Lock In

Path dependence concepts, thus far, have seen little application in archaeology, but they have great potential. At a general level, these concepts provide tools for theorizing historical sequences, such as patterns of settlement on a landscape and divergent historical traditions. Potential applications include issues of historical contingency in the late Rio Grande, settlement in the Mesa Verde region, and divergent trajectories in the post-Chaco period. Specific concepts from path dependence theory, including lock-in and critical junctures, are illustrated by an analysis of the growth of Hohokam irrigation, which exhibited a path-dependent trajectory. As archaeological study of path dependence builds awareness of the importance of decision-making on the future, it contributes to difficult decision-making in today’s world.

Aim: Information on the influence of water availability during different seasons of rainfed or irrigated agriculture as it relates to insect pest population build-up in crops could assist in the development of integrated pest management. A study was therefore conducted to investigate effects of spacing, pest infestation and control on cucumber under rainfed and irrigated conditions. Place and Duration of Study: At the Teaching and Research Farm, Ekiti State University, Ado Ekiti, Nigeria during the 2016/2017 rainy and dry seasons. Methodology: The experiment was laid out using randomized complete block design (RCBD) in a split-plot arrangement in five replications, with spacing (60 x 60 cm, 60 x 90 cm and 60 x 120 cm) as the main plot treatments and the sub-plot treatments were different pest control strategies. The pest control strategies include synthetic insecticide (Lambda-cyhalothrin), botanical insecticide (Anogeissus leiocarpus) and control. Growth parameters and yield attributes were recorded. Insect pest occurrence, their build-up and percentage infestation on cucumber and the efficacy of the management strategies were monitored. Results: The results showed that yield was enhanced in irrigated system with the widest spacing of 60 x 120 cm botanical treatment interaction. Bemisia tabaci was the most prominent insect pest attacking cucumber under irrigated system. Conclusion: Other cultural control practices such as the use of trap crops with little or no financial implication should also be added to botanical pesticides as an integrated pest management tactic for effective management and control of the pest.

Insect Monitoring

One of the key-points in sustainable agriculture is to minimize the amount of pesticides inputs in agro-ecosystems increasing selectivity of active agents on target pests mainly. According to this perspective, control strategies utilising baits receive a growing interest. a spinosad-poisoned sugar-based bait, the so called GF-120 bait, utilised against diptera Tephritidae, recently appeared on the market. The toxicity of spinosad for non-target insects is demonstrated by several authors. However, the amount of pesticide applied is strongly reduced by using it with an attractive food-bait, even if field evidences on the selective attraction of this bait are missing. The aim of this paper is to evaluate the selectivity of GF-120 bait toward target and non-target insects under field conditions, focussing our attention on pollinators. Field trials were performed in a 20 years old olive orchard, where 12 baited and 12 unbaited traps were positioned for insect monitoring. The abundance of the most common orders of insects and target pest species Bactrocera oleae and Ceratitis capitata has been assessed. The main finding of this research is that many pollinators are not attracted by the bait, while target and non-target diptera are significantly attracted by the bait with the exception of Muscidae. The attraction toward a part of non-target diptera should be better explored in order to avoid negative impact on beneficial and non-target species. The need of pest control strategies safer for the environment and the wild populations of non-target organisms seems to be satisfied by the use of this bait.

Background: Resource-poor small-scale farmers often cannot afford the high prices of chemical insecticides to control pests on crops; as a result, some use botanical insecticides. Aim: The aim of the study was to document ethnobotanical pest control methods used by rural small-scale farmers to control pests of cabbage in the Eastern Cape Province of South Africa. Setting: 217 rural small-scale crop-producing farmers from 14 towns in the Amathole, Joe Gqabi, Alfred Nzo, Chris Hani and OR Tambo Districts participated in the study. Methods: Questionnaires were administered to consenting farmers between July and November in 2012, using the convenience and stratified purposive sampling techniques. Data collected were subjected to descriptive statistical analysis. Results: The majority of farmers using botanical insecticides were females above the age of 60 years. The farmers identified 23 plants, which they use in their pest control strategies against seven pests of cabbage. The annual herb Tagetes minuta L. (Asteraceae) was cited as the most commonly used herb by 47% of the respondents, followed by Chenopodium ambrosioides L. (Chenopodiceae), Aloe ferox Mills. (Asphodelaceae) and Nicotiana tabacum L. (Solanaceae). Various plant parts were used in combinations or alone in the preparation of formulations mainly against aphids, cutworms and the diamondback moth. Conclusion: The plants, plant parts, combinations and formulations used by farmers in their cabbage pest control strategies need to be scientifically authenticated for efficacy.

Impulsive Release

We propose an impulsive biological pest control of the sugarcane borer (Diatraea saccharalis) by its egg parasitoidTrichogramma galloibased on a mathematical model in which the sugarcane borer is represented by the egg and larval stages, and the parasitoid is considered in terms of the parasitized eggs. By using the Floquet theory and the small amplitude perturbation method, we show that there exists a globally asymptotically stable pest-eradication periodic solution when some conditions hold. The numerical simulations show that the impulsive release of parasitoids provides reliable strategies of the biological pest control of the sugarcane borer.

Many perpetrators of sexual violence are themselves victims of similar crimes. Such “complex victims” do not fit neatly into the dichotomous categories of victim and perpetrator essential to the functioning of the adversarial criminal-legal system. How anti-rape activists attempt to incorporate complex victims into their work illustrates challenges they experience when wrestling with the carceral state more broadly. In this article, I draw on 32 months of participant observation and 40 in-depth interviews to show how organizational conditions—departmental silos and physical infrastructure—prevent activists’ treatment of complex victims. Building on the concept of path dependence from organization theory, I argue that carceral understandings of harm become “locked-in” despite activists’ anti-carceral attitudes. This article identifies barriers to the treatment of complex victims, further explains feminist activists’ simultaneously contentious and coalitional relationship with the carceral state, and introduces the concept of carceral lock-in to help understand impediments to justice alternatives.
