decemlineata (Colorado potato beetles) by placing different numbers of the two sexes on enclosed Solanum tuberosum (potato plants) to determine the proportion of females fertilized after 3 or 22 hours. In the reanalysis, we investigated how the short-term fertilization probability of three Drosophila strains (melanogaster ebony, m. sepia, and simulans) depended on adult sex ratio (proportion of males) and total density. The fertilization probability of female Leptinotarsa decemlineata increased logistically with male density, but not with female density. These effects were robust to trial duration. The fertilization probability of female Drosophila increased logistically with both sex ratio and total density. Treatment effects interacted in m. sepia, and simulans. These findings highlight the importance of well-designed, multifactorial experiments and strengthen previous experimental evidence for the relevance of sex-specific densities to understanding and prediction of female fertilization probability.

“…Hence, suppression of male moths at high densities with attracticide may have only limited effect on the total population because remaining males tend to compensate by increasing their number of matings (Brower 1975). We found that when the moth density is one moth pair per 11.3 m 3 , signiÞcantly fewer eggs were laid in the simulated storage sheds with a freely exposed attracticide gel dot compared with the oviposition in storage sheds with a caged dot of attracticide or control (untreated) storage sheds.…”

Plodia interpunctella (Hübner) is a serious and widespread postharvest pest on cereal products, dried fruits, candy, and pet food. Due to the strong positive anemotactic flight response of P. interpunctella males to the main component of the female-produced pheromone [(Z,E)-9,12-tetradecadienyl acetate, herein referred to as ZETA], we evaluated the potential of an attracticide for this pest, in which ZETA as attractant was combined with permethrin as the killing agent. Two concentrations of ZETA [0.16 and 0.32% (wt:wt)] and five concentrations of permethrin [0, 3, 6, 12, and 18% (wt:wt)] were incorporated into Last Call gel (10 different permethrin:ZETA combinations). All attracticide gels were evaluated in a toxicity test, in which either the tip of a leg or an antenna of a virgin P. interpunctella male was touched < 3 s into a dot of attracticide gel. These males were subsequently transferred to jars with virgin females. The toxicity test showed that a brief and gentle contact of P. interpunctella males with attracticide gel containing 3-18% permethrin caused a significant reduction in mating and killed males moths within 24 h. A wind tunnel test was conducted to evaluate the flight responses of P. interpunctella males to the same 10 attracticide gels. Male moths displayed significantly higher levels of positive anemotactic flight and more males made contact with the attracticide gel when the ZETA concentration was 0.16% compared with 0.32%. P. interpunctella males showed no signs of repellency to permethrin concentrations within a range of 0-18% in the attracticide gel. Three densities of P. interpunctella pairs were released into small warehouse rooms, and we found that the attracticide gel suppressed oviposition when the moth density was at a low level, but it was ineffective when the moth density exceeded one male-female pair per 11.3 m3.
