Three species of aphids in the genus Aphis and one in the genus Macrosiphum feed on fireweed in the Rocky Mountains of Colorado, U.S.A. These species differ in their time of colonization of fireweed, time of maximum number of colonies, feeding position on fireweed, relationships to tending ants, life table parameters, and other life history characteristics. Possible reasons for such differences among cooccurring aphids are discussed.

Abstract Musca domestica Linnaeus is an important public health pest with the ability to adapt to diverse climates. Assessment of variations in biology and life-history traits of insects along geographical gradients is important for a successful management plan in different regions. We investigated life-history traits and life table parameters of M. domestica from six different geographical regions of Punjab, Pakistan: Rahim Yar Khan (RYK), Bahawalpur (BWP), Multan (MTN), Lahore (LHR), Gujrat (GJT), and Murree (MRE). Overall, M. domestica from localities of lower latitude and elevations with higher mean temperatures completed their development faster than those from localities of higher latitude and elevations with lower mean temperatures. The immature developmental time was the longest for the MRE population that was collected from higher latitude and elevation with cooler climate, whereas the shortest for the RYK population from lower latitude with warmer climate. Pupal weights were heavier for the RYK, BWP, and MTN populations, all were from the lowest latitude and elevations with warmer climate, compared with rest of the field populations. Similarly, rate of adult eclosion, fecundity, egg hatching, longevity, and life table parameters such as intrinsic rate of population increase, mean relative growth rate, net reproductive rate, and biotic potential were significantly higher for the RYK, BWP, and MTN populations compared with the GJT, LHR, and MRE populations of M. domestica. The current results will probably be of importance when planning management of M. domestica in different geographical regions of Pakistan.

The demographic characteristics of red mite, Tetranychus bioculatus were studied through life table construction based on life history data using leaves of three ornamental host plants viz., marigold (Tagetes sp.), rose (Rosa sp.) and cosmos (Cosmos bipinnatus) in the laboratory at temperature of 20.3±0.66oC and relative humidity of 75.25±3.30%. The life cycle duration of red mite from egg to adult was shortened when feeding on marigold leaves with no significant differences in duration of life stages consuming three different hosts. The fecundity ranged from 70.6 to 109.8 eggs per female and it significantly differed among the mites live on different host plants. The host plants influenced the life table parameters of T. bioculatus showing highest innate capacity of increase (rm) of 0.24 on marigold. The marigold and cosmos favors increase mite population by 2.2 and 1.5 times, respectively, which higher than those fed on rose in the generation times (GT) of 18.22 and 19.18 days. Key words: Red mite, ornamental host plants, life history, life table. doi:10.3329/jard.v6i1.1661 J Agric Rural Dev 6(1&2), 83-90, June 2008
