“…The present results were in conformity with Arya et al (2016) who also concluded maximum richness, highest abundance and huge diversity of insects in medicinal plants during rainy season, followed by summer and winter seasons. In contrast, Balakrishnan et al (2014) concluded that diversity index and species richness were higher in pre-monsoon season than in summer season. The inverse Simpson and evenness index was highest for R. serpentina and lowest for V. jatamansii, as reported earlier by Najar and Bashir (2016).…”

Present study was conducted within the herbal garden of International Centre for Integrated Mountain Development (ICIMOD) in Godawari of Kathmandu valley to explore the insect communities in medicinal plants. Five medicinal plants, viz. Rauvolfia serpentina (= Sarpagandha), Urtica dioca (= Sissnu), Zanthoxylum armatum (= Timur), Valeriana jatamansii (= Sungandhawal) and Mentha spicata (= Pudina) were selected for the study. Insects were randomly sampled during four seasons from September 2017 to June 2018 using different collecting techniques, like hand picking, pit-fall traps, net-sweeping and stem beating. A total of 869 insects individuals belonging to 42 different genera were collected and identified. It was found that the abundance of insects was high during spring season (299 insects comprising 35 % of collected species), followed by summer (255 insects comprising 29 % of collected species) and winter (219 insects comprising 25 % of collected species) seasons, and low during autumn season (96 insects comprising 11 % of collected species). It was further found that the abundance of insect species was temperature-dependent, but was independent of relative humidity. The maximum indicator species were present on M. spicata. Taxonomic distinctness (delta+) of insects was high on V. jatamansii, but low on U. dioca.

“…Coleoptera beetles are mostly active at night to get food, while at daytime, they hide under stones, leaves, barks, flowing upper groundwater, that represent mangrove and riparian ecosystems (Resh and Carde 2009). Along with Lepidoptera, Coleoptera is a potential bioindicator of moist ecosystems (Balakrishnan et al 2014).…”

Abstract. Budiadi, Musyafa, Hardiwinoto S, Syahbudin A. 2020. Changes in insect biodiversity on rehabilitation sites in the southern coastal areas of Java Island, Indonesia. Biodiversitas 21: 1-7. Rehabilitation activities on coastal areas such as mangrove wetlands and dry-sandy soils may cause a change in the environmental quality, including insect diversity and their role. The research was conducted to compare the effect of stand structure on the rehabilitation areas of the south coast of Java Island and measure insect biodiversity affected by the changes to land cover. Systematic sampling technique was employed in four different land covers, i.e., dryland site of 10-year old Casuarina equisetifolia, and wetland sites of 12-year old Avicennia sp., mixed mangrove, and open grassland. Experimental plots (100 m x 10 m) were established for day- and night-time insect observation and tree inventory. Results showed that stand structure in the rehabilitation areas was low in tree diversity and lesser occurrence of natural regeneration. The insect taxa were dominated by Coleoptera in the Avicennia and mangrove stands, while different types of grasshopper of Acrididae were found in the grassland and Casuarina stands. Richer and more roles of insect species were found in mixed stands than in monoculture, and more in established stands than open grasslands. The rehabilitation activities change the microenvironment and insect diversity but have yet not been considered as an indicator of the success of rehabilitation.

belongs to a group of coastal ecosystems of great ecological importance in Peru. With the objective of evaluating the diversity of terrestrial insects in four plant communities in this ecosystem: Salicornia grassland, grassland, rushes, and cattail stands, monthly samplings were carried out between December-2010 and April-2011. Five collection methods were used: (1) pitfall traps (simple) (2) pitfall traps (necrotraps), (3) Malaise traps, (4) aerial collection with a hand held net, and (5) manual collection. It Alpha and beta diversity indexes at the level of morphospecies, families and orders for terrestrial insects were quantified, as is the most adequate to evaluate wetlands. We identified 150 morphospecies, 73 families and nine orders of terrestrial insects. The largest number of specimens collected was from the Malaise traps (57%). The vegetal community with the richest species was the Salicornia grassland, rushes, grassland, and cattail stands in that order. The proportion of trophic guilds based on the abundance of terrestrial insects was 39% for phytophagous, 34% for predators, 20% for detritivores, and 7% for parasitoids. Only, the Margalef index at the level of morphospecies and families correlated with the environmental temperature. Alpha diversity indices were not associated with relative humidity. The qualitative and quantitative beta diversity dendrograms indicate that in the community of terrestrial insects in the Salicornia grassland, and the rushes they are quite similar to each other. The greatest abundance of terrestrial insects was observed in Diptera in the months of March-2011 and December-2010. The results show that the family taxonomic resolution is adequate to evaluate the diversity of terrestrial entomofauna in the wetlands of Ventanilla,
