Plants release a variety of volatile organic compounds that play multiple roles in the interactions with other plants and animals. Natural enemies plant-feeding insects use these volatiles as cues to find their prey or host. Here, we report differences between blends tomato infested whitefly Bemisia tabaci borer Tuta absoluta. We compared emission of: (1) clean plants; (2) T. absoluta larvae; (3) B. adults, nymphs, eggs. A total 80 were recorded which 10 occurred consistently only headspace...
The tomato leafminer Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae) represents a global threat to commercial (Solanum lycopersicum L.) production, both in open field and greenhouse. Native South America, it spread over the Mediterranean Basin, Europe, Africa part of Asia only 12 years, currently is reported 80 countries. Biological control one options for its large number natural enemies has been association with pest, areas origin introduction. egg parasitoid Trichogramma pretiosum,...
This study evaluated the parasitoid-aphid-plant associations in Brazil with objective of developing a useful research database for further studies aphid parasitoid ecology and management. The original material was obtained from collections made Paraná, Rio Grande do Sul, Minas Gerais, São Paulo states. published information on Aphidiinae is revised. general features target fauna Central South America summarized promising biological control programs some species discussed.
Tuta absoluta (Meyrick) has quickly developed into a significant tomato pest worldwide. While the recently found mirid predators Macrolophus basicornis (Stal), Engytatus varians (Distant) and Campyloneuropsis infumatus (Carvalho) of this are able to establish reproduce on tomato, biological knowledge these mirids is still limited. Here we describe functional response three T. when offered range prey densities (four, eight, 16, 32, 64, 128 256 eggs) during 24 h period inside cylindrical...
A suitable host provides, at least, the minimum nutritional and physiological conditions for development of immature stages a parasitoid.Host quality may influence developmental time, mortality rate, longevity fecundity parasitoids.This work evaluates suitability Aphis gossypii Glover, Brevicoryne brassicae (Linné), Myzus persicae (Sulzer), Rhopalosiphum maidis (Fitch) Schizaphis graminum (Rondani) as hosts Aphidius colemani Viereck.Twenty second-instar nymphs each aphid species were exposed...
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...
Generalist predators are capable of consuming different types prey, and as each prey may have distinct nutritional values, a impact on the biology predator. Therefore, aim this study was to determine how consumption influences certain biological characteristics predatory capacity Orius insidiosus (Say). The investigation performed in climatic chamber at 25 ±1 ºC, RH 70 ± 10% fotophase 12. Eggs Anagasta kuehniella (Zeller), adults Caliothrips phaseoli (Hood) nymphs Aphis gossypii Glover were...
Temperature is a key abiotic factor influencing the development and reproduction of aphids. The effect temperature on three aphid species Aulacorthum solani (Kaltenbach), Macrosiphum euphorbiae (Thomas) Uroleucon ambrosiae (Aphididae, Macrosiphini) has been investigated fertility life tables were determined. Nymphs reared in climatic chambers at temperatures 16, 19, 22, 25, 28 ± 1ºC, RH 70 10% 12 h photophase. Female adult aphids developed these then used experiments which pre-reproductive...
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...
The predators Macrolophus basicornis (Stal), Engytatus varians (Distant) and Campyloneuropsis infumatus (Carvalho) consume large numbers of tomato pests such as Bemisia tabaci (Gennadius) Tuta absoluta (Meyrick). However, they are zoophytophagous feed on plant parts well. We evaluated the type effect injury caused by nymphs adults these mirids seedlings fruit in absence prey. For each mirid species, were exposed to groups 20 or for 72 h, fruits 48 h four adults. Type number stems, petioles...
Orius species are important biological control agents of thrips in protected crops. Rearing conditions mass production facilities may affect their performance the crop when searching for target prey. The aim this study was to evaluate and compare search behaviour orientation towards prey two species, O. laevigatus (Fieber) insidiosus (Say) that have been reared laboratory under different conditions, with wild (field-collected) individuals. Adult predator females were placed a Y-tube...
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...
A biologia do percevejo predador Orius insidiosus (Say), utilizando como alimento, adultos de Caliothrips phaseoli (Hood), foi estudada em câmara climática com temperatura 25±1°C, 70±10 % UR e 12h fotofase. O período desenvolvimento ninfal 10,2 dias, não apresentando diferença significativa para machos fêmeas. duração estágio 1,9, 1,7, 1,4, 1,8 3,1 dias o 1º, 2º, 3º, 4º 5º ínstares, respectivamente. viabilidade 69,0%, sendo que a maior mortalidade ocorreu no 2º ínstar (16,0%). O. predou 73,7...
The objective of the present study was to estimate rates parasitism Lysiphlebus testaceipes (Cresson) on Schizaphis graminum (Rond.) and Aphis gossypii Glover under choice no-choice condition tests. experiments were carried out in a controlled environmental chamber at 25±1ºC temperature, 70±10% RH, 12h photophase. Second third instar aphid nymphs used as hosts for each colony one less than day old L. female used. previously mated oviposition inexperienced remained contact with 24 h. In test...
