“…(Neuroptera: Chrysopidae), have been shown to increase in cotton stripcropped with sorghum, corn or alfalfa (Smith and Reynolds, 1972;Massey and Young, 1975). It has also been reported that strip-cropping has a potential role in increasing predator numbers and reducing the abundance of cotton aphids in Texas cotton (Parajulee et al, 1997;Parajulee and Slosser, 1999;Slosser et al, 2000).…”

“…Most of these arthropod predators in wheat are also natural enemies of cotton aphids (Zhao, 1995). Compared with monoculture cotton, populations of natural enemies can be increased significantly and cotton aphid populations can be significantly reduced in cotton inter-cropped (Wang, 1993;Xia, 1997) or strip-cropped with wheat (Parajulee and Slosser, 1999). …”

A 2-year study was conducted to evaluate the role of winter wheat, Triticum aestivum L., as a potential relay crop to conserve arthropod natural enemies and suppress cotton aphids, Aphis gossypii Glover, in seedling cotton. The results suggested that the natural enemies that moved from the adjacent wheat fields to cotton fields with the maturity and harvest of wheat could keep the cotton aphid population at the edges (0-4 m) of cotton fields under the action threshold of 100 aphids/m 2 . Data also suggested that the wheat strip served as a reservoir to conserve arthropod predators and ''relayed'' its predators to cotton when wheat matured and senesced.

“…Perlakuan benih dengan insektisida berbahan aktif imidakloprit dapat memberikan nilai tambah pada varietas kapas seri Kanesia (Sunarto dan Nurindah, 2007). Selain itu, dengan menambah keanekaragaman vegetasi melalui sistem tanam tumpang sari atau polikultur pada suatu ekosistem dapat meningkatkan populasi predator yang berfungsi sebagai musuh alami yang dapat mengendalikan serangga hama (Parajulee dan Slosser, 1998;Tillman et al, 2002;Anand et al, 2001). …”

ABSTRAKPenerapan komponen teknologi pengendalian hama ramah lingkungan dilaksanakan di daerah pengembangan kapas di Kecamatan Jati, Kabupaten Blora, Jawa Tengah di lahan petani seluas ± 5 hektar yang dimiliki oleh 20 petani pada bulan Maret sampai dengan Oktober 2009. Komponen teknologi pengendalian hama ramah lingkungan diharapkan menjadi solusi yang tepat untuk mengatasi masalah serangga hama pada tanaman kapas dan dapat diterima oleh petani. Pengendalian serangga hama kapas yang diterapkan adalah pengendalian serangga hama ramah lingkungan dengan komponen pengendalian yang terdiri atas seed treatment dengan insektisida imidakloprit dan penyemprotan insektisida botani ekstrak biji mimba berdasarkan ambang kendali yang mempertimbangkan keberadaan musuh alami dibandingkan dengan pengendalian serangga hama konvensional (pengendalian hama menggunakan insektisida kimiawi sintetis seperti yang biasa diterapkan oleh petani). Hasil penelitian menunjukkan bahwa penerapan komponen teknologi pengendalian hama ramah lingkungan yang terdiri atas seed treatment, insektisida botani ekstrak biji mimba, dan ambang kendali dengan mempertimbangkan keberadaan musuh alami, terbukti dapat menekan populasi serangga hama kapas selalu di bawah batas ambang kendali dan tidak berbeda dengan pengendalian hama secara konvensional. Pengendalian hama ramah lingkungan lebih aman terhadap musuh alami dengan pendapatan usaha tani kapas Rp621.250,00 lebih tinggi dibanding pengendalian hama secara konvensional. Teknologi pengendalian hama ramah lingkungan dapat diterima oleh petani, kecuali teknologi ambang kendali yang secara konsep dapat diterima, tetapi petani masih enggan untuk melaksanakannya.Kata kunci: Gossypium hirsutum, kapas, seed treatment, pestisida nabati, ambang kendali Environmentally Friendly Cotton Pest Control Technology ABSTRACTApplication of environmentally friendly pest control technology is expected to be the best solution to overcome insect pest problem on cotton crops and can be accepted by farmers. The research was conducted in the area of cotton development in Jati District, Blora Regency, Central Java on farmers' land area of 5 hectares owned by 20 farmers from March to October 2009. The applied treatments were: application of environmentally friendly pest insect control components, ie: seed treatment and botanical neem seed extracts insecticide sprayed based on an action threshold that considers the presence of natural enemies took in to account, compared with conventional pest control (pest control using synthetic chemical insecticides commonly used by the cotton farmers). The results showed that the application of environmentally friendly pest control technology suppressed cotton insect pest population with no negative effect on natural enemies, and retained seed cotton production, increased the income of cotton farming as much as Rp621.250,00. Components of environmentally friendly pest control technology can be accepted by cotton farmers, including the action threshold concept. However, the farmers were mind to im...

“…Diversification of crops within a production system can have several desirable consequences for farmers. One of the well-documented benefits of diversification is lower insect pest pressure, and evidence is accumulating that diversifying cropping systems increase and support natural enemy populations, and consequently increase the effectiveness of biological control (Parajulee and Slosser, 1999;Guerena and Sullivan, 2003;Brewer and Elliott, 2004). Furthermore, when aphid-resistant wheat cultivars are incorporated into a diversified system, the combined effect of natural enemies and host plant resistance can be interactive, resulting in a reduced probability of aphids reaching ElLs (Brewer and Elliott, 2004).…”

Areawide Pest Management: Theory and Implementation

View full text Add to dashboard Cite

The cereal aphid areawide pest management (AWPM) programme in wheat was a multifaceted approach that included detailed sociological and economic evaluations, experimental and demonstration pest studies and a comprehensive education/outreach programme that is still ongoing. In this chapter, much of the discussion focuses on the methodology and findings from the regionwide demonstration sites, which included monoculture (continuous wheat or wheat-fallow) systems and diversified wheat production systems, set up at the farm landscape scale and paired throughout the Great Plains region (USA). Ultimately, economic findings from these demonstration farms will support the justification for increasing adoption of diversified farming systems. However, data on aphid, natural enemy (parasitoids and predators) and weed densities at paired demonstration sites provide evidence as to the mechanisms involved for AWPM of cereal aphids in wheat.
