“…Syrphid larvae were observed to be vastly outnumbered by aphids. Laboratory feeding studies show that one syrphid can kill 132-507 aphids during larval development depending on the syrphid species, environmental conditions, and aphid species (Soleyman-Nezhadiyan and Laughlin 1998, Hopper et al 2011). Hopper et al (2011 reported that individual T. marginatus killed 132 lettuce aphids (Nasonovia ribisnigri Mosley) over the larval stage.…”

“…A. obliqua is also a well-known aphidophagous flower fly with potential as BCA (Smith and Chaney, 2007;Noma and Brewer, 2008;Hopper et al, 2011) but immature stages of both Allograpta species are not yet distinguishable using morphology (Arcaya, 2012).…”

The average recorded duration of A. exotica development was 2.0, 7.4 and 5.7 days for eggs, larvae and pupae respectively, and 15.04 days from egg to adult emergence. The adult longevity was not significantly sex dependent, but imagoes lived longer than in previous studies. The offspring sex ratio was favorable to males. The mortality and survival rate were recorded on a daily basis for all immature stages and adults. The age specific survival rate was determined and the highest mortality occurred in eggs followed by mortality in 1st and 2nd instar larva.Moreover, in the present study different levels of aphid densities 10, 30, 40, 50, 60, 70, 80 and 100 were used to calculate the functional response. Based on logistic regression analyses the three instar larvae and the whole larval stage (first to third instar) exhibited a type II functional response. Handling time was shortest for the third larval instar followed by second and first instars. Potential use of A. exotica in augmentative biological control is discussed.

“…Farmer was suggested for better and safe utilization of insecticides against predatory syrphids in sustainable manner in horticulture of Kashmir (Abrol, 1993). There was need in today's context to reduce pesticide usage on the world's crop and optimize natural bio-control (Hopper et al, 2011). Hence, the question of information pertaining to biodiversity and successful utilization of syrphid flies in today's context of pest management is not yet explored due to sole reliance on chemical control.…”

“…Among the important predators of aphid, syrphids play a dominant role next to coccinellids (Khan et al, 2016). However, not much attention has been paid to make studies on syrphids in agro ecosystem (Hopper et al, 2011).…”
