Abstract Given the new spread and potential damage of fall armyworm (FAW), Spodoptera frugiperda (J. E. Smith) (Lepidoptera: Noctuidae) in Asia, it has become imperative to understand development biology this invasive species on selected vegetable crops newer geographical regions. In study, we investigated ovipositional preference FAW females different host plants, under choice- non-choice tests. addition, using age-stage, two-sex life table theory, assessed performance immature individuals...

Wild tomato species exhibit natural insect resistance, yet the specific secondary metabolites and underlying mechanisms governing resistance remain unclear. Moreover, defense expression dynamically adapts to herbivory, causing significant metabolic changes species-specific metabolite accumulation. The present study aims identify resistance-related in wild accessions that influence mechanism against whitefly (Bemisia tabaci Asia II 7) leafminer (Phthorimaea absoluta). In this study,...

Bacterial wilt (BW) is one of the most economically important diseases tomato and eggplant in tropics subtropics, grafting onto resistant rootstocks can provide an alternative effective solution to manage soil-borne bacterial these crops. This study was conducted evaluate BW resistance agronomic potential newly identified accessions as for grafting. Five (VI041809A, VI041943, VI041945, VI041979A, VI041984) from World Vegetable Center were evaluated with two different fresh market cultivars...

Tomatoes are one of the predominant vegetable crops grown throughout year in Tamil Nadu, India. Their perishable nature and resource-intensive cultivation make them susceptible to biotic stress. The damage caused by invasive insect pests, bacterial wilt during rainy season, viral diseases major yield-limiting factors, farmers mostly depend on calendar-based insecticide applications for pest disease management tomatoes. desired tomato hybrids grafted onto wilt-resistant eggplant rootstocks...

The majority of plant viruses are dependent on arthropod vectors for spread between plants. Wheat streak mosaic virus (family Potyviridae, genus Tritimovirus, WSMV) is transmitted by the wheat curl mite, Aceria tosichella Keifer, and this vector cause extensive yield losses in most major (Triticum aestivum L.)-growing regions world. Many cultivars use susceptible to vector-virus complex, 10-99% have been documented. mite resistance genes identified goat grass, Aegilops tauschii (Coss)...

Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae) is one of the most economically important pests tomato worldwide. Despite its global importance, management this oligophagous pest has still been a challenging task, due to high capability develop resistance against synthetic insecticides. Given limited studies on effectiveness different bio-pesticides in India, objective research was determine pathogenicity commercial formulations Beauveria bassiana, Bacillus thuringiensis, and neem...

Tomato continues to be one of the most important crops worldwide, and protected cultivation is practiced overcome biotic abiotic stresses which plant are exposed during growth. In this study we evaluated effect colored net houses on growth, yield nutritional values, as well incidence common pests under three different light conditions: (1) (magenta), (2) conventional (white), open field conditions. A house led plants grow taller with higher lycopene content, but recorded a number whiteflies,...

International crop exchange always brings the risk of introducing pests to countries where they are not yet present. The invasive pest Tuta absoluta (Meyrick 1917), after taking just a decade (2008–2017) invade entire Africa continent, is now continuing its expansion in Asia. From first detection Turkey (2009), has extended range invasion at very high speed progression southeast part This study adopted cellular automata modelling method used successfully predict spatiotemporal T. find out if...

The Russian wheat aphid, Diruaphis noxia (Kurdjumov) (Hemiptera: Aphididae), is globally one of the most devastating pests bread wheat, Tritium aestivum L.; durum Triticum turgidum and barley, Hordeum vulgare L. Host plant resistance foundation for cereal insect pest management programs, several sources D. have been incorporated in cultivars to manage damage. emergence North American biotype 2 (RWA2) Colorado has made all known Dn genes vulnerable except Dn7 gene from rye, Secale cereale,...

