An integrated pest control on vegetables crops in the fields,  is one of the control method to suppress the insect pest population , therefore farmer do not depend on the chemical controls that have negative effect both on the environment and human as well as animal.  The science and technology program for communities [IbM] aim to get a package of integrated pest control technology that is enviromentally friendly and it is derived from Indonesian microbial resources to support sustainable agriculture system .  To achieve  the goal, the program  implemented  through counseling, plot demonstration and field work.  These activities provided motivation  to farmers to be able to use biological agents combined with culture control to suppress population of insect pest and vegetables through the extension activities and the plot  demonstrations.  The IbM activity gave benefit to farmers by transfer knowledge through extension methods on how to get and use biopesticides with its theory and it can be directly practiced by farmers in the form of a plot demonstrations.

Entomopathogenic fungi are very heterogeneous group used for management of insect pest. From last 2 decade in the search for new avenues in biological control, the importance of entomopathogens has been highlighted as an environmental friendly pest control method came in existence which is sustainable solution towards integrated pest control program. Fungi, which induce disease symptoms in insects, include fungi from quick killers to absolute parasites that provide disease symptoms in the host. Insect order and families are reviewed which were affected severely by entomopathogenic fungi.

The international importance of the potato crop needs no stressing and its protection from insect pests is correspondingly important. This article reviews the wide variety of control methods currently in use. In present circumstances integrated pest control methods are desirable on environmental grounds, but in practice the careful monitoring required makes this difficult for the individual grower.

<p>Penerapan komponen teknologi pengendalian hama ramah lingkungan dilaksanakan di daerah pengembang-an 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 ra-mah lingkungan diharapkan menjadi solusi yang tepat untuk mengatasi masalah serangga hama pada tanam-an kapas dan dapat diterima oleh petani. Pengendalian serangga hama kapas yang diterapkan adalah pengen-dalian 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 ha-ma konvensional (pengendalian hama menggunakan insektisida kimiawi sintetis seperti yang biasa diterap-kan oleh petani). Hasil penelitian menunjukkan bahwa penerapan komponen teknologi pengendalian hama ra-mah 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 ka-pas selalu di bawah batas ambang kendali dan tidak berbeda dengan pengendalian hama secara konvensio-nal. 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 da-pat diterima, tetapi petani masih enggan untuk melaksanakannya.</p><p> </p><p>Application of environmentally friendly pest control technology is expected to be the best solution to over-come 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 environmen-tally 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 tech-nology 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 en-vironmentally friendly pest control technology can be accepted by cotton farmers, including the action thres-hold concept. However, the farmers were mind to implement the action threshold as it is too complicated for them.</p>

Context: Entomopathogenic fungi have been recognized as viable alternate options to chemicals in insect pest control. Unlike other potential biocontrol agents, fungi do not have to be ingested to infect their hosts but invade directly through the cuticle. Entry into the host involves both enzymic degradation of the cuticle barrier and mechanical pressure. Production of a range of cuticle degrading enzymes is an important event in the interaction of entomopathogenic fungi and host. Enzyme secretion is believed to be a key contributor for the virulence of a fungal isolate. Objectives: The potentiality of nine isolates of M. anisopliae were tested to produce to produce three important cuticle degrading enzymes, viz., chitinase, protease and lipase. Materials and Methods: Nine isolates of M. anisopliae were evaluated for chitinase, protease and lipase enzyme production by determining the enzyme index and activities. Results: Chitinase index of these isolates were ranged from 1.5 to 2.2 and chitinolytic activity from 0.525 to 1.560 U/ml. The isolates showed protease index in the range of 1.2 to 3.3 and the activity ranged from 0.020 to 0.114 U/ml. Lipase index ranged from 1.15 to 7.0 and the enzyme activity ranged from 0.153 to 0.500 U/ml. A strong relationship was observed between virulence of the isolates and cuticle degrading enzyme production as increased enzyme production was observed for virulent isolates. Conclusion: In the present study three isolates as (MIS2, MIS7 and MIS13) demonstrated cuticle degrading enzyme (CDE) that indicate higher virulence based on the bioassay conducted earlier by the authors as strongly substantiating the role of CDEs is considered the virulence of Metarhizium isolates. So, these isolates may be as ecofriendly insect-pest control agent in future. DOI: http://dx.doi.org/10.3329/jbs.v20i0.17648 J. bio-sci. 20: 25-32, 2012

Intercropping of aromatic plants provides an environmentally benign route to reducing pest damage in agroecosystems. However, the effect of intercropping on natural enemies, another element which may be vital to the success of an integrated pest management approach, varies in different intercropping systems. Rosemary, Rosmarinus officinalis L. (Lamiaceae), has been reported to be repellent to many insect species. In this study, the impact of sweet pepper/rosemary intercropping on pest population suppression was evaluated under greenhouse conditions and the effect of rosemary intercropping on natural enemy population dynamics was investigated. The results showed that intercropping rosemary with sweet pepper significantly reduced the population densities of three major pest species on sweet pepper, Frankliniella intonsa, Myzus persicae, and Bemisia tabaci, but did not affect the population densities of their natural enemies, the predatory bug, Orius sauteri, or parasitoid, Encarsia formosa. Significant pest population suppression with no adverse effect on released natural enemy populations in the sweet pepper/rosemary intercropping system suggests this could be an approach for integrated pest management of greenhouse-cultivated sweet pepper. Our results highlight the potential of the integration of alternative pest control strategies to optimize sustainable pest control.
