Population Suppression

Intercropping of aromatic plants provides an environmentally benign route to reducing pest damage in agroecosystems. However, the effect of intercropping on natural enemies, another element which may be vital to the success of an integrated pest management approach, varies in different intercropping systems. Rosemary, Rosmarinus officinalis L. (Lamiaceae), has been reported to be repellent to many insect species. In this study, the impact of sweet pepper/rosemary intercropping on pest population suppression was evaluated under greenhouse conditions and the effect of rosemary intercropping on natural enemy population dynamics was investigated. The results showed that intercropping rosemary with sweet pepper significantly reduced the population densities of three major pest species on sweet pepper, Frankliniella intonsa, Myzus persicae, and Bemisia tabaci, but did not affect the population densities of their natural enemies, the predatory bug, Orius sauteri, or parasitoid, Encarsia formosa. Significant pest population suppression with no adverse effect on released natural enemy populations in the sweet pepper/rosemary intercropping system suggests this could be an approach for integrated pest management of greenhouse-cultivated sweet pepper. Our results highlight the potential of the integration of alternative pest control strategies to optimize sustainable pest control.

AbstractThree species of ambrosia beetles (Trypodendron lineatum (Olivier), Gnathotrichus sulcatus (LeConte), and G. retusus (LeConte) (Coleoptera: Curculionidae: Scolytinae)) have been estimated to cause annual losses of $95–$189 million in degrade of logs and lumber on the British Columbia coast, in Canada. A consultant-run semiochemical-based integrated pest management programme was implemented in 1982 against these beetles, following fulfilment of four prerequisites: (1) presence of receptive potential clients, (2) availability of semiochemical lures, (3) invention of an operational trap, and (4) proof of concept of mass trapping technology. The programme is based on two broad strategies: maintain the problem at a tolerable level and, if necessary, reduce the problem to a tolerable level. One measure of effectiveness over 12 years of mass trapping at a dryland sort near Sooke, on Vancouver Island, British Columbia, was 16.4 million beetles trapped and an estimated five to one benefit-to-cost ratio. Despite success, several factors have conspired to reduce the programme from 50 sites serviced in early years to 7 in 2018. Timber companies in British Columbia are currently showing renewed interest and are taking steps to incorporate the integrated pest management programme as a formal component of their overall operations.

The objective of this work was to evaluate the impact of integrated pest management (IPM) in the productivity of the tomato and in the populations of leafminers, fruit borers, and natural enemies in tomato crops. The treatments were calendar (spraying twice weekly with insecticides and fungicides), IPM (spraying when action thresholds were achieved), and control (no pesticide was applied). IPM was the most efficient system of pest control due to presenting similar productivity and 65.6% less pesticide applications than in the calendar. The attack of Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae) and Liriomyza spp. (Diptera: Agromyzidae) to the leaves only achieved the action threshold in the final phase of the cultivation. The main fruit borer was Neoleucinoides elegantalis (Guen.) (Lepidoptera: Crambidae), followed by T. absoluta and Spodoptera eridania (Cr.) (Lepidoptera: Noctuidae). The natural enemy populations were severely reduced by excessive pesticide applications. Predators were more abundant than parasitoids. The most abundant predators were Araneidae, Anthicus sp. (Coleoptera: Anthicidae), Cycloneda sanguinea larva (L.) (Coleoptera: Coccinellidae), Staphylinidae adults (Coleoptera), Orius sp. and Xylocoris sp. (Hemiptera: Anthocoridae), Formicidae (Hymenoptera), and Phlaeothripidae (Thysanoptera). The most abundant parasitoids were Hymenoptera of the families Eulophidae, Braconidae (Bracon sp. and Chelonus sp.), Trichogrammatidae [Trichogramma pretiosum (Riley)] and Bethylidae (Goniozus nigrifemur Ashmead), besides Tachinidae (Diptera).

