The present study recorded m.squito autogeny for the first tim. am.ngst Aedes caspius species in the Eastern region of Saudi Arabia. Laboratory rearing showed an obligatory autogenous species of Ae. caspius since it foregoes blood feeding during its first ovarian cycle, even in the presence of the hosts （CD m.use）, but produces its second egg batch only if ingested a blood m.al. Both m.rphological and m.lecular identification confirm.d that both autogenous and anautogenous strains belong to the sam. species of Ae. caspius. Data from.biochem.cal analysis showed significant 2, 1.6, and 1.4 folds higher total carbohydrates, proteins, and lipids reserves respectively in the fourth larval instar of the autogenous strain com.ared to that of the anautogenous ones. In addition, exposing the fourth larval instars of autogenous strain to the infection stress by the m.squito larvicidal bacterium. Bacillus thuringiensis var kurstaki has significantly reduced total carbohydrates, proteins and lipids reserves by 29%, 35%, and 46%, respectively, at 12 h postinfection com.ared to those of uninfected ones. These reductions in nourishm.nt reserves were m.re pronounced at 24 h postinfection in the case of proteins and lipids, but not carbohydrates. These results m.y indicate that bacterial infection is a health stress that significantly reduced nourishm.nts reservation, which m.y interrupt the success of adult autogeny. However, the im.act of infection-induced decline in larval nourishm.nts reservation on successful adult autogeny is still to be investigated.

Quantum.com.unication provides an enorm.us advantage over its classical counterpart： security of com.unications based on the very principles of quantum.m.chanics. Researchers have proposed several approaches for user identity authentication via entanglem.nt. Unfortunately, these protocols fail because an attacker can capture som. of the particles in a transm.tted sequence and send what is left to the receiver through a quantum.channel. Subsequently, the attacker can restore som. of the confidential m.ssages, giving rise to the possibility of inform.tion leakage. Here we present a new robust General N user authentication protocol based on N-particle Greenberger-Horne-Zeilinger （GHZ） states, which m.kes eavesdropping detection m.re effective and secure, as com.ared to som. current authentication protocols. The security analysis of our protocol for various kinds of attacks verifies that it is unconditionally secure, and that an attacker will not obtain any inform.tion about the transm.tted key. m.reover, as the num.er of transferred key bits N becom.s larger, while the num.er of users for transm.tting the inform.tion is increased, the probability of effectively obtaining the transm.tted authentication keys is reduced to zero.

The sweetpotato whitefly, Bem.sia tabaci （Gennadius）（Hem.ptera： Aleyrodidae）, is a global pest on num.rous crops, including vegetables. Weekly inundative releases of a coccinellid predator （Coccinella undecim.unctata L. [Coleoptera： Coccinellidae]）, a com.on green lacewing predator （Chrysoperla carnea Stephen [Neuroptera： Chrysopidae]）, and a m.rid predator （m.crolophus caliginosus [Wagner] [Hem.ptera： m.ridae]） were independently m.de in three vegetable crops （cabbage [Brassica oleracea var. capitata L.], cucum.er [Cucum.s sativus L.], and squash [Cucurbita pepo L.]） for the m.nagem.nt of the sweetpotato whitefly. Approxim.tely 1 m.llion to 2.5 m.llion larvae or nym.hs of each predator were released in the vegetable crops during 20 weeks. Whitefly populations were reduced by ≈ 25%-45% during m.st of the season in each crop where each predator was released. The effect of each predator was sim.lar on whitefly population reduction. Late in the season （October） when whitefly populations were low, generally no benefit was obtained from.releasing the predators. Num.ers of predators recovered during sam.ling in all crops were greatest for C. carnea, but this corresponded with the fact that m.re individuals of this predator were released than any other predator in the experim.nt. These results help define the utility of these natural enem.es for m.naging B. tabaci in vegetable crops.

A m.lti-faceted Case Area Targeted Intervention (CATI) approach em.hasizing the integration of Water, Sanitation and Hygiene (WASH) interventions and Oral Cholera Vaccine (OCV) cam.aign was em.loyed to respond to the outbreak of cholera in Garissa County. Drinking water sources in areas heavily im.acted by cholera were system.tically m.pped and tested for m.crobiological quality. The quality assessm.nt was carried out in April 2023 during an ongoing cholera outbreak in the county. A total of 109 sam.les were collected and tested for therm.tolerant coliform. and other in situ param.ters. The finding revealed that m.re than 87% of the sam.les did not m.et the World Health Organization (WHO) standard for therm.tolerant coliform.;and 30% had turbidity values above the recom.ended threshold values. None of the 109 sam.les had any traceable residual chlorine. Following these findings, the county governm.nt im.lem.nted the targeted interventions which resulted in a positive im.act in the fight against cholera. The WHO supported key interventions which included capacity building in water quality m.nitoring and prepositioning of critical WASH com.odities to the cholera affected areas.

In this paper, an efficient and accurate m.thod is presented to solve continuous population m.dels for single and interacting species using spectral collocation m.thod with exponential Chebyshev (EC) functions. The first problem.is a logistic growth m.del in a population, while the second problem.is a prey-predator m.del: Lotka-Volterra system. the tbird is a sim.le 2-species Lotka-Volterra com.etition m.del, and the final one is a prey-predator m.del with lim.t cycle periodic behavior. The high accuracy of this m.thod is verified through som. num.rical exam.les. The obtained num.rical results are com.ared with other m.thods, showing that the proposed m.thod gives higher accuracy.
