“…Según Butt y Muhammad (2012) el riego afecta la distribución y la abundancia de las arañas en los cultivos. Srikanth et al (1997) encontraron que el riego resultó negativo para la población de arañas en un cultivo de caña de azúcar (siendo más dañino el riego por gravedad que por goteo superficial). En cambio, Andrey et al (2014) registraron que el riego tuvo un efecto positivo en la riqueza de artrópodos en un pastizal, que al aumentar los herbívoros incrementaron los depredadores.…”

En el presente trabajo, se evaluó la araneofauna durante todo el periodo fenológico del cultivo de algodón, utilizando dos técnicas de muestreo (búsqueda directa y trampas de caída). Se registraron 2304 individuos, agrupados en 50 especies y 18 familias. Las arañas estuvieron presentes durante todo el periodo del cultivo, relacionándose positivamente a su desarrollo fenológico, y donde las prácticas agronómicas, la temperatura y humedad no fueron influyentes en su abundancia, excepto por la cosecha, actividad que sí influenció negativamente sus poblaciones.

“…A technique was developed to evaluate the predatory role of spiders [233]. Cultural practices like manual weeding, earthing-up and detrashing significantly reduced spider abundance, while furrow irrigation was more detrimental than drip irrigation to spiders, and postharvest trashburning drastically reduced spider abundance [234]. Among the coccinellids, Cheilomenes sexmaculata was widely distributed and fed on the nymphs and adults of aphids [235].…”

“…Early and sustained activity of A. barodensis parasitoids in unsprayed plots rather than in aerially sprayed plots, despite lack of difference in pest population status [370], emphasized the role of conservation of natural enemies in a stable crop system. Deleterious effects of earthing-up, detrashing, post-harvest trash-burning and furrow irrigation on scale insect natural enemies [202] and predatory spiders [234] suggested the need to selectively avoid these practices. Although pulse intercrops failed to increase predator numbers [236], higher spider numbers in a weedy crop [234] indicated the possibility of enhancement of natural enemy abundance through habitat manipulation [371].…”

Implementation of such conservation and enhancement practices may, however, be governed more by agronomic and economic than entomological considerations.…”

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.

“…Furthermore, fire and pesticide can eliminate other organisms in the sugarcane plantations, reducing the amount of forage for birds and rodents. For example, studies in other countries have shown the negative impacts of agro-industrial management associated with sugarcane production on microbial communities [50], bacterial communities [51], arthropods [52], and spider populations [53]. M. natalensis and Arvicanthis spp.…”

Despite the intense debates on the land acquisition effects of large-scale Ethiopian sugarcane plantations and the consequences for food security, the impact on biodiversity has received less attention. We compared remnant patches in the sugarcane zone to the adjacent woodlands to determine the impacts of sugarcane on the diversity, composition, and structure of woody species. We recorded individual woody specimens with diameter at breast height (DBH) ≥ 2.5 cm from 56 quadrats of 200 m 2 at each site in a systematic, random, and gradient-oriented transect design. In addition, we employed a trait-based risk assessment framework to examine the threat posed by agro-industrial sugarcane production on mammals, birds, and rodents. A total of 56 woody species, 38 in the woodlands and 30 in the sugarcane zone, were identified. The proportion of non-native woody species was higher (63%) in the sugarcane zone than in the adjacent woodlands (1%). The rodents and mammals were more abundant in the woodlands than in the sugarcane zone. Although we did not investigate all of the bird and mammal species, our results identified six rodent species, five mammal species, and one bird species as susceptible to sugarcane agriculture activities. The results suggest that large-scale agro-industrial sugarcane production impacts species diversity, composition and abundance of species, and species' resource requirements.
