“…Recently, a series of biorational techniques such as trap crops, modified orchard design and the use of behaviormodifying chemicals have been proposed (see Aluja and Rull 2009 and references therein). In spite of these alternatives, a large share of small-scale fruit growers in the Neotropics still rely on calendar-based applications of broad-spectrum insecticides such as malathion sprayed singly or in combination with hydrolyzed protein used as a bait (Aluja 1994;Moreno and Mangan 2002;Mangan and Moreno 2007) or more recently, the bacteriaderived insecticide spinosad (McQuate et al 2005). Despite their effectiveness, resistance (Wang et al 2005;Hsu and Feng 2006), negative impact on natural enemies or on other non-target organisms (Stark et al 2004), as well as water and soil pollution (Favari et al 2002;Murray et al 2010), and deleterious effects on human health (Band et al 2011;Hernández et al 2013;Kjeldsen et al 2013), call for more environmentally-friendly alternatives such as the one proposed here.…”

Tropical trees can provide various ecological services to adjacent agricultural environments, including maintaining and amplifying the numbers of beneficial insects. In Mexico, certain tree species harbor a diverse guild of hymenopteran parasitoids that attack pest fruit flies (Diptera: Tephritidae) and are at the same time sources of valuable hardwood timber. Indigenous trees and their associated fauna are slowly disappearing due to forest clearance and the expansion of crop monocultures. Here we explore the relationship among pest and non-pest fruit flies, their fruit-hosts and parasitoids in the context of mango orchards and surrounding patches of uncultivated vegetation and propose a novel mechanism to use these associations in favor of conservation purposes and pest management. Trees of conservation biological control interest are classified as: (1) parasitoid multiplier plants, species that serve as alternate hosts for key fruit fly pests when their commercial hosts are not available, but in which they are unusually vulnerable to parasitism; (2) parasitoid reservoir plants, native or introduced trees in whose fruits non-pest fruit flies serve as hosts to generalist parasitoids that are able to attack pest tephritids in other species of commercially grown fruit; and (3) -014-0636-3 introduced species that are not economically important locally, but which harbor fruit flies that would be pests in other circumstances and that serve as hosts for parasitoids of the important pests in the vicinity. Protection, multiplication and dissemination of such tree species has the potential to increase the number of naturally produced fruit fly parasitoids and could assist in the management of tephritid pests in areas where destruction of forests has impoverished the historical sources of fruit fly natural enemies. Tropical forest conservation may help resource-poor farmers reduce crop losses, increase biodiversity within fruit-growing regions and conserve native forests for both conservation purposes and commercial use of native hardwoods.123 Biodivers Conserv (2014) 23:831-853 DOI 10.1007/s10531

“…Because of their peculiar life history, most of the efforts in fruit fly control and eradication have focused on mature adults, e.g., bait traps (Vargas et al, 2003;McQuate et al, 2005), methyl eugenol utilizing (Cunningham, 1989;Shelly et al, 2004) and sterile insect technique (Wong et al, 1992;Hendrichs et al, 2002). However, some attention has been paid to the possibility of fly control by targeting late-instar larvae and pupae.…”

Estimates of pupation depth and survival of the Oriental fruit fly, Bactrocera dorsalis (Hendel), are important for optimizing soil control and for better understanding its natural mortality in the agricultural system of Guangzhou, China. Late third-instar larvae were placed in soils having relative moistures of 0-100% for pupation. No pupae were found on the surface at soil moistures of 0-70%. Instead, more than 50% of the larvae pupated on the surface at soil moistures of 80, 90, and 100%. Most of the larvae preferred to pupate in less than 4 cm of the soils, while relatively few larvae moved more than 4 cm when the soils received too little water or too much water. The survival rate of pupae at 70% moisture level was low, and the pupae were unable to survive at soil moistures of 0, 80, 90, and 100%, while emergence rates exceeded 90% at the conditions of 10-60% moisture levels. Moreover, soil moistures had an influence on the average time to emergence (average time between the larvae release and the emergence of adults). Adult flies at 30% moisture level emerged earlier than those at the other moisture levels, whereas the average time to emergence at 70% moisture level was the longest.

“…Roots of D. elliptica contain many compounds, such as rotenoids, isoflavones, ceramides and rotenoids (Wu et al, 2012). LC 50 values reported in this work are higher compared to values reported from other studies (see Mangan, 2009;McQuate et al, 2005;Wang et al, 2013;Yee and Chapman, 2013;Zhang et al, 2015). The concentration and dose of toxicants used to kill 50% of a population of fruit flies are variable depending on species and insecticidal compound.…”
