Abstract The tomato borer T uta absoluta , native to western South America, is an extremely devastating pest in crops most of Europe and Africa North the Sahel, causes yield losses up 100% decreases fruit quality open field greenhouse if control methods are not applied. In Brazil two other important lepidopteran pests – N eoleucinodes elegantalis H elicoverpa zea occur tomato, as well thrips, whiteflies aphids. For these pests, frequent applications pesticides 5 times per week needed,...
Ecologists study how populations are regulated, while scientists studying biological pest control apply population regulation processes to reduce numbers of harmful organisms: an organism (a natural enemy) is used the density another pest). Finding effective agent among tens hundreds enemies a daunting task. Evaluation criteria help in first selection remove clearly ineffective or risky species from list candidates. Next, we propose use aggregate evaluation criterion, kill rate, compare...
Orius insidiosus is a generalist predator for which diet influences important biological traits like reproduction and predation. We tested the effects of different diets alone or in combination on reproduction, longevity predation capacity this predator. The were: no food (control); pollen; Frankliniella occidentalis (Pergande) nymphs adults; F. adults Anagasta kuehniella (Zeller) eggs; A. eggs eggs, pollen. pre-oviposition period was shortest when consisted pollen prey (A. and/or...
Tuta absoluta (Meyrick; Lepidoptera: Gelechiidae) is a key pest of tomato and quickly spreading over the world. We conducted an experiment aimed at evaluating control capacity risk for plant damage three Neotropical mirid species, Campyloneuropsis infumatus (Carvalho; Hemiptera: Miridae), Engytatus varians (Distant; Miridae) Macrolophus basicornis (Stal; on T. infested plants in large cages experimental greenhouse. During successive periods 9 wk each, we followed population development...
Tuta absoluta (Meyrick), a key pest of tomato, is quickly spreading over the world and biological control considered as one options. Worldwide more than 160 species natural enemies are associated with this pest, an important challenge to find effective biocontrol agent from pool candidate species. Evaluation criteria for agents presented, advantages they offer separating potentially useful less promising ones. Next, aggregate parameter ranking proposed: kill rate km. We explain why...
During the past decade, use of predatory mirids alone or combined with releases egg parasitoids genus Trichogramma have been tested in Europe for biological control worldwide invasive pest, Tuta absoluta (Meyrick). Here, we evaluated this pest by release Neotropical mirid Macrolophus basicornis (Stal), Neotropic/Nearctic parasitoid pretiosum Riley, and predator parasitoid. Tests were conducted greenhouse compartments during summer fall season. Each compartment contained 10 tomato plants...
Knowledge of the optimal temperatures for development and survival biological control agents is essential efficient mass-rearing introduction natural enemies in augmentative programs.We studied effect constant alternating on immature stages sex ratio at emergence adults Nearctic generalist predator Geocoris punctipes (Say).We also determined its thermal requirements.They were reared climatic chambers (21/11°C, 24/18°C, 27/21°C 30/26°C ± 1°C) (16.8°C, 21.5°C, 24.5°C 28.3°C 1°C), RH 70 10% a...
Abstract The heteropteran predator Geocoris punctipes (Say) has been used in augmentative biological control since 2000 to Lepidoptera. However, surprisingly, few data are available about the influence of temperature on its population development, which is key importance plan number and moment releases obtain sufficient pest reduction. objective this study was evaluate daily total fecundity, longevity life table parameters (m x , l r m R, λ T TD ) G. at constant (16.8°C, 21.5°C, 24.5°C...
Abstract Biological control, which uses natural enemies to reduce pest populations, is a non-polluting powerful method manage impacts of (invasive) pests. Currently, polyphagous mirid predators are increasingly used in commercial, augmentative biological control. Information about their foraging behaviour essential, especially if one intends use several for control or more pests crop, detect negative intraguild effects occur. We studied case predation (IGP) involving predator, Macrolophus...
