Application of Essential Oils of Ocimum gratissimum and Cymbopogon citratus as Bioinsecticides for the Management of Two Major Biting-Sucking Insects (Bemisia tabaci Gennadius and Jacobiella fascialis Jacobi) and the Improvement of Seed and Fiber Quality of Cotton Plants in Ivory Coast.

In recent years, in all cotton production areas in Ivory Coast, whitefly (Bemisia tabaci) and jassid (Jacobiella facialis), two biting sucker insects were causing depreciation of quality of the cottonseed and fiber obtained at harvest. However, the excessive use of synthetic chemical insecticides against these pests presents a danger for the sustainability of the production system. This study aims to evaluate the insecticidal efficacy of essential oils of Ocimum gratissimum and Cymbopogon citratus on B.

Article Synopsis
- Essential oils from Ocimum gratissimum and Cymbopogon citratus were tested as eco-friendly alternatives to chemical pesticides in cotton fields in Côte d'Ivoire, demonstrating effective pest control.
- Key compounds in the essential oils were identified, with O. gratissimum showing insecticidal activity against various pests and C. citratus being particularly toxic to whiteflies while supporting beneficial insects.
- The essential oils also exhibited properties that inhibit certain enzymes related to pest management, suggesting their potential for safe and effective use in sustainable cotton cultivation.
Objective: To estimate the predictive role of faecal haemoglobin (f-Hb) concentration among subjects with faecal immunochemical test (FIT) results below the positivity cut-off for the subsequent risk of advanced neoplasia (AN: colorectal cancer-CRC-or advanced adenoma).
Design: Prospective cohort of subjects aged 50-69 years, undergoing their first FIT between 1 January 2004 and 31 December 2010 in four population-based programmes in Italy.
Methods: All programmes adopted the same analytical procedure (OC Sensor, Eiken Japan), performed every 2 years, on a single sample, with the same positivity cut-off (20 µg Hb/g faeces).
Article Synopsis
- - The concept that noncrop habitats can improve pest control while supporting biodiversity has gained traction, but the results are inconsistent across different studies.
- - An analysis of 132 studies showed that while landscape composition often influenced pest and natural enemy populations, the outcomes varied significantly, leading to no definitive improvement in overall pest management.
- - The findings suggest that noncrop habitats do not uniformly enhance pest control, indicating a need for better guidelines to help farmers understand when habitat conservation will actually benefit crop yields.
Mother's Age and Hatching Phenology Strategy of Heterocypris incongruens (Crustacea: Ostracoda) in Unpredictable Environment.

We report experimental evidence of egg polyphenism in clonal lineages of Heterocypris incongruens from an ephemeral pond on a Mediterranean Island (Lampedusa, Italy). In controlled laboratory conditions, clonal females produced three different kinds of eggs: (i) resting and desiccation-resistant eggs, (ii) nonresting eggs that hatched gradually within 2 month hydroperiod, and (iii) nonresting delayed development eggs that hatched synchronously. Clonal females showed a diversified bet-hedging strategy to spread risk of reproduction in ponds with unpredictable hydroperiod.
