AbstractTo use gizzard analysis quantitatively, in the assessment of bird predation on insect populations, information is needed on the time that identifiable remains of the prey can be found in the gizzard and on the rate at which these remains disappear. The digestion rate, measured by the disappearance of mandibles or cremasters, has been studied for larvae and pupae of the spruce budworm, Choristoneura fumiferana (Clem.), when eaten by the olive-backed thrush, Hylocichla ustulata swainsoni (Tschudi).

To date, control strategies used against insect pest species are based on synthetic insecticide applications. In addition, the efficacy of these treatments could be decreased due to insecticide resistance in insect populations. Also, the irrational use of chemical control strategies has negative consequences of non-target organisms and threatening human health. Designing nanomaterial for pest insect control is a promising alternative to traditional insecticide formulations. In particular, it has been proven that silica nanoparticles have the potential for molecules delivery, release control improvement and also their toxicity as insecticide alone. In this work, we summarized the state of knowledge on silica nanoparticles (SiNPs) used in pest insect management. Besides, aspects of their synthesis, mode of action, and toxic effects on non-target organisms and environment are reviewed.

This chapter explores chemical control strategies. Despite promising recent developments in insect-resistant cultivars, biological control strategies, and improved cultural practices, turf managers in the United States often find that circumstances dictate the use of a traditional insecticide. The pressure to use insecticides to manage turf insect populations often comes from clients or golfers who have come to expect and demand virtually pest-free turf and assume that using an insecticide will produce the desired result. When heavy infestation of a pest insect is sudden and unexpected, there often is no alternative but to depend on a traditional insecticide to reduce the population in a timely manner. The chapter then considers the effect of insecticides on nontarget organisms, as well as the environment fate of pesticides.

ABSTRACT The quality and quantity of rice as a source of food for most of Indonesian people are closely connected with the activity of insect pests in Warehouse. This study aims to determine the species and insect pests populations on Rice at Traditional and Modern Warehouse in Province of Gorontalo. The study used a survey method shelter/rice warehouse in Mootilango district, Boliohuto District, and Tolangohula district, Gorontalo province. Sampling was conducted in a purposive sampling is to take a sample of the suspected rice pests. Sampling was carried out 4 times with a time interval of 2 weeks. The research found six species of insect pests on rice commodities in Gorontalo regency consisting of 5 species of the order Coleoptera and 1 type of the order Lepidoptera. The results show that the identification of insect pests found are Sitophilus oryzae (Coleoptera; Curculionidae), Tribolium castaneum (Coleoptera: Tenebrionidae), Carpophilus hemipterus (Coleoptera: Nitidulidae) Oryzaephilus sp. (Coleoptera; Silvanidae), Ahasverus sp. (Coleoptera; Cucujidae), Corcyra cephalonica (Lepidoptera; Pyralidae). Average highest pest insect populations, respectively S. oryzae (54.60 individuals), Tribolium sp. (13.85 individuals), Oryzaephilus sp. (4.52 individuals), Ahasverus sp. (3.42 individuals), Corcyra sp. (2.42 individuals) and C. hemipterus (6.94 individuals), while the highest populations of insect pests found in traditional 16.40 modern warehouses 12.34 individual Keywords : insect pests, rice, traditional and modern werehouse

Beneficial insect populations and the services that they provide are in decline, largely due to agricultural land use and practices. Establishing perennial floral plantings in the unused margins of crop fields can help conserve beneficial pollinators and predators in commercial agroecosystems. We assessed the impacts of floral plantings on both pollinators and arthropod predators when established adjacent to conventionally managed commercial potato fields. Floral plantings significantly increased the abundance of pollinators within floral margins compared with unmanaged margins. Increased floral cover within margins led to significantly greater pollinator abundance as well. The overall abundance of arthropod predators was also significantly increased in floral plantings, although it was unrelated to the amount of floral cover. Within adjacent potato crops, the presence of floral plantings in field margins had no effect on the abundance of pollinators or predators, although higher floral cover in margins did marginally increase in-crop pollinator abundance. Establishing floral plantings of this kind on a large scale in commercial agroecosystems can help conserve both pollinators and predators, but may not increase ecosystem services in nearby crops.
