“…This will help in reducing the expenses and increase their cane yield. The present findings are also in agreement with earlier studies by Thirumurugan et al (2006), Geetha et al (2009), and Sattar et al (2016) who have reported successful management of sugarcane borers through augmentative releases of trichogrammatids.…”

Background Biological alternatives to pesticides in agriculture do not harm non-targets organisms including natural enemies of insect pests. Experiments were conducted at sugarcane fields during 2015 to 2019 to assess large scale biocontrol practices, involving inundative releases of trichogrammatids against lepidopteran borers in comparison to conventional chemical-based farmers’ practice. Main body Eight releases each of Trichogramma chilonis Ishii and Trichogramma japonicum Ashmead were made at 50,000 ha−1 at 10 days interval for the management of sugarcane stem borer, Chilo infuscatellus Snellen and the sugarcane top borer, Scirpophaga excerptalis (Fabricius) (Lepidoptera: Crambidae), respectively. Likewise, 10–12 releases of T. chilonis were made at 50,000 ha−1 at 10 days interval for the management of sugarcane stalk borer, Chilo auricilius Dudgeon (Lepidoptera: Crambidae). The biocontrol intervention was compared with farmer’s practice (chemical control) in managing these borers. The results showed that farmers’ practices and biocontrol treated fields resulted in a lower incidence of C. infuscatellus (1.1, 2.9%) and S excerptalis (1.7, 3.9%) than the untreated control fields, wherein the mean per cent incidence of these borers (6.8, 8.5%) was significantly higher. The incidence of C. auricilius was also lower in augmented fields (2.8%) than untreated fields (7.3%). The yield data indicated that farmers adopting biocontrol practices were able to get comparable yield and benefit: cost ratio than farmers’ practice, both being better than untreated control. Moreover, in biocontrol fields, parasitism rate on the factitious host, Corcyra cephalonica Stainton cards was estimated. Conclusion Thus, the study highlights the significance of adoption of biocontrol-based technology over a long run to provide sustainable system of sugarcane insect pest management and economic benefits to the stakeholders.

“…The interaction of habitat modifi cation and wasp release signifi cantly reduced pepper damage as a result of synergy between the tactics. Thirumurugan et al ( 2006 ) conducted fi eld experiments on improving Trichogramma effi cacy using intercropping of soybean for the control of sugarcane shoot borer Chilo infuscatellus (Snellen) in tropical India and found that plots intercropped with soybean showed maximum parasitization.…”

Biological Control of Insect Pests Using Egg Parasitoids

View full text Add to dashboard Cite

Mass production and inundative release of Trichogramma , especially T. chilonis , has emerged as a promising component of IPM program on several crops in India. Selective (safer) synthetic pesticides have been identifi ed and alternatives like biocontrol agents and biopesticides have become easily available. Chemical ecology research has opened up means of improving kairomonal utilization for enhancing the impact of mass released egg parasitoids. The concurrent use of predators (e.g., Chrysoperla ), microbials (e.g., Bt ., N.P.V.), and botanicals (e.g., neem) has been shown to be benefi cial against several caterpillar pests. The scope for enhancing the availability of refugia and fl owering plants for pollen/nectar source are reckoned as useful means of in situ conservation of native egg parasitoids. Biorationals (e.g., spinosad) also offer an eco-friendly component for integration.

“…Doubts were expressed on the efficacy of T. chilonis in the control of internode borer, based on analysis of empirical data of host and parasitoid biology [277], even as combined use of T. chilonis with 5% tomato extracts or soybean intercrop was found to be superior to the parasitoid release alone [278]. The impact of release frequency of T. chilonis against internode borer was examined in field trials [279].…”

Insect pests constitute a major biotic stress in sugarcane in India as they attack the crop from the time of planting until almost harvest, inflicting yield and sugar losses. Biological control has always received a prominent position among the pest management tools, facilitated by the unique semi-perennial crop habitat and low pesticide usage. Biocontrol research of the early 1930s and 40s was characterized by surveys focusing on identification and studies on the basic biology of natural enemies. Conservation and redistribution , and introduction and colonization of predominant parasitoids was practiced very early, and even in the recent past, with remarkable success. Mass multiplication and field evaluation that began in the early decades continue today, as is demonstrated by the use of the most exploited parasitoid Trichogramma chilonis. Several parasitoids and predators of borers and sucking pests were investigated systematically when the need arose. Among entomopathogens, granulosis viruses and fungi received considerable attention; a simple formulation of Beauveria brongniartii reached commercial production for the control of the white grub Holotrichia serrata. In recent years, isolates of Bacillus thuringiensis from sugarcane soil have been examined and a scarabaeid-specific cry gene has been identified. Preliminary studies of kairomonal principles from borers as attractants to the larval parasitoid Cotesia flavipes have been carried out. Organizational support to the cause of biological control includes coordinated research efforts from government agencies, production of biocontrol agents by commercial insectaries and promotion of technologies by the sugar industry. In this review, we chronicle the major research findings over the past eight decades, portray an overview of their significance and project the prospects and priorities for biological control research and promotion in the country.
