HOSTS Date palms. DESCRIPTION The adults are small with fringy wings brownish color, marked by a grey longitudinal Adult Moth central stripe on the forewings. Wingspan 10-14 mm Larvae Orange to orange-brown. One larva damages several fruits. Eggs 0.7 mm in diameter and yellow with a pearly sheen It is one of the most important pests on date palm that may cause more than 50% loss of the crop. There are three generations per year in the United Arab Emirates. The LIFE HISTORY first larvae appear in April and damage newly formed fruits. They are dormant from August to March of the following year, resting between the bases of the terminal fronds. Pupation takes place in March and adults emerge in April. MONITORING INFORMATION LURE, FIELD LIFE Grey rubber septum, 8 weeks Baited Plastic Delta traps TRAP TO USE (lures sold separately) Place 1-2 baited traps per ha. Place traps 6-8 m above the ground. Check the trap MONITORING STRATEGY weekly. Replace the lure and sticky liner every 30 days. Several cultural practices may reduce injury by lesser date moth. Sanitation and mechanical fruit protection can substantially reduce damage caused by this pest. CULTURAL & PHYSICAL Removal of fall fruit and pruning of bunch remain after harvest will reduce future CONTROL populations. Bunch covering with light cloth will prevent current infestation by lesser date moth.

The efficiency of the parasitoids is affected by many environmental factors including tempera- ture. The effect of different temperature regimes on some biological characteristics of T. evanescens was investigated when reared on the egg B. amydraula under laboratory conditions. The longest life span was 35 days recorded at 15°C while the shortest one was 7 days at 33°C. The optimum temperature for the development of this parasitoid ranged between 22 and 27°C. The upper development threshold temperature was 38.4°C and the lower was 11.14°C. Results also showed that the highest parasitism rate was 94.4% recorded at 25±2°C. Adult emergence and female longevity were also influenced by temperature. The feasibility of the results in mass production and the use of the parasitoid for the control of lesser date moth also discussed.

This study aimed to set a new strategy by using six parasitoids and predators, i.e. Trichogramma sp., Bracon sp., Goniozus sp., Chrysoperla sp., Coccinella sp. and Orius sp. to trap the different pests’ stages in El-Bahariya and Siwa Oases’ palm plantations. By the end of the season of each pest, A. sabella and V. livia infestation% in El-Bahariya control farm recorded 92.1 and 51%, respectively, while B. amydraula recorded 40.2%. Infestation declined when natural enemies were released, i.e. 0, 1.1 and 1.1%, for the three pests, respectively. In Siwa, infestation in control recorded 52, 40.2 and 43%, while dropped in treatments to 0, 2 and 2 %, for the three pests, respectively. Using this combination of natural enemies was effective and it is recommended to integrate this strategy in palm plantations IPM programs in Egypt, mainly, in protectorates, where using pesticides is prohibited.

Periodical Lesser Date Moth Infestation on Intact and Dropped Fruits
Sarhad J. Agric. Vol. 26, No. 3, 2010 393 PERIODICAL LESSER DATE MOTH INFESTATION ON INTACT AND DROPPED FRUITS M.K. KAKAR, S. M. NIZAMANI, M. A. RUSTAMANI and R.D. KHUHRO Faculty of Crop Protection, Sindh Agriculture University, Tandojam – Pakistan. ABSTRACT Lesser date moth, Batrachedra amydraula (Meyr) is a very important insect pest of date. It attacks the date fruits and causes heavy losses. There are three generations of this insect per year. It appears in April, while the fruits are in unripe stage and remains till September. The study was carried out on Aseel variety of date palm, to monitor the peak period of infestation of the insects both on intact fruit as well as dropped fruit on four locations viz: Kot Digi, Kingri, Khairpur and Therhi district Khairpur, Sindh Province, Pakistan. The observations were recorded on weekly basis from 1st April to the end of August during 2007 and 2008. It was concluded that the attack of this insect was on its peak during the months of June. It was also found that the attack on dropped dates was more than on intact fruit. The attack during peak period reached 10-12% in intact fruits and 17-18% in dropped fruits. The infestation percentage decreased during August and September, 2007-08. Key Words: Date Palm, Lesser date moth, phenology and infestation. Citation: Kakar, M.K., S.M.

