زیست شناسی مگس شکارگر [Leucopis glyphinivora Tanas. (Dip.: Chamaemyiidae)] و کارایی آن در مبارزه بیولوژیک با شته سیاه باقلا ( Aphis fabae Scop. )
The biology of predatory fly, Leucopis glyphinivora Tanas. was studied under greenhouse conditions. Adult longevity was 8 days and the average fecundity was 35.7 eggs. Incubation period, the 1st, 2nd, 3rd larval instars and puparium duration averaged 2.7, 2.16, 3.48, 5.7 and 8.45 days, respectively. Each generation lasted about one month. The predator efficiency was studied by applying the egg ...

متن کاملImpact of plant nutrients on the relationship between a herbivorous insect and its symbiotic bacteria.
The interactions between herbivorous insects and their symbiotic micro-organisms can be influenced by the plant species on which the insects are reared, but the underlying mechanisms are not understood. Here, we identify plant nutrients, specifically amino acids, as a candidate factor affecting the impact of symbiotic bacteria on the performance of the phloem-feeding aphid Aphis fabae. Aphis fa...
متن کاملLarval Performance and Kill Rate of Convergent Ladybird Beetles, Hippodamia convergens, on Black Bean Aphids, Aphis fabae, and Pea Aphids, Acyrthosiphon pisum
Generalist predator guilds play a prominent role in structuring insect communities and can contribute to limiting population sizes of insect pest species. A consequence of dietary breadth, particularly in predatory insects, is the inclusion of low-quality, or even toxic, prey items in the predator's diet. Consumption of low-quality prey items reduces growth, development, and survival of predato...
متن کاملEffect of petroleum-derived substances on life history traits of black bean aphid (Aphis fabae Scop.) and on the growth and chemical composition of broad bean
The aim of the study was to determine the effects of various petroleum-derived substances, namely petrol, diesel fuel and spent engine oil, on life history traits and population dynamics of the black bean aphid Aphis fabae Scop. and on growth and chemical composition of its host plant Vicia faba L. Each substance was tested separately, using two concentrations (9 g kg-1 and 18 g kg-1). The expe...
