The adverse effects of molluscicides applied for the control of the invasive apple snails, Pomacea spp., have led to the search for eco-based cultural, mechanical and biological control techniques. Therefore, a field study on the relative effectiveness of locally available and cost effective...

This proceedings contains papers addressing the challenges of biological and integrated pest management strategies against the main pests and diseases of protected vegetable and ornamental crops. Topics discussed include the use of predators, symbionts, old natural enemies, entomopathogens,...

Occasionally, exotic plant introductions lead to the emergence of an invasive insect within its native geographical range. Such emergence could be explained by a pre-adaptation of the insect to break through the defences of the new encountered host. We investigated the fitness responses of two New...

Rotenone, a naturally occurring ketone, is widely employed for the management of invasive fish species. The use of rotenone poses serious challenges to conservation practitioners due to its impacts on non-target organisms including amphibians and macroinvertebrates. Using laboratory studies, we...

Over the past several decades, there has been a resurgence of interest in industrial hemp (Cannabis sativa L., Cannabaceae) cultivation. Besides fibre, seeds and oil, hemp contains high quantity of essential oil (EO). Hop (Humulus lupulus L., Cannabaceae) is a high-climbing, perennial vine, largely ...

Essential oils from five species of medicinal and food plants were tested as mycelial growth inhibitors against five important pathogenic fungal species that cause stem, leaf and ear diseases of cereals. An agar dilution method was used to determine the inhibitory effect and effective dose of...

This paper presents some innovative adaptation strategies for the management of increased pest populations (due to climate change) in the Caribbean, focusing on modification of integrated pest management system. These include the use of (i) legislation to prevent establishment of potentially...

4β-Hydroxywithanolide E is a compound with antifeedant activity against certain species of insect herbivores. This compound has been found in roots, leaves, calyxes, and fruits of Physalis peruviana plants. In this study, we quantified by HPLC the concentration of 4β-hydroxywithanolide E in...

In view of the recently increased interest in developing botanical pesticides as an alternative to synthetic pesticides, this investigation was carried out to examine the insecticidal potentials of the Zanthoxylum Zanthoxyloides (Lam.) Waterm. (Rutaceae) Root Bark Powder against Seed Beetle, ...

Use of synthetic pesticides in developing countries is not only limited by their being expensive but also the small (uneconomic) fields whose limited production costs cannot offset costs of agricultural implements like agro-chemicals. Subsistence farmers, therefore, have no choice but to use local...
