“…R. Soc. B (2008) Interplanting crops with flowering herbaceous plants is promoted as a farmscaping technique, since pollen and nectar are essential to the fecundity and longevity of several natural enemy species (Jervis et al 1993;Idris & Grafius 1995). Chaney (1998) found that sweet alyssum, Lobularia maritima, had consistently higher natural enemy to pest ratios than other plants tested.…”

This paper discusses biotic interactions in agroecosystems and how they may be manipulated to support crop productivity and environmental health by provision of ecosystem services such as weed, pest and disease management, nutrient cycling and biodiversity conservation. Important elements for understanding biotic interactions include consideration of the effects of diversity, species composition and food web structure on ecosystem processes; the impacts of timing, frequency and intensity of disturbance; and the importance of multitrophic interactions. All of these elements need to be considered at multiple scales that depend in part on the range of the movement of the organisms involved. These issues are first discussed in general, followed by an examination of the application of these concepts in agricultural management. The potential for a greater use of ecological management approaches is high; however, owing to the nature of complex interactions in ecosystems, there is some inherent unpredictability about responses to management interventions under different conditions. Such uncertainty needs to be accommodated in the development of recommendations for farm management. This requires an increased emphasis on the effective synthesis of complex and often apparently contradictory information and on field-based adaptive research, monitoring and social learning by farmer/researcher collaborations.

“…Os principais açúcares que compõem o néctar (glicose, frutose e sacarose) parecem ser os carboidratos mais apropriados para a criação de parasitóides, pois não só aumentam a longevidade, como também a capacidade de parasitar mais hospedeiros ao longo da vida (Idris & Grafius 1995;Wäckers 2001;Hogervorst et al 2007;Williams III & Roane 2007). Tais açúcares mostraram-se importantes também para T. remus, pois as fêmeas alimentadas com qualquer uma das soluções e com mel, que em sua composição contém 85,48% de açúcares redutores (glicose + frutose) e 3,57% de sacarose sobreviveram mais e geraram mais descendentes do que as fêmeas não alimentadas (Tabela I).…”

“…However, Idris and Abdullah (1997) reported that longevity of adult female M. scalaris was 24.3 days when fed on diluted honey solution. Longevity of Diadegma insulate (Hymenoptera: ichneum onidae), a parasitoid of P. xylostella, ranged from 1,5 to 2.8 days depending on types of food given (Idris and Grafius, 1995;Idris, 1995). This tends to agree with our result that life span of adult M. scalaris is largely dependent on food intake by the larvae (Table 1).…”

“…It has a potential to become a serious pest of vegetable crops in particular the cabbages (Murali, 1991;Ahmad and Ho, 1980). This is because of the damages it caused to cabbage crops, which in some cases, was more severe than damages inflicted by the diamondback moth, Plutella xylostella L., a major insect pest of cabbage crops worldwide (Ooi, 1992;Idris and Grafius, 1995). In an effort to reduce insect pest infestation and pesticide usage many vegetable crops and flowers are commercially grown under netting structure system.…”

Effects of different diets on the development of scuttle flies larvae, Megaselia scalaris (Loew , pupae and adult emergence and longevity were studied. The diets (treatments) used were nutrient agar (NA, control), casein agar (CA), tissue extracts of the round snail, Bradybaena similaris (Fer.), + NA, tissue extracts of the giant African snails, Achatina fulica (Fer.) + NA, and mixed diets (MD, A. fulica tissue + cabbage leaf powder + NA). A comparison was also made on larval and pupal development when larvae were fed on live snails (A. fulica or B. similaris) versus their tissue extract. The developmental time, mean body weight and body length of M. scalaris larvae were significantly different among treatments (p<0.05). Larvae fed on tissue extract diet of B. similaris + NA developed faster than larvae fed on NA or MD. In contrast, mean weight of larvae was highest when reared on the MD, tissue extract of A. fulica + NA and CA. Larvae fed on CA had significantly longer mean body length than larvae fed on other diets. The mean weight of pupa was significantly different among treatments (p<0.05), but not its developmental time (p>0.05). The mean weight of pupa was significantly lower when larvae were fed on NA or tissue extract of B. similaris + NA than on CA, tissue extract of A. fulica + NA or MD. The percent of adult emergence and longevity was also significantly different among treatments (p<0.05). The percent of emergence and longevity of adults that originated from larvae fed CA or tissue extract of B. similaris + NA were significantly higher than adults originated from larvae fed NA and tissue extract of A. fulica + NA. The developmental time of larvae fed live host B. similaris were significantly longer than those fed its tissue extracts + NA (p<0.05), indicating that the larvae had possibly encountered defensive systems of the hosts. In contrast, pupal development took significantly shorter time when larvae were fed live B. similaris + NA than fed it tissue extract (p<0.05). There was no significant difference in the developmental time of both larvae and pupae of M. scalaris when fed either live or tissue extract of A. fulica + NA (p>0.05). The possible use of CA and natural diets for laboratory rearing of M. scalaris as the potential biological control agent of snails is discussed.
