The present study discusses the light trapping of harmful insects depending on the moonlight, its polarized percentage, and the moon phases. The trapping data were taken from light traps of North Carolina and Nebraska States of USA. We examined five species. The maximum individual number of species was collected at new moon or near the first quarter and last quarter. The farmers can use our results to forecast their plant protecting works.

AbstractThe biting activity of Culex (Melanoconion) portesi Senevet & Abonnenc and C. (M.) taeniopus D. & K. in a secondary seasonal marsh forest in Trinidad was studied by means of catches by six mouse-baited suction traps, and a single light-trap. The traps were cleared at hourly intervals between 17.00 h and 07.00 h on nights which approximated to the new, first quarter, full and last quarter phases of the moon. The catches were compared with illumination at canopy and ground level which was estimated by selenium photocells whose output was recorded on the continuous chart of a servo-potentiometer. Humidity, rainfall, temperature and cloud cover were also recorded. In the suction traps both species showed peaks of activity at evening and dawn twilight at new moon, although the dawn peak was not very pronounced with C. taeniopus, but this pattern was modified on other nights in a manner which was consistent with moon age. At full moon the evening and dawn peaks were replaced by increased activity during moonrise and the middle of the night. The light-traps failed to show the evening and dawn activity and did not always duplicate the baited traps during darkness. Two hypotheses based on either a permissive range of illumination or an underlying circadian rhythm are discussed; neither fully explains the observed biting activity. Although an association between moonlight and biting activity does exist, an understanding of its nature will require more experimental data.

AbstractAn account is presented of the distribution and amounts of moonlight in latitudes near the equator. This includes a Table on the amount of moonlight for each hour of the night throughout a standard lunar cycle, applicable to any locality between 10°N and 10°S, and a Table of standard groups of moon phase which can be used at any locality irrespective of latitude. The construction of these Tables is described in detail and their use briefly discussed. A method is described which enables light-trap catch records to be arranged for analysis directly against moon phase.

AbstractThis study is on the light trapping of caddisfly species (Insecta: Trichoptera) related to the proportion of males and females and the moon phases. The data collected includes 24 species in 9 light-trap stations, for 49 swarming events between the years 1980 and 2000. We found the massive emergence of adults happens fractionally in swarming intervals. This is connected with the phenology and life cycle of each species. The percentage of males and females of the same species during different swarming events cannot be considered equal. The proportion of males and females are different in the swarming of different species. We found that the number of male and female individuals is substantially synchronized with each other within the swarming, but it can be different in the case of each species. The duration of the swarming, even in the same species, are not always uniform. The effect of the Moon cannot be clearly identified in any species, even if data from several swarmings are available. The swarming peaks appear near different Moon quarters.


This will be discussed later. Two species, Mansonia uniformis and Mansonia septempunctata, which breed in association with macrophytes such as water hyacinth Eichhornia crassipes, became less common from stage 1 to 2. The saltmarsh species Aedes vigilax was also collected in reasonable numbers at all localities around the reservoir. This species is known for its wide dispersal powers and was undoubtedly blown in from the extensive intertidal wetlands on the coast. Thus on the basis of abundance, two taxa – Culex annulirostris and Anopheles annulipes s.1. – warranted further consideration. The former species is considered to be the major vector of arboviruses in Australia (Russell 1995), transmitting Ross River, Barmah Forest, Kunjin, Kokobera, Alfuy and Edge Hill viruses and Murray Valley encephalitis, as well as dog heartworm. Of these, Ross River is by far the most common arbovirus in coastal northern Queensland, with morbidity approximating 400 cases per 100,000 population. Thus from first principles, this arbovirus and perhaps Barmah Forest, about which little is known, would constitute the greatest hazard to recreational use. Although Anopheles annulipes has previously been implicated in malaria transmission at Sellheim during the Second World War, this species group has returned isolated positives of Ross River and Barmah Forest viruses and Murray Valley encephalitis from other parts of Australia. However, no transmission studies have been done on the population from the reservoir. Thus on the evidence to date, it could not be regarded as a major concern at the Ross River dam. Both Culex annulirostris and Anopheles annulipes were shown to have seasonal peaks of abundance during the late post-wet season (March to May), with populations building up with the onset of spring (September to October). Spatially, the trapping programme was designed to compare mosquito numbers on the foreshore of the stage 1 lake with two localities expected to be on the margins of the stage 2A lake, with two remote localities (and therefore theoretically unaffected by any water resource project activity) as negative controls. Mosquito numbers (i.e. for those species known to breed at the dam) decreased with distance away from the Ross River dam. Both light trapping and human bait collections carried out twice per month were reasonable indicators of broad seasonal trends in mosquito abundance. However, the statistical analysis indicated that occasionally the light traps could miss short periods of high biting activity (Jones et al. 1991). If greater resolution was required, it was recommended that light traps could be supplemented with animal baited traps, although it is probable that this could be rectified by intensifying the light trapping regimen. Cluster analyses of dam breeding species in both 1984–85 and 1991–93 indicated that light trap catches along the northern (Big Bay, Ti-Tree Bay, Round Island) and western sides (Ross River) gave similar patterns, but the profile towards the east (Antill Creek, Toonpan, Oak Valley) was somewhat different (Barker-Hudson et al. 1993; Hearnden and Kay 1995). On this basis, adult mosquito surveillance would therefore need to be based on two localities at either end of the lake.