Monitoring and Mass-Trapping Methodologies Using Pheromones: the Lesser Date Moth Batrachedra Amydraula
Bulletin of Entomological Research (2018) 108,58–68 doi:10.1017/S0007485317000487 © Cambridge University Press 2017 Monitoring and mass-trapping methodologies using pheromones: the lesser date moth Batrachedra amydraula A.

Previously, detection and monitoring of the pest was inaccurate due to high costs of sampling with lifting machines. We report a practical system for detection and monitoring of LDM based on pheromone traps and relevant models. Dose–re- sponse experiments with LDM pheromone traps indicated a 1 mg lure is optimal for monitoring. Delta traps with adhesive covering their entire inner surface gave the highest captures while trap colour was unimportant. Sampling pheromone traps throughout the night indicated male flight began at 1:00–2:00 and reached a peak 2 h before sunrise. Monitoring traps exposed all year long in Israel revealed three generations with different abundance. Trapping transects in a date plantation in- dicated interference from a monitoring trap became minimal at distances >27 m away. Inter-trap distances closer than this may lower efficiency of monitoring and mass trap- ping in control programs. Our estimate of the circular effective attraction radius (EARc) of a 1 mg delta trap for LDM (3.43 m) shows this bait is among the most attractive com- pared with baits for other insects.

The present review provides a basic summary of the utilization of *Corresponding address: semiochemicals for controlling insect pests. Two main topics were explored in this study. [email protected] The first topic focuses on a description of semiochemicals and their types (pheromones and allelochemicals). Pheromones represent an intraspecific communication amidst members of the same species. Allelochemicals, produced by individuals of one species, modify the behavior of individuals of a different species (i.e. an interspecific effect). Allelochemicals include different informative molecules such as: allomones, kairomones, synomones, an- timones and apneumones. The second topic focuses on the application of semiochemicals in IPM programs. Different semiochemicals are included in integrated pest management programs in various ways such as monitoring, mass trapping, attract-and-kill, push-pull, and disruption strategies. Pheromones are promising and can be used singly or in integra- tion with other control strategies for monitoring and controlling insect pests in agricultural systems.

Date Palm Arthropod Pests and Their Management in Israel
ENTOMOLOGY D. Blumberg (2008) Phytoparasitica 36(5):411-448 REVIEW: Date Palm Arthropod Pests and Their Management in Israel Daniel Blumberg1 This review summarizes the current knowledge on the distribution, natural history, economic importance and management of 16 major species of date palm pests in Israel. Another 15, rarely occurring, pest species are also identified. Research on the date palm pests in Israel was initiated against a background of severe outbreaks of scale insects in the late 1950s. These outbreaks were caused mainly by unrestrained use of organophosphates. This situation led to the gradual development of an Integrated Pest Management (IPM) program, which was implemented first against scale insects and later against fruit pests. The IPM approach resulted in successful control of the scale insects, up to the present, whereas agrotechnical and crop management procedures, including covering the fruit bunches with plastic nets and early harvesting of several date cultivars, were successfully applied to achieve efficient control of the fruit moths. In addition, the use of chemical compounds in date plantations was drastically reduced and restricted to heavy foci of pest infestation. In time, microbial control, mainly application of Bacillus thuringiensis products against the lesser date moth, and the use of pheromone traps for monitoring and controlling red palm weevil, enabled further reductions in the use of synthetic insecticides. The overall change in pest management also significantly improved the preservation of natural enemies of the pests in the plantations. Whereas in the 1950s the major problems were caused by the parlatoria date scale and the green scale, in the early 2000s the key pests in date plantations in Israel are the lesser date moth and sap beetles in most of the date-growing areas, and spider mites which are restricted to the Arava Valley.
