The biting midge fauna of Dongzhaigang Mangrove Forest, Hainan Province, China was sampled on 14 October 2015 using three methods: a pan light trap operated from dusk until dawn the following morning and sweep net and human landing collections performed between 16:15–17:15 hr. Eight species, including two new records for China, Culicoides palawanensis and C. niphanae, and one new record for Hainan, C. circumbasalis, were collected. A key to assist with identification of specimens of these species is provided. DNA barcodes supported the morphological identification of some of these species and identified the potential presence of cryptic species and/or deep population structure in others. The newly recorded species were morphologically similar to species previously reported from Hainan, highlighting the need for further investigation into the taxonomy of biting midges in this region. Species composition and abundance varied considerably between the three collection techniques suggesting that multiple techniques likely provide a more comprehensive sample of biting midge fauna.

This research intends to design, assemble and evaluate the performance of an eco-friendly solar light trap to reduce the insect population in rice fields as well as to minimize the use of harmful chemical pesticides. An AutoCAD drawing tool 2016 was used to sketch the design of solar light trap. The main component of this light trap was bulb, solar panel and battery. Design of solar panel and battery was done considering by 5W LED bulb. A total of five bulbs with different colors were selected to test the insect’s reaction by visible light. Study indicated that ultra violet-blue bulb showed the best performance compare to others based on the high percentage of insect trap (31.22%). A 20-watt solar panel and two 4.5 ah batteries of 6 volts were used to operate the solar light trap. The current, voltage, solar intensity was recorded to check overall performance of solar panel. The solar panel generated more power in April than May due to higher solar radiation in the study area. Study suggested that only 4.26 sunshine hours were required to full charge the battery. The solar light trap was operated 5.5 hour in night which was sufficient to reduce the insects in rice field. Moreover, the light sensor was showed 100% functional for ON/OFF purposes. The dominant insects like yellow stem borer (YSB), green leafhopper (GLH) were mostly observed. The average largest numbers of YSB and GLH were 900 and 600 respectively. In conclusion, the solar light trap is eco-friendly, low cost, easy and self-sufficient in term of solar energy. Finally, the newly developed light trap could be helpful for manufactures, decision makers, and engineering community as well as farmers as a best tool to protect nature in comparison to other pesticide using practices.

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.

ABSTRACTRecolonization of Natural Enemies after Insecticide Application in Rice Planting AreaThe study to assess recolonization of natural enemies after insecticide application in rice planting area was carried out in the wet season of 2013 at Karawang Regency. The application of several insecticides of rynaxypyr, fipronil, dinotefuran, pymetrozine, imidacloprid, and BPMC was conducted when brown plant hopper population was rising and yellow stem borer flight was occurring. Observation of natural enemies was carried out on 1, 3, 5, 7, 10, 15, and 21 days after application (DAA) using sweep net for 4 swings per plot. The results showed that spiders were relatively safe to the rynaxypyr and fipronil insecticides with hampered recolonization index (HRI) of very light and light where recolonization occurred on 1 DAA. All tested insecticides highly affected Telenomus rowani with HRI of heavy to very heavy that this parasitoid recolonized at 7 DAA. On the other hand, all insecticides showed low influence on the recolonization of Tetrastichus schoenobii with HRI from unhampered to light hamper and the recolonization occurred on 1 DAA. The effect of rynaxypyr, fipronil, imidacloprid and BPMC application on Oligosita sp. and Anagus sp. recolonization was categorized to be low with HRI of light hamper that the recolonization happened at 1 DAA and 5 DAA, respectively. The insecticides of fipronil and BPMC were considered to slightly hamper the chironomid with the light value of the HRI and the chironomid recolonized at 1 DAA on fipronil and 3 DAA on BPMC.Keywords: Effect of insecticides, Recolonization of natural enemy, RiceABSTRAKPenelitian rekolonisasi musuh alami setelah aplikasi insektisida di pertanaman padi dilakukan pada musim hujan 2013 di Kabupaten Karawang.

Studies were carried out at Agricultural Research Station, Seethampeta in Andhra Pradesh during the kharif season for three consecutive years starting from 2017 to 2019 on the population dynamics of insect pests occurring in paddy and also to assess the influence of weather parameters on insect pests. The insect pests observed in the light trap catches were, Yellow stem borer, Gall midge, Leaf folder, Green leafhopper, Plant hopper (BPH/WBPH) and Grasshoppers. The light trap catches of rice insect pests were recorded at weekly interval during 32nd Standard Meteorological Week (SMW) to 52nd Standard Meteorological Week (SMW) and the data were correlated with the weather parameters. The results revealed that more number of adults of Yellow stem borer were noticed during the year 2019 from 45th to 48th SMW and the correlation studies revealed that that maximum temperature, minimum and maximum relative humidities had significant positive influence and regression value of R2 (743, 638 and 726 during 2017, 2018 & 2019). The population of gall midge was negligible during the year 2017 and 2018. Whereas, in 2019 peak was notice during 38th SMW (15 No’s) maximum relative humidity has positive relation with increase in the gall midge population. Leaf folder adults were trapped more in the light traps during the year 2019 with peak catches of 11.00 No’s on 42nd SMW and were positively correlated with maximum temperature, minimum and maximum relative humidities. Similarly, leafhopper, brown leaf hopper, grass hoppers were positively correlated with the relative humidity.

Rice crop is affected by many insect pests like White Stem Borer, Yellow Stem Borer and Pink Stem Borer. Rice stem borers are main pests affecting rice crop from nursery to physiological maturity including them in key pests. These studies had been carried out to discover the encouraging and antagonistic boundaries of weather parameters for the rice stem borers. As per result of studies, the population was recorded higher from mid-March to 1st week of May and then it escalated again from 2nd week of August to a maximum in September in case of Yellow Stem Borer (Scirpophaga incertulus) and White Stem Borer (Scirpophaga innotata) of rice during the both years 2017-2018; while in case of Pink Stem Borer population recorded from mid-September to the last week of April in 2017 and lasted till 4th week of May 2018. On evaluating the weather conditions specially temperature and relative humidity, it was detected that insect trap catches noted inside a certain range of temperature that varies from 18-35°C in case of White Stem Borer and 17-34°C for Yellow stem borer of rice. Extreme catches were documented in April and September inside a temperature range of 26-32°C considering it ideal series of temperature for insect light trap catches and activity of yellow and white stem borer. However, in case of pink stem borer above 32°C no catch was observed.
