The susceptibility of six milled rice varieties (IR-64, Ciherang, Membramo, Cibogo, Sembada, and Intani-2) to the Lesser Grain Borer (Rhyzopertha dominica, F) was studied by No Choice Test Method under laboratory condition (27 ± 2°C 65 5% RH). Susceptibility assessed on basis eggs number laid female insects, F1 progeny emerged, weight loss infested samples also Dobie's Index susceptibility. results revealed that emerged were significantly low in Membramo variety followed IR-64, Sembada...

Biodiversitas 23: 4510-4516. White stem borer, innotata, is an important plants that needs attention because the quite large Luwu Raya. This attacks at all growth stages can result yield losses production. Synthetic insecticides are a common control technique used by farmers to these pests....

As an important pest, Helopeltis Antonii reduces cocoa yields ca. 32-44 %. Related to H. antonii, this research aimed identify the arthropods diversity, population and attack intensity of antonii in three different managements plantations i.e. Kedaton, Banjarsari Nogosari, Jember district, East Java, Indonesia from February 2014 2015. The arthropod collection was done by visually, sweep net, yellow pan, malaise pitfall traps. Arthropods diversity similarity were analyzed Margalef species...

This research aims to assess the environmental factors that affect abundance of scales populations on apple crop. The study was conducted in July 2012 January 2013. at two sites with different altitude. Bumiaji village's altitude is ±900 m and Tulungrejo ±1,515 asl. Multiple linear regression analysis determine Based results analysis, air temperature humidity Binangun while rainfall long solar radiation have no effect. Scales population crop influenced by one week before. temperature, abun...

The Research was aimed to identifythe diversity of arthropods in Cocoa plantation inthree strataof shade tree. conducted Rahmat village, the sub-district Palolo, District Sigi, Province Central Sulawesi, Indonesia from December 2012 June 2013.Berlese funnel, Pitfall, Malaise and Light trap were used collect arthropod samples. There five indices such as species richness (R), evenness (E), (H`and D), similarity (Iss) analyze cocoa plantations. result showed that (R) under two strata tree, (E)...

In order overcome loss yields from presence pests, alternative new approaches are sought by solving problem can have a sustainable impact applying manipulation. Habitat...

Abstract. Thei RSP, Abadi AL, Mudjiono G, Suprayogo D. 2020. The dynamics of Arthropod diversity and abundance in rice field ecosystem Central Lombok, Indonesia. Biodiversitas 21: 5850-5857. Arthropods have roles as pests, decomposers, pollinators, natural enemies pests. Natural play a vital role pest population control by predation or parasitism. A study the arthropod community was conducted Indonesia from December 2009 to March 2010 order elucidate composition, structure, dynamic...

Madura is enriched by great diversity despite of its infertile natural condition. This condition influences fruit flies existence and diversity. Purpose this study was to investigate the distribution with their host in region. Sampling methods were collection (rearing) trapping using Steiner-type trap that set 48 locations several villages Bangkalan, Sampang, Pamekasan, Sumenep regencies. Steiner traps combined 2 different attractants, such as methyl eugenol (ME) Cue Lure (CL). There 5...

Rhyzopertha dominica reduces the weight of rice production at approximately 40 %. This study aimed to investigate physical and biochemical characteristics resistance in different varieties initial moisture content their susceptibility against R. dominica. The consisted 2 experiments: (i) free-choice, (ii) no-choice tests. These experiments were conducted by combining 6 (Vi): IR-64, Ciherang, Membramo, Cibogo, Sembada, and, Intani-2, 4 levels (Ki): 10, 12, 14, 16 observed variables for...

Climate change is closely related to changes in abiotic conditions. These could have an impact on agricultural cultivation and affect the existence of arthropods. Different environmental conditions will influence distribution patterns, richness diversity arthropods living cultivated land. The research was conducted at 8 rice locations Greater Malang. Observation using pitfall yellow pan traps, with a diagonal pattern. total obtained were 3,937 individuals, 39 families, 46 genera 48 species....

The cultivation of tobacco is one users agro-chemical substances such as insecticides, herbi-cides, defoliants, and fertilizers among other food crops plants with high economical value. use these chemicals may bring negative effects regarding the richness abundance arthropods. study arthropod community in Virginia ecosystem was carried out Central Lombok, West Nusa Tenggara Province, during 2010 plantation year. It aimed at finding composition, structure, dynamic diversity around field....
