“…Agrobiont species must have good powers of dispersal (Luczak, 1979;Riecken, 1998) and be better equipped (e.g. through special life history strategies) than other species to survive under agricultural conditions (Toft, 1989;Young & Edwards, 1990;Wissinger, 1997). Agricultural habitats and structurally similar natural habitats can both harbour agrobiont species.…”

A review of the literature showed that spider abundance was increased by diversification in 63% of studies. A comparison of diversification modes showed that spider abundance in the crop was increased in 33% of studies by 'aggregated diversification' (e.g. intercropping and non-crop strips) and in 80% of studies by 'interspersed diversification' (e.g., undersowing, partial weediness, mulching and reduced tillage). It is suggested that spiders tend to remain in diversified patches and that extending the diversification throughout the whole crop (as in interspersed diversification) offers the best prospects for improving pest control. There is little evidence that spiders walk in significant numbers into fields from uncultivated field edges, but diversification at the landscape level serves to foster large multi-species regional populations of spiders which are valuable as a source of aerial immigrants into newly planted crops. There are very few manipulative field studies where the impact of spiders on pests has been measured in diversified crops compared with undiversified controls. It is encouraging, however, that in those few studies an increased spider density resulted in improved pest control. Future work needs are identified.

“…The immigration of natural enemies into arable fields is key for the effective control of pest populations in crops (Wissinger 1997;Schellhorn et al 2014). Our data show that spider immigration into crops is a continuous process, occurring in all six discrete periods.…”

Landscape-scale mass-action of spiders explains early-season immigration rates in crops

et al. 2017

Context Early-season immigration into arable fields by natural enemies is key for effective biocontrol, but little is known about the mechanisms underlying immigration processes. Objectives Here we test the mass action hypothesis for ballooning spiders, stating that local immigration rates are positively related to the amount of spiders in the surrounding landscape. Methods Immigration rates of spiders were assessed by sticky traps in remnant vegetation, in arable land 25-125 m from remnant vegetation, and in arable land further than 400 m from remnant vegetation. The experiment was conducted at 18 locations across two landscapes and repeated three times in a 2-week period in 2007 and 2008. Spider densities in crop and noncrop habitats were assessed by beat sheet sampling and used to calculate spider loads in landscape sectors around the experimental locations at five spatial scales. Results Regression analysis indicated that immigration rates were influenced by meteorological variables and landscape context at 2 km and possibly beyond. Regression models that included spider load at relevant spatial scales received more statistical support from the data than models with the proportion of remnant vegetation and crops. Regression analysis further indicated that wheat and-to a lesser extentremnant vegetation are important habitats for the recruitment of ballooning spiders. Conclusions Our study provides support for the mass action hypothesis by showing that a combination of land-use variables with habitat specific spider densities allows the generation of functional cover types with greatly improved explanatory power.Electronic supplementary material The online version of this article

“…Menurut Wiedenmann & Smith (1997), Wissinger (1997), Herlinda & Effendy (2003), artropoda predator mempunyai kemampuan untuk menyesuaikan diri di ekosistem efemeral. Lahan pinggir di sekitar pertanaman padi dapat berfungsi sebagai tempat berlindung dan sumber musuh alami pertanaman padi pada musim berikutnya.Dengan demikian, musuh alami pada ekosistem tersebut tetap eksis dan berperan dalam menekan populasi hama padi.…”

Analisis kemiripan komunitas artropoda predator hama padi penghuni permukaan tanah sawah rawa lebak dengan lahan pinggir di sekitarnyaSimilarity analysis of predatory arthropods inhabiting the surface area of swampy rice field and its surrounding ABSTRAKDi Sumatera Selatan luas lahan rawa lebak 1,4 juta ha, 12% dimanfaatkan sebagai sawah dan perkebunan, sisanya belum dikelola. Penelitian ini bertujuan mengetahui kemiripan komunitas artropoda predator penghuni permukaan tanah sawah rawa lebak dengan lahan pinggir yang berada di sekitarnya. Penelitian dilakukan di Kabupaten Ogan Ilir, Kabupaten Musi Banyuasin, dan Kota Palembang, Sumatera Selatan. Di setiap lokasi dipilih empat tipe habitat rawa lebak, berupa pertanaman padi, semak-semak, padang ilalang, dan hamparan gulma berdaun lebar. Pengambilan sampel artropoda predator penghuni tanah menggunakan perangkap sumuran. Pemasangan perangkap dilakukan sebanyak lima kali, yaitu 15 hari sebelum padi ditanam, saat tanaman padi berumur 1, 2, dan 3 bulan, serta 15 hari setelah panen. Hasil penelitian menunjukkan kelimpahan relatif artropoda predator di permukaan tanah di pertanaman padi adalah 95,03% dan di habitat lahan pinggir disekitar pertanaman padi adalah 95,12-97,21%. Keanekaragaman spesies artropoda predator di permukaan tanah pada habitat padi dengan habitat lahan pingir menunjukkan tingkat kemiripan 0,73-0,84. Habitat lahan pinggir di sekitar pertanaman padi dapat menjadi penampung artropoda predator dan sumber musuh alami hama tanaman padi pada musim tanam padi berikutnya. Kata kunci: padi, lahan persawahan, pengendalian hayati ABSTRACTThere are approximately 1.4 million hectares of swampy area in South Sumatera, but only 12% of those are being used as farm and plantation. The purpose of this research was to investigate the similarity of arthropod community inhabiting swampy rice field and its surrounding area. This research was conducted in South Sumatera Province covering regency of Musi Banyuasin and Palembang. Four types of swampy area were selected from each location, i.e. rice field, thicket, bush, and swampy land inhabited by broad-leaf weeds. Pitfall trap used to collect arthropod and it installed at five different times. i.e. 15 days before rice planting, one month, two months, and three months after planting, and 15 days after harvest time. The result showed that relative abundance of predatory arthropod dwelling soil in rice field was 95.03%, and habitat surrounding rice field was 95.12-97.21%. The level of similarity of arthropod species between rice field ecosystem and PENDAHULUANLuas lahan rawa lebak di Sumatera Selatan ada sekitar 1,4 juta ha, 12% dimanfaatkan sebagai lahan pertanian, berupa sawah, lahan perkebunan, dan sisanya masih belum dikelola (BPS 2007). Di ekosistem sawah rawa lebak Sumatera Selatan belum pernah dilaporkan terjadinya peledakan populasi hama padi. Diduga hal itu ada kaitannya dengan budi daya tanaman padi di sawah rawa lebak Sumatera Selatan yang tidak mengaplikasikan pestisida.Tumbuhan liar berupa tumbuhan semak semusi...
