Digital Survey

<p>The objective of this work was to determine the impact of COVID-19 on productive activities of farmers and extensionist, and the level of application of Integrated Pest Management (IPM) in urban agriculture in Xochimilco, Milpa Alta, Tláhuac, Tlalpan, Magdalena Contreras and Cuajimalpa at Mexico City, a metropolitan area with a high SARS-CoV-2 positive cases. In 2020, a digital survey was applied to a total of 108 farmers and extensionists during the first COVID-19 epidemic wave. The sanitary emergency reduced the continuity of the extension service. However, this was carried out with digital technologies including photographs submitted by WhatsApp for pest diagnosis purposes. During the maximum COVID-19 peak (July, 2020), only 14% of farmers declined to sowing the summer fall season 2020. The majority established corn and, to a lesser extent, vegetables in mixed topologies. However, the activity of agricultural workers was reduced to 50%. Up to 75% of farmers reported losses of 20% derived from the epidemic. The major pest control strategy was mechanical, mainly for preventive purposes (67%) followed by chemical control (52%), biological at both preventive (8%) and curative (25%) levels, and the combination of more than one strategy in less than 10%. The data indicate an intuitive understanding of the IPM benefit, although the farmer is unaware of its principles. Faced with the growing demand for fresh, quality and safe food as a COVID-19 preventive strategy, urban agriculture has great development prospects by supplying local markets without transport problems caused by regional and global contingencies such as that caused by SARS[1]CoV-2. However, public and institutional policies of great vision are required. This work recognizes the work of farmers, as well as extensionists in favor of food security.</p>

The Impact

REDCAHOR is the Spanish acronym for “Central American Vegetable Network.” Vegetables have traditionally been an important source of nutrients and vitamins in the diet in Central America. Vegetable production in this region is now changing as local consumers are demanding increased diversity and quality and international markets are expanding with “non-traditional” vegetable exports. The present restraints to expanded research and production of vegetables in the region include i) need for cultivars with increased insect and disease resistance, ii) poor and excessive use of pesticides, and iii) inadequate postharvest technology. In addition, there are few vegetable researchers in the region and response to their activities have not been coordinated. The goal of REDCAHOR is to develop a regional network of national institutions that can prioritize agendas and cooperate to maximize the impact of available resources. Establishment of a system of regional trials and cooperative regional programs in integrated pest management and plant breeding are currently under development. A series of regional workshops are planned, including integrated pest management, maintenance and use of genetic resources, organic production, and greenhouse production. In addition, REDCAHOR, in collaboration with the Escuela Agricola Panamerica in Honduras, will offer regional short-course training in vegetable breeding and genetics as well as vegetable production and management, including integrated pest management.

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.

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).

The Impact

This paper develops a methodology to calculate the impact of integrated pest management (IPM) on pesticide use, yields, and farm profits. The methodology is applied to the IPM adoption among fresh market tomato producers in eight states. The method is of general applicability. It accounts for self-selectivity and simultaneity, and the pesticide demand and yield equations are theoretically consistent with a profit function. The results support the notion that fresh market tomato growers who adopt IPM for insects and diseases apply significantly less insecticides and fungicides, respectively, than do those who do not adopt IPM; IPM adoption has an insignificant effect on yields and a small effect on profits.

The Impact

The impact and sustainability of two interventions that have been formulated to introduce integrated pest management (IPM) into rice and maize crops in Southwestern China, Laos, and Myanmar between 2011 and 2016, and were assessed at the end of 2017. From 22 Trichogramma rearing facilities established during the interventions, 11 were still producing substantial quantities of biocontrol agents 1.5 years after project support had ended, while seven had stopped operations completely, and four were doing stock rearing only. Through the implementation of biological control-based IPM, slightly higher yields were achieved in maize and rice (4–10%), when compared to control farmers, but the difference was not statistically significant. However, the use of pesticides nearly halved when farmers started using Trichogramma egg-cards as a biological control agent. Support from either public or private institutions was found to be important for ensuring the sustainability of Trichogramma rearing facilities. Many of the suggested IPM measures were not adopted by smallholder farmers, indicating that the positive impacts of the interventions mostly resulted from the application of Trichogramma biological control agents. The following assessment suggests that further promotion of IPM adoption among farmers is needed to upscale the already positive effects of interventions that facilitate reductions in synthetic pesticide use, and the effects on sustainable agricultural production of rice and maize in the target area more generally.

The Impact

There is a large suite of insects that attack anthropogenic agricultural goods after harvest. Proper sanitation programs for food facilities are now recognized as the foundation of good integrated pest management (IPM) programs for stored products throughout the post-harvest supply chain. While good sanitation programs are generally thought to reduce the abundance and diversity of insects, there has been less appreciation of the manifold ways that sanitation interacts with a range of other IPM tactics to modulate their efficacy. Here, we review the literature on how the effectiveness of chemical, physical/cultural, biological, and behaviorally-based control tactics varies with changes in sanitation. In addition, we discuss how sanitation may affect ongoing pheromone- and kairomone-based monitoring programs. Where possible, we quantitatively compile and analyze the impact of sanitation on the fold-change in the efficacy of IPM tactics. We found that decreased sanitation negatively affected the efficacy of most tactics examined, with a mean 1.3–17-fold decrease in efficacy under poorer sanitation compared to better sanitation. Sanitation had neutral or mixed impacts on a few tactics as well. Overall, the literature suggests that sanitation should be of the utmost importance for food facility managers concerned about the efficacy of a wide range of management tactics.

The Impact

Achieving adoption of integrated pest management (IPM) practices by professional landscape managers is a common goal of university research and extension personnel, governmental and regulatory agencies, industry, and the public. IPM is developed and promoted through cooperation of university, state, and industry groups in research and educational programs. Publications and educational events are major means of promoting IPM to landscape professionals. While large theater-style seminars may provide the advantage of reaching as many as 500 people at one time, landscape clientele have shown favor for the smallgroup, hands-on type of seminar for application technology and IPM methodologies. The impact of research and educational programs on IPM adoption tends to be variable, depending on the pest, the potential for effective control, the control practices to be undertaken, and economic consequences. Adoption of several biological control programs has been indicated. The pesticide-use data collected from 1992 to 1994 indicate trends in reduced use of some pesticides and shifts to less toxic materials. Unfortunately, these data do not account for variability in pest activity from year to year, and not all pesticide applicators are reporting. Pressure from the public to control pests while minimizing the use of pesticides also indicates adoption of IPM. Additional evaluations are necessary to assess adoption of current and future IPM programs.
