A study on diversity and abundance of insects in rice field was conducted at farmer field of Lamahi, Dang during July to October in 2019. Insects were collected using sweep net and light trap. Overall, 414 insect specimen representing 11 families and 8 orders were collected during the period. Grasshopper (23.98%) with including all species was the most abundance insect found in rice field as it followed by brown plant hopper (16.62%). Among the eight insect orders captured Orthoptera (29.16%) was the most abundance insect order followed by Homoptera (16.62%). As the diversity of insect pest in this area may responsible economic losses was found which will be useful to adapt appropriate management practices to keep them at normal area. The presence of natural enemies should conserve to enhance the natural biological control of insect pests.

AbstractThe efficiency of miniature CDC light-traps in catching West African malaria vectors was evaluated during two rainy seasons in a village near Ouagadougou, Burkina Faso. Traps were employed both indoors and outdoors using human baits protected by an insecticide-free mosquito-net and different sources of light. Indoors, light from incandescent bulbs increased the catch of Anopheles gambiae s.l. (mainly A. arabiensis Patton and the Mopti chromosomal form of A. gambiae s.s. Giles) and A. funestus Giles c. 2.5 times as compared to traps whose light bulb was removed. Conversely, the difference was not significant when a UV ‘Blacklight-blue’ fluorescent tube was compared to the incandescent bulb. Protecting the bait with a mosquito-net increased the catch c. 3 times for A. gambiae s.l. and c. 3.5 times for A. funestus. A prototype model of double bednet gave intermediate yields. Outdoors, the addition of incandescent bulbs to unlighted traps did not significantly increase the number of vectors caught, but the addition of the mosquito-net to the unprotected human bait did so by c. 1.5–4 times. Thus, the CDC light-trap hung close to a human sleeping under a bednet and fitted with an incandescent bulb, was considered the most practical and efficient in terms of numbers of vectors caught, consequently its indoor efficiency was compared to human landing catches on single collectors and estimated to be 1.08 times and density-independent. Outdoor light-trap catches were either not significantly correlated to biting collections (as for A. gambiae s.l.), or density-dependent in their efficiency (as for A. funestus); thus, they were not considered a reliable means for estimating malaria vector outdoor biting densities in this area. No difference was found in the parous rate of A. gambiae s.l. samples obtained with CDC light-traps and human landing collections.

Abstract Background Vector surveillance is essential in determining the geographical distribution of mosquito vectors and understanding the dynamics of malaria transmission. With the elimination of human malaria cases, knowlesi malaria cases in humans are increasing in Malaysia. This necessitates intensive vector studies using safer trapping methods which are both field efficient and able to attract the local vector populations. Thus, this study evaluated the potential of Mosquito Magnet as a collection tool for Anopheles mosquito vectors of simian malaria along with other known collection methods. Methods A randomized 4 × 4 Latin square designed experiment was conducted to compare the efficiency of the Mosquito Magnet against three other common trapping methods: human landing catch (HLC), CDC light trap and human baited trap (HBT). The experiment was conducted over six replicates where sampling within each replicate was carried out for 4 consecutive nights. An additional 4 nights of sampling was used to further evaluate the Mosquito Magnet against the “gold standard” HLC. The abundance of Anopheles sampled by different methods was compared and evaluated with focus on the Anopheles from the Leucosphyrus group, the vectors of knowlesi malaria. Results The Latin square designed experiment showed HLC caught the greatest number of Anopheles mosquitoes (n = 321) compared to the HBT (n = 87), Mosquito Magnet (n = 58) and CDC light trap (n = 13). The GLMM analysis showed that the HLC method caught significantly more Anopheles mosquitoes compared to Mosquito Magnet (P = 0.049). However, there was no significant difference in mean nightly catch of Anopheles mosquitoes between Mosquito Magnet and the other two trapping methods, HBT (P = 0.646) and CDC light traps (P = 0.197). The mean nightly catch for both An. introlatus (9.33 ± 4.341) and An. cracens (4.00 ± 2.273) caught using HLC was higher than that of Mosquito Magnet, though the differences were not statistically significant (P > 0.05). This is in contrast to the mean nightly catch of An. sinensis (15.75 ± 5.640) and An. maculatus (15.78 ± 3.479) where HLC showed significantly more mosquito catches compared to Mosquito Magnet (P < 0.05). Conclusions Mosquito Magnet has a promising ability to catch An. introlatus and An. cracens, the important vectors of knowlesi and other simian malarias in Peninsular Malaysia. The ability of Mosquito Magnet to catch some of the Anopheles mosquito species is comparable to HLC and makes it an ethical and safer alternative. Graphic Abstract