Activity of Microtus pennsylvanicus was recorded as the number of crossings per day over a sand transect during four consecutive summers. Appropriate samples were selected to test the effects of both moon phases and moonlight on activity. Initially the results of tests comparing new moon to full moon phases showed that the voles were more active during new moon in only 3 of 10 discreet paired samples tested. However, when the effects of sampling sequence, phenology of population growth, date at which moon phases occurred, and, finally, the effect of climate were all considered as factors which could have affected the above results, it seemed reasonable to conclude that the new moon phase tended to be associated with higher activity. To establish if moonlight by itself, independent of phases, was a factor affecting the activity, tests were made during brightest and darkest nights of the lunar month and results indicated that moonlight did not affect the differences in activity found in the moon phase tests.

Trapping programs for mammals often have low capture success, which is known to be influenced by a range of environmental factors, in addition to aspects of the traps themselves. However, the behavioural responses to traps by the target species are largely unknown. We simultaneously set camera traps and soft-walled double-layered traps for swamp wallabies, Wallabia bicolor, and used images from the camera traps to investigate responses by the target species. Wallabies mostly visited traps after sunset, with the number of visits declining steadily through the night. Visits to traps were more frequent during crescent and new moon phases and when the moon was set. In the majority (59%) of these visits, wallabies did not enter the traps. In some cases wallabies consumed only the bait outside the trap, or the trap door had been closed, usually by other swamp wallabies or bobucks, Trichosurus cunninghami, but in many cases (28% of visits) we could not discern why wallabies failed to enter. When wallabies did enter traps, just 14% of visits resulted in successful capture, with non-captures mainly occurring because wallabies reached in to obtain bait without triggering the trap.

La observación de las fases lunares para realizar actividades agrícolas, es una costumbre de muchas culturas alrededor del mundo. Sin embargo, existen pocos estudios científicos relacionados con este tema. El objeto de esta investigación fue determinar la influencia de las fases lunares sobre el rendimiento del maíz. Para ello se consultó a 45 productores de 19 comunidades de la Región Autónoma Atlántico Sur (RAAS), sobre el uso de las fases lunares para la siembra. Además, se estableció un experimento utilizando un diseño de bloques completamente al azar con cuatro repeticiones por cada fase lunar (16 parcelas en total). Se midió el porcentaje de germinación, el crecimiento y rendimiento del cultivo. Los datos fueron analizados utilizando el programa InfoStat versión 2010. Los resultados reflejan que la germinación de las semillas presentó diferencias estadísticas significativas, siendo mayores en parcelas sembradas en las fases de cuarto creciente y luna nueva. La variable altura, largo y peso de mazorca, no presentaron diferencias significativas según fase lunar. En la variable diámetro del tallo se encontró diferencia significativa; las plantas sembradas en luna nueva presentaron el mayor diámetro. El daño causado por enfermedades y herbívoros presentó un resultado variable para las cuatro fases lunares. El peso promedio del maíz sembrado en la fase de luna nueva fue mayor que en las otras fases, contrario a la creencia popular de los productores de la región. SUMMARY Observation of the moon phases for agricultural activities is a custom in many cultures around the world. However, there are few scientific studies related to this topic. The purpose of this research was to determine the influence of moon phases on corn yields. In order to achieve this goal, 45 producers were consulted from 19 communities in the South Atlantic Autonomous Region (RAAS), regarding the use of the moon phases for sowing. Besides, an experiment was made using a block design completely at random using four replicates for each moon phase (16 plots in total). We measured the percentage of germination, the growth and yield of the crop. Data were analyzed using InfoStat 2010 version. The results show that the seed germination presented significant statistical differences, being higher in plots planted in the first quarter and new moon phases. The variables such as height, length and cob weight, showed no significant differences according to the moon phase. Regarding the stem diameter, significant differences were found, in which the plants sowed on new moon had the biggest diameter. The damage caused by diseases and herbivores presented an outcome variable for the four moon phases. The average weight of corn sowed in the new moon phase was higher than in the other phases, contrary to the producer’s popular belief in the region.

Field sampling was conducted from July to August 2019 to determine the diversity and abundance of beetle fauna at Gayo Lues Forest, Takengon, Central Aceh. The study was conducted at two sites namely trail I and trail II. The beetles were sampled using 2 light traps, 2 malaise traps and 20 pitfall traps. Total of 219 beetle specimens comprising of 67 species from 24 families were collected. Light trap collected the most number of beetles (N=117) and Margalef index showed that the most abundant beetle was collected by light trap (Margalef index, 27.551). Shannon-Weiner index shows that the most specious beetle was caught by light traps (4.399). The results showed that the most efficient trap was light trapping. Trail I has the most abundance (Margalef Index: 18.572) but trail II was the most specious (Shannon Weiner Index: 4.176) beetle fauna, whereas trail II has the least abundance (Margalef Index: 17.295) and Campsite has least diverse (Shannon Weiner Index: 3.769).The most abundant family caught was Staphylinidae (Margalef index : 2.667) and specious beetle family caught was the Chrysomelida (Shannon Weiner : 1.846) followed by the ground beetle family Scarabaeidae  (Shannon Weiver:1.828). Result of this findings showed that Gayo Lues Forest is an undisturbed forests and has been preserved well.Keywords :  Beetle, Diversity, Abundance, Takengon, Gayo
