Mussidia Nigrivenella

AbstractLife table studies of Mussidia nigrivenella Ragonot, a pest of maize in Benin, showed that host plant species had a significant effect on larval survival and developmental time. The maximum percentage of larvae surviving was recorded on jackbean, Canavalia ensiformis (36%) and lowest on maize (18%). Mean developmental time for larvae was longest on maize (19.8 days) and shortest on jackbean (17.2 days). The number of eggs laid was highest for females from larvae fed on jackbean (x– = 176), followed by velvetbean, Mucuna pruriens(x– = 143), and lowest for females where larvae had fed on maize (x–= 127). Longevity of ovipositing females was higher on jackbean (5.4 days) than of those from any other host plants. According to the growth index and life table statistics, jackbean was the most suitable host plant, followed by velvetbean, and maize, the least suitable. Thus, jackbeans should be recommended for use in mass rearing programmes of M.nigrivenella, e.g. as a host for parasitoids in future biological control programmes. Because of the high suitability of jack- and velvetbeans for M.nigrivenella, planting of these increasingly important cover crops should be timed in such a manner that the emergence of female moths from mature pods does not coincide with maize plants in a suitable developmental stage for oviposition and development of young M. nigrivenella larvae.

Big-eyed bugs Geocoris spp. (Lygaeidae, Hemiptera) are small insects that is found in many parts of the world. They are beneficial because they eat a multitude of insect pests in agriculture. Big-eyed bugs Geocoris spp. are insects that receive research attention in Florida and elsewhere because of the benefits that this species give to plants (Mead, 2001). Big-eyed bugs reproduce many generations in a year on weeds, perennial crops, bushes. In spring the female big-eyed bugs start laying eggs on the bud, the leaves of the host plant. Understanding the biology and the role of predator Geocoris spp. in ecosystem will provide an alternative method in sustainable agriculture development. In this short review, we discuss some convenient diets for the application of mass rearing Geocoris spp.

AbstractIn this ecological survey conducted mainly in western Tanzania between 1962 and 1969, six species of Earias were found, including two undescribed species and E. cupreoviridis (Wlk.), which is restricted to Sida spp.; E. biplaga (Wlk.) and E. insulana (Boisd.) were the only species found on cotton and were virtually restricted to Malvales. Differences in the incidence of Malvales and the Earias larvae feeding on them were noted on a research farm and on surrounding local farms as being due to different farming practices and soil types. E. biplaga was the dominant species on cotton for most of each year and its major alternative host was Waltheria indica; E. insulana was relatively more common on cotton in the dry season and was particularly common on Abutilon spp. Populations of E. biplaga increased on W. indica early in the rainy season, then dispersed onto cotton; populations on cotton could be predicted from the size of earlier populations on W. indica and subsequent rainfall.

AbstractLygus bugs (Lygus hesperus Knight) were reared in the field on cotton and alfalfa to estimate their longevity, fecundity, and survivorship. In some tests, individuals were switched from one host plant to the other at the beginning of the adult stage.Net reproductive rates (Ro) and innate capacities for increase (rm) were calculated for each of the three test populations and used as indices of host suitability. Females reared on alfalfa had greater Ro and rm values than those on cotton, while those switched from alfalfa to cotton at the adult molt had the lowest Ro value and an intermediate value of Rm.