El estudio se realizó bajo condiciones de invernadero (temperatura máxima: 37,1 ± 5,1 °C, temperatura mínima: 25,0 2,0 °C; humedad relativa 67,0 6,2%, 39,5 10,9%; 12: 12 h Luz: Oscuridad, régimen natural luz) en el municipio Palmira, Valle del Cauca. Se determinaron características morfológicas cada estadio desarrollo, tiempo duración, sobrevivencia, parámetros ecológicos, capacidad reproductiva, longevidad adultos y mortalidad específica por Diaphorina citri (Hemiptera: Liviidae) brotes...

Invasive tomato leaf miner, Phthorimaea absoluta causes serious damage and yield loss in production open-field protected cultivation. Use of chemical pesticides is uneconomical adversely affects humans the environment. Host-plant resistance an effective, economical eco-friendly alternative to pesticides. In this study, four wild accessions from World Vegetable Center along with one susceptible check were evaluated for their antixenosis antibiosis effects on P. absoluta. The VI037241 (Solanum...

The evolution of oviposition preference in insects is considered a key evolutionary strategy the context host-plant interaction. It hypothesized that maximize survival and fitness subsequent generations by preferring specific host plant(s), known as "preference-performance hypothesis." In this study, we tested whether adult reflects immature performance an oligophagous insect, Phthorimaea absoluta Meyrick, rapidly emerging invasive pest Asia, Africa, Europe. Based on preliminary survey...

The Russian wheat aphid, Diuraphis noxia (Kurdjumov) (Hemiptera: Aphididae), devastates and barley production on all continents except Australia. Although D. noxia–resistant cultivars exist, virulent populations exist in Asia, North America, South America that have the ability to overcome resistance. In this study, synthetic hexaploid genotypes created at International Maize Wheat Improvement Center (CIMMYT) were evaluated characterized for resistance American biotype 2 (RWA2). Fewer RWA2...

The South American tomato leaf miner, Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae), one of the most important invasive insect pests affecting production worldwide, was for first time detected in Myanmar. Preliminary surveys on pest occurrence crops Myanmar suggested presence T. Southern Shan State, but there no official survey conducted until end 2019. Therefore, this study aimed to confirm specifically observed which is largest area Myanmar, where grown under two cultivation methods,...

Several greenhouse experiments were used to measure how high levels of antibiosis resistance nymphs in two interspecific Brachiaria (brachiariagrass) hybrids affect life history parameters the spittlebugs Aeneolamia varia (F.) and Zulia carbonaria (Lallemand), most important spittlebug (Hemiptera: Cercopidae) species affecting production Colombia. The A. varia-resistant hybrid CIAT 36062, Z. carbonaria-resistant SX01NO/0102, susceptible accession 0654 compare effect all possible combinations...

The Russian wheat aphid, Diuraphis noxia (Kurdjumov) (Hemiptera: Aphididae), is an important pest in the western Great Plains of United States, where it causes hundreds millions dollars losses to barley and production through reduced yields. Experiments evaluate effect early planting resistance (Hordeum vulgare L.) on D. were conducted at Fort Collins, CO; Tribune, KS; Sidney, NE, 2007, 2008, 2009. Treatments included two dates four cultivars, noxia-resistant cultivars 'Stoneham'...

Studies on the development and reproduction of Brethesiella cf. abnormicornis (Girault) (Hymenoptera: Encyrtidae), a parasitoid Colombian fluted scale, Crypticerya multicicatrices Kondo & Unruh (Hemiptera: Monophlebidae), were conducted under laboratory conditions. The duration life cycle, adult longevity, fecundity, population parameters determined. takes about 29 d to complete single generation (from egg adult). In addition, show that one female wasp is replaced by nearly 32 females, with...

The legume pod borer (Maruca vitrata) is one of the most serious pests due to its wide host range and high damage potential. Pheromone components on M. vitrata have been previously identified, allowing research more environmentally friendly IPM tools for control. produces a three-component pheromone blend containing (E, E)-10,12-hexadecadienal (major), E)-10,12-hexadecadienol (minor), (E)-10-hexadecenal (minor).
