Rearing Methods

The present research was carried out to document the moth fauna of Annamalai Nagar during December, 2015 to November, 2016 comprising four seasons for a period of one year, from agriculture and horticulture ecosystems using light traps and host rearing methods. The sheet method was used to record moth insects individually without any damage. Any moths that alight on the screen were recorded in jars just after sunset between 18.00 – 23.00 hr. A total of 2,679 moths were recorded using all the three types of methods employed in the study. Out of which, light trap was found with maximum of 2,253 moths followed by manual collection (369) and host rearing (57) from four different sites of observation. Among the sites, light trapping of moths were observed maximum (656) in Orchard followed by Experimental farm with 629 numbers. The diversity of moths was observed in the study area of Annamalai Nagar indicated the presence of 70 genera and 56 species identified under nine superfamilies of Clades viz., Obtectomera (Pyraloidea and Thyridoidea) Macroheterocera (Noctuoidea, Bombycoidea, Geometroidea, Lasiocampoidea) Apoditrysia (Pterophoroidea and Cossoidea) Ditrysia (Tineoidea). The families namely Crambidae, Erebidae, Noctuidae, Sphingidae, Bombycidae, Uraniidae, Thyrididae, Eupterotidae, Geometridae, Pterophoridae, Lasiocampidae, Cossidae and Psychidae were observed in the study area. Out of which, the family Erebidae alone had 28 genera and 25 species and found to be the superior family. From the results, it was clear that light trapping was superior in collection of moths during night times.

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.

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

The Tropics

For many years amateur entomologists have considered that on nights of full moon it is of little use going out to catch specimens, as insects will be few in number. This belief applies to all methods of collecting, including bait (sugaring) and light, and is supposed to apply particularly to the Lepidoptera. Scattered through the literature on Agricultural Entomology one finds occasionally references to the use of light traps for the destruction of pests, and statements, usually from the tropics, that the catches were less at times of full moon ; but so far as I am aware no proper statistical study of the question has ever been made. One of the most striking series of figures is that produced by Pagden (1932) by trapping with a light trap the two Pyralid moths Diatraea auricilia and Schoenobius incertellus which are pests of rice in Malaya. He found, between 18 January and 29 June, 1931, six periods of maximum catch in both sexes of both species corresponding more or less to the no moon periods, and six periods of minimum catch corresponding even more definitely to the full moons. Scarcely any insects were captured at the time of full moon.

Trapping Trials

Abstract West Nile virus (WNV) is the most prevalent arbovirus found throughout the United States. Surveillance of surface breeding Culex vectors involved in WNV transmission is primarily conducted using CDC Gravid traps. However, anecdotal claims from mosquito abatement districts in Louisiana assert that other trap types may be more suited to WNV surveillance. To test the validity of these assertions, we conducted a series of trapping trials and WNV surveillance over 3 yr to compare the efficacy of multiple trap types. First, we compared the CDC Gravid trap, CO2-baited New Standard Miniature Blacklight traps, and CO2-baited CDC light traps with either an incandescent light, a red light, or no light. We found that the CDC Gravid trap and CO2-baited no-light CDC Light trap collected the most mosquitoes. Second, we conducted additional, long-term trapping and WNV surveillance to compare these two trap types. We found that CO2-baited no-light CDC traps collected more of the local WNV vector, Culex quinquefasciatus (Say, Diptera, Culicidae), and detected WNV with greater sensitivity. Finally, we conducted trapping to compare the physiological states of Cx. quinquefasciatus and diversity of collected mosquitoes. CO2-baited no-light CDC light traps collected more unfed Cx. quinquefasciatus while Gravid traps collected more blooded Cx. quinquefasciatus; both traps collected the same number of gravid Cx. quinquefasciatus. Additionally, we found that CO2-baited no-light CDC light traps collected a larger diversity of mosquito species than Gravid traps.

Questionnaires were presented to 73 psychiatric ex-patients to determine their retrospective attitudes toward participation in a one-year study of post-hospital adjustment. More than 50% of Ss reported that research contacts had been helpful in one or more specific respects. Attitudes toward research demands were predominantly neutral. Patients who completed 6 or more monthly interview-test sessions ( N = 53) differed from those who completed 5 or less ( N = 20) in finding research contacts more helpful, questions easier to answer and enlightening vs confusing, and study participation conducive to cohesion vs disruption in the family. Dropouts appeared to have in common wishes to deny mental illness and to forget hospitalization.

Emigration by skilled and semi-skilled workers from India to the Middle East is a strategy for better economic returns. Families rarely accompany migrants. Drawing insights from primary data gathered from intensive fieldwork in Sivaganga district, Tamil Nadu, this article attempts to understand the psychological consequences on the wives left behind. A mixed sampling method was used to derive the sample size. Analysis of variance (ANOVA) and Pearson’s chi-square tests were mainly used for quantitative analysis supplemented by qualitative methods. The results indicated that wives considered loneliness the most significant psychological problem arising from their husbands’ absence. Stress was also caused by financial problems and the necessity of taking on additional roles in the family.

The article presents the results of research of the using light traps (luminescent lamp Actinic 6W) for collecting Coleoptera in the Saratov city. Entomological material was collected by the second author in the period from 1.06 to 2.10.2019. In 2019, 52 species of Coleoptera of 22 families from different ecological groups were recorded. A relatively high proportion of adventitious species remains in 17.3– 30.7% of the presented fauna was presented. For two years the 14 species of alien and cryptogenic Coleoptera species were observed, that is 24.5% of the adventive fauna of the Saratov Province. Among invasive species Attagenus smirnovi, Stegobium paniceum, Atomaria lewisi, Harmonia axyridis, Gnatocerus cornutus, and Orchestes steppensis were record for the first time in 2019. It to use bringing on light as one of the available and low-cost ways to identify alien and cryptogenic organisms in urban areas is recommended.