Randomized Block Design

Aim: Some genotypes of mothbean were screened for their comparative preference against jassids, whiteflies and thrips. Materials and Methods: The experiment was laid out during Kharif season in Randomized Block Design with three Replications. Ten genotypes (viz., RMO-225, RMO-40, RMO-423, RMO-435, RMO-257, RMO-25, RMO-141, RMO-20-36, RMO-04-01-28 and RMO-28-80) were screened against major sucking insect pests which were replicated thrice. Observations: The observations were recorded after two weeks of sowing at weekly intervals after two weeks of sowing. The pest populations were recorded on five randomly selected and tagged plants per plot in early hours when insect have minimum activity. Results: The data revealed that none of the genotypes ware found free from sucking insect pest attack. On the basis of peak population, the genotypes RMO-25 and RMO-141 were categorized as least preferred to jassids, whiteflies and thrips, whereas, RMO-435, RMO-225 and RMO-04-01-28 as highly preferred to jassids and whiteflies and RMO-435, RMO-225 and RMO-257 as highly resistant to thrips. Conclusion: It is well known that certain genotypes of crops are less attacked by a specific insect-pest than others because of natural resistance. In the integrated pest management programme, growing of varieties (RMO-25 and RMO-141) with less preference to sucking insect-pests is one of the most important tools without additional cost.

En el campo se observaron daños ocasionados por una larva de Chrysopidae (Neuroptera) sobre pupas centinelas de<em>D. inedulis</em>. Se realizaron experimentos con un cebo tóxico de origen natural a base de <em>Saccharopolyspora spinosa </em>en los municipios de Palmira y Toro, en el departamento del Valle del Cauca, destacándose como una nueva alternativa para el control de <em>D. inedulis </em>en maracuyá amarillo, ya que en las dos localidades mantuvo los niveles de daño por debajo del manejo convencional del agricultor y el testigo absoluto. Se provee una lista de enemigos naturales de <em>D. inedulis </em>tomada mediante muestreos de botones florales de maracuyá, uso de pupas centinelas, e información en la literatura científica. Para el control de la mosca del botón floral del maracuyá, <em>D. inedulis</em>, se propone una estrategia de manejo integrado de plagas que le permitirán al productor mantener las poblaciones de <em>D. inedulis </em>reguladas con diferentes herramientas, i.e., enemigos naturales que se pueden incorporar en diferentes etapas de la fenología de <em>D. inedulis</em>, uso de cebos tóxicos de baja toxicidad, recolección de botones con síntomas de daño, y monitoreo con el uso de trampas McPhail cebadas con proteína hidrolizada, interviniendo en diferentes estados de desarrollo, cortando ciclos y disminuyendo así futuras generaciones del insecto. </p><p> </p><p><strong>Integrated pest management as a strategy to control the passionfruit flower-bud fly, <em>Dasiops inedulis</em>Steyskal (Diptera: Lonchaeidae)</strong></p><span> Four parasitoids of the passion fruit flower bud fly, </span><em>Dasiops inedulis </em><span>Steyskal (Diptera: Lonchaeidae) were collected in the present study, i.e., a larva-pupa type parasitoid, </span><em>Utetes anastrephae </em><span>(Viereck) (Hymenoptera: Braconidae), and three pupal parasitoids, namely </span><em>Pachycrepoideus vindemmiae</em><span>Rondani, </span><em>Spalangia </em><span>sp. (Hymenoptera: Pteromalidae) and</span><em>Aganaspis </em><span>sp. (Hymenoptera: Figitidae).

ABSTRACT: The entomopathogen Bacillus thuringiensis (Bt) is widely used as one of the ingredients in pest control formulations, but researches conducted on its effect on non-target organisms are still in the nascent stage. This investigation aimed to uncover if Bt treated with Tenebrio molitor (Coleoptera: Tenebrionidae) larvae and pupae could affect the biological variables of Podisus nigrispinus (Hemiptera: Pentatomidae) and Palmistichus elaeisis (Hymenoptera: Eulophidae), all of which established natural enemies of leaf defoliator caterpillars in the eucalyptus culture. Larvae of T. molitor were fed on wheat bran containing different concentrations of B. thuringiensis (0.00; 0.25; 0.50; 1.00; 2.00 and 4.00 g Agree/kg bran). When the larvae attained size of about 2 cm, they were used as prey for P. nigrispinus (Bioassay I), and their pupae used as hosts for P. elaeisis (Bioassay II). Only the biological variables oviposition period and egg numbers by posture of the predator P. nigrispinus were altered. The biological variables of P. elaeisis were not altered, since it was possible to use these control methods within the integrated pest management.
