  • toxicity of pesticides used in citrus to Aprostocetus vaquitarum hymenoptera eulophidae an egg parasitoid of diaprepes abbreviatus coleoptera curculionidae
    Florida Entomologist, 2006
    Co-Authors: Bryan J Ulmer, Stephen L Lapointe, Jorge E Pena, Rita E. Duncan
    Abstract:

    Abstract Twelve pesticides used in citrus were tested for their contact toxicity to Aprostocetus vaquitarum Wolcott (Hymenoptera: Eulophidae) a parasitoid of Diaprepes abbreviatus (L.) (Coleoptera: Curculionidae). Sevin® 80 WSP, Malathion 5 EC, and Imidan® 70 WSB resulted in the most rapid death of A. vaquitarum adults. Admire® 2F, Danitol® 2.4EC, and Surround® WP were also very detrimental. Kocide® 101 WP, Citrus Soluble Oil, Micromite® 80 WGS, Acramite® 50 WS, Micromite® 80 WGS + Citrus Soluble Oil, Aliette WDG, and Agrimek® 0.15 EC + Citrus Soluble Oil were slightly to non-toxic to A. vaquitarum. The relative toxicity of the pesticides was consistent up to four weeks after application. Significantly fewer adult A. vaquitarum emerged from D. abbreviatus eggs laid on foliage treated in the field with Sevin® XLR and Imidan® 70 WSB than emerged from the water treated control. Field residues of Sevin® XLR remained toxic for seven days while the effects of Imidan® 70 WSB were no longer significant after one ...

  • Successful oviposition and reproductive biology of Aprostocetus vaquitarum (Hymenoptera: Eulophidae): A predator of Diaprepes abbreviatus (Coleoptera: Curculionidae)
    Biological Control, 2005
    Co-Authors: J. A. Jacas, J. E. Peña, Rita E. Duncan
    Abstract:

    Abstract Aprostocetus vaquitarum (Wolcott) causes 78–91 percent mortality to eggs of Diaprepes abbreviatus (L.), under field conditions in southern Florida. In the laboratory, A. vaquitarum was reared on D. abbreviatus eggs at 25 °C, a photoperiod of 12:12 (L:D) and with abundant hosts, A. vaquitarum adult females lived around 15 days. Oviposition was significantly affected by the age of the host egg mass. Egg masses aged 0- to 3-day-old were accepted significantly better than those aged 4–6 days. The mean number of eggs deposited per female was around 53, with extreme values of 124 and 19 eggs per female. Using these data in combination with the sex ratio observed in the field (0.16) and the duration of the preimaginal stages, r m (0.168–0142 day −1 ), T (22.39–22.89 days), and R 0 (43.03–25.81 females per female) were calculated.

  • Tritrophic interactions in sorghum, midge (Stenodiplosis sorghicola) and its parasitoid (Aprostocetus spp.)
    'Elsevier BV', 1998
    Co-Authors: Nwanze K F, Kausalya K G, Reddy Y V R, Nwilene F E, Reddy D D R
    Abstract:

    Studies were conducted on tritrophic interactions involving sorghum genotypes, Stenodiplosis sorghicola and the predominant parasitoids (Aprostocetus spp.) in Patancheru, Andhra Pradesh, India, using three midge resistant (ICSV 745, ICSV 89058 and IS 10712) and three susceptible (Swarna, CSH 9 and ICSV 112) genotypes during the post-rainy (1992/93) and rainy (1993) seasons. A. coimbatorensis, the predominant parasitoid during post-rainy season, preferred mid-late midge larvae for parasitization, while A. gala, which was predominant during the rainy season, preferred early-mid larval stages. Variations in the preference of A. coimbatorensis and A. gala for the developmental stage of their host larvae indicated good prospects for the biological control of sorghum midge populations. There were significant differences in parasitization level of midge by Aprostocetus spp. between resistant and susceptible sorghum genotypes, and season. Higher parasitization was observed on susceptible genotypes than on resistant ones during both post-rainy and rainy seasons. However, the level of parasitization was greater in post-rainy than in rainy seasons. There was also evidence of higher midge infestation in rainy than in post-rainy seasons. Susceptible genotypes attracted more parasitoids because of high levels of midge infestations. Low parasitoid density in midge resistant sorghum under glasshouse and field conditions was associated with low midge infestations in these genotypes. However, parasitoids were always associated with their host in spite of low midge densities in resistant genotypes. The present study revealed that the interaction between host plant resistance and parasitoids of sorghum midge would thus be synergistic and complementary and could result in successful integration of these two important pest management tactics

  • Emergence pattern of sorghum midge and its major parasitoids on midge-resistant and susceptible genotypes
    'Informa UK Limited', 1997
    Co-Authors: Kausalya K G, Nwanze K F, Reddy Y V R, Nwilene F E, Reddy D D R
    Abstract:

    Studies were conducted on the species composition of parasitoids of Stenodiplosis sorghicola, emergence pattern and level of parasitism. The studies were carried out in Andhra Pradesh, India, with three midge-resistant (ICSV 745, ICSV 89058 and IS 10712) and three susceptible (Swarna, CSH 9 and ICSV 112) sorghum genotypes during the 1992-93 post-rainy and 1993 rainy seasons. The species of parasitoids collected were Aprostocetus gala, A. coimbatorensis and Eupelmus spp. The species composition varied with the season, but was unaffected by varietal resistance and susceptibility to the midge. Although both species of Aprostocetus were present in rainy and post-rainy seasons, A. gala was predominant during the rainy season whereas A. Coimbatorensis was predominant in the post-rainy season. There was no significant difference in the pattern of parasitoid emergence or the level of midge parasitization between resistant and susceptible genotypes. These results indicate that resistance to midge in the genotypes studied was not antagonistic to parasitoid activity, and that there is potential to interface biological control with host-plant resistance in the management of this insect

  • Insect- Host Plant-Parasitoid Interactions : SORGHUM MIDGE Contarlnla sorghicola (Coqulllett)
    1994
    Co-Authors: Kausalya K G
    Abstract:

    Three resistant (ICSV 745, ICSV 89058 and IS 10712) and three susceptible (Swarna, CSH 9 and ICSV 112) sorghum genotypes were sown on three dates each during the rainy (6, 15 and 30 Jul in rainy season 1992 and 2, 19 Jul and 6 Aug in rainy season 1993) and post-rainy (29 Oct, 13 Nov and 1 Dec 1992) seasons of 1992193. A modified headcage was developed for easy and precise collection of emerging insects. The species composition of natural enemies included three larval parasitoids (Aprostocetus sp., Eupelmus sp. and Apanfeles sp.) and one predator (Orius sp.). Parasitoid emergence commenced 1 - 3 weeks after initiation of midge emergence. The population dynamics of Aprostocetus sp, was similar in susceptible and resistant genotypes. Aprostocetus sp, activity was higher in the first and third sowing dates than in the second and greater numbers were recovered from susceptible than from resistant genotypes. The extent of parasitization of midge larvae did not follow a definite pattern with resistance or susceptibility of the host plant to midge. The lowest levels of parasitization were recorded from midge resistant ICSV 745. Studies on the tritrophic interactions indicated variations in preference for host stage for parasitization and development in rainy and post-rainy season