A descriptive cross-sectional questionnaire survey on Japanese encephalitis was conducted in Bhaktapur district. Mosquitoes were collected for six months by means of dark activated rechargeable CDC light trap. Out of 884 mosquitoe individuals collected, 73.41 percent were Culex species. The highest numbers of mosquitoes were collected in July and August. There was no significant variation in Culex vectors abundance during six months in three study sites Tathali, Bode and Bhelukhel. Significant correlation was found between level of knowledge and attitude towards JE prevention. Fair level of practice towards JE prevention but having no good attitude shows that though people are supportive towards JE control.  Journal of Institute of Science and Technology, 2015, 20(1): 112-118

Mosquito transmitted diseases are still a health problem in Indonesia, including in Palu City. Among the types of mosquitoes as a vector of the disease, there are to be zoophilic of animal blood. The study against the diversity of mosquitoes has been conducted in the area with the largest cattle population in Palu City, that Mantikulore District. The purpose of this study was to gain an overview diversity of mosquitoes around the cattle sheds. The study was carried out with free collection of mosquitoes around cattle sheds from 18:00 to 06:00 and one light trapping (CDC-Light Trap) at each location throughout the night from 18:00 to 06:00. Distribution diversity of mosquito around cattle sheds in five locations obtained 3 genus and 14 species of mosquitoes from a total of 1,464 captured mosquitoes. Culex vishnui is the most abundant mosquito in four research sites, namely in Kawatuna (44.44%), Poboya (82.18%), Tondo (66.95%), and Tanamodindi (38.58%). While in Talise the most abundant mosquito is Cx. quinquefasciatus amount 52.39%. The abundance of Cx. quinquefasciatus and Cx. vishnui was directly proportional to the frequency and dominance index. Shannon-Wiener diversity index shows the level of diversity in Kawatuna village, Talise village, and Tanamodindi village belongs to the medium, and in Poboya village and Tondo village belongs to low.

Chaiphongpachara T, Laojun S, Kunphichayadecha C. 2018. Effect of the CDC light trap on control of nocturnal mosquitoesin coastal Samut Songkhram Province, Thailand. Biodiversitas 19: 1750-1754. This study aimed to investigate the effect of CDC lighttrap on mosquito control and to study the relationship between this effect and weather factors in coastal areas (2 and 4 km from the sea)of Samut Songkhram Province, Thailand. We conducted a field test by trapping for 30 consecutive days from September to October2017. The trap was hung at a height of 1.5 m and was 50 m away from a house. A total of 2963 adult female mosquitoes of 4 speciesbelonging to 2 genera were trapped, including Anopheles epiroticus Linton & Harbach, Culex quinquefasciatus Say, Cx. sitiensWiedmann and Cx. gelidus Theobald. The trapping rate of the CDC light trap set up 2 km from the sea was 85.70±73.81 adultmosquitoes per night. Meanwhile, at the location 4 km from the sea, the trap collected 13.07±11.40 adult mosquitoes per night.Comparing the numbers of mosquitoes captured by the CDC light trap between these two sites, there was a significant difference at p <0.05. This study shows that the CDC light trap can be used for effective control of mosquitoes in coastal areas of Samut SongkhramProvince, Thailand, especially Cx. sitiens, a filariasis vector.
