Parental crowding influences life-history traits in Locusta migratoria females.
Parental environments could play an important role in controlling insect outbreaks, provided they influence changes in physiological, developmental or behavioural life-history traits related to fluctuations in population density. However, the potential implication of parental influence in density-related changes in life-history traits remains unclear in many insects that exhibit fluctuating pop...
متن کاملEvidence for the hormonal function of a CRF-related diuretic peptide (Locusta-DP) in Locusta migratoria
Locusta-DP is a corticotropin-releasing factor (CRF)-related diuretic peptide isolated from the migratory locust Locusta migratoria. At nanomolar concentrations, synthetic Locusta-DP stimulated fluid secretion and cyclic AMP production by Malpighian tubules isolated in vitro and increased the rate of amaranth clearance in starved locusts to levels comparable with those observed during post-feed...
متن کاملthe effects of changing roughness on the flow structure in the bends
flow in natural river bends is a complex and turbulent phenomenon which affects the scour and sedimentations and causes an irregular bed topography on the bed. for the reason, the flow hydralics and the parameters which affect the flow to be studied and understand. in this study the effect of bed and wall roughness using the software fluent discussed in a sharp 90-degree flume bend with 40.3cm ...
Effect of Ecdysterone on Food Intake of Locusta migratoria Hoppers
Insect growth and developm ent are controlled by hormones [1, 2], The horm ones were also shown to control food intake and utilization in som e insects [3-8]. Ecdysone is associated not only w ith m oult ing and m etam orphosis but also with processes preparatory to a moult, such as cessation o f feeding and the onset o f the w andering stage [9]. Recently evidence for a relationship between f...
متن کاملEffects of barley chromosome addition to wheat on behavior and development of Locusta migratoria nymphs
Locusta migratoria feeds on various Poaceae plants but barley. Barley genes related to feeding deterrence may be useful for developing novel resistant crops. We investigated the effects of barley cultivar Betzes, wheat cultivar Chinese Spring (CS), and six barley chromosome disomic addition lines of wheat (2H-7H) on locomotor activity, feeding behavior, survival and development of L. migratoria...
