Tomato (Solanum lycopersicum L.) is a hermaphrodite plant and capable of auto pollination. However it still need pollinators to maximize pollination success. This research was aimed to determine the diversity, foraging activity of pollinator bees and its effectiveness on seeds and fruits formation of tomato. Scan sampling method was used to determine the diversity of pollinators and focal sampling method was used to observe visiting behavior of the bees. We conducted two experiments i.e., screen caged plants and open plants to compare the effect of the bee pollinators on fruits and seeds set formation. Results showed that eleven species of bees were found, i.e., Megachile conjuncta Smith, Megachile fulfifrons Smith, Megachile unbripennis Smith, Xylocopa confusa Latreille, Xylocopa latipes Drury, Xylocopa caerulea Fabricius, Ceratina cognata Latreille, Nomia quadridentata Bingham, Amegilla cyrtandrae Lieftinck, Amegilla burneensis Friese, and Apis cerana Fabricius. Three species of bees were dominant, i.e., X. confusa, A. cyrtandrae, and C. cognata. Bee, X. confusa visited more flowers per minute, followed by A. cyrtandrae and C. cognata. The longest species visiting in plants were C. cognata, followed by X. confusa and A. cyrtandrae. Bee pollinators increase 8.92% of fruiting, 43% of fruit size, 189% of number of seeds per fruit, and 355% of weight of seeds of tomato plants.

A parasitoid, Anagyrus lopezi (De Santis) (Hymenoptera: Encyrtidae) was introduced from Thailand into Indonesia in early 2014 to control the cassava mealybug Phenacoccus manihoti Matile-Ferrero (Hemiptera: Pseudococcidae). To determine its potential uses and effect on non-target species, behavioural observation of the parasitoids were made on four species of mealybugs, i.e. P. manihoti, Paracoccus marginatus Williams-Granara de Willink, Pseudococcus jackbeardsleyi Gimpel-Miller, and Ferrisia virgata Cockerell (Hemiptera: Pseudococcidae). For that purposes, a set of tests were conducted which includes host susceptability, preference, and suitability. Tests were conducted by exposing a female parasitoid to 3rd instar nymphs of each mealybug species in a petri dish. For susceptability test, parasitoid A. lopezi encounterend P. manihoti more often (13.70 ± 7.18 visits per 30 minutes) as compared to P. marginatus (985 ± 10.24), P. jackbeardsleyi (6.60 ± 3.62), and F. virgata (5.75 ± 4.09). So did ovipositor probing occurred more on P. manihoti (8.20 ± 5.68 probes per 30 minutes) than on P. marginatus (0.70 ± 1.84), P. jackbeardsleyi (0.35 ± 0.68), and F. virgata (0.10 ± 0.45). For preference test, host encounter and ovipositor probing by the parasitoid were more common on P. manihoti as opposed to other mealybug species. Out of four mealybug species tested, P. manihoti was the only suitable host for parasitoid development, with the number of progenies emerged 7.40 ± 2.17 individuals per 3 female parasitoids exposed in 24 hour. Host specifity exhibited by parasitoid A. lopezi may prevent adverse effect to other mealybug species inhabiting cassava fields.

Aedes aegypti (Linnaeus) (Diptera: Culicidae) is the main vector of dengue fever. In Indonesia, insecticides, especially pyrethroids, such as permethrin, have been effectively used to control Ae. aegypti. Notwithstanding that permethrin has been used since 1980s, information regarding the status and development of resistance of Ae. aegypti to permethrin is still limited and need further update. This study was conducted using the WHO standard test method. The aims was to determine the resistance status, and changes in resistance level of four field strains (Palu, Makassar, Bandung, Bogor) and susceptible strain (VCRU) of Ae. aegypti after the selection with permethrin for five generations. The results showed that resistance status of all field strains to permethrin were considered as high. The value of RR50 ranged between 10.5 to 25.7 fold. Bandung strain had the highest value of RR50 (22.5 fold), while Makassar strain had the lowest value of RR50 (10.5 fold). The fifth generation (F5) of five selected Ae. aegypti strains had the level of resistance 5 to 18 times higher than their parental. Knowledge of resistance status in a given area accompanied with the understanding about the development of resistance can be used to design a better vector management.

Cylas formicarius (Fabricus) (Coleoptera: Curculionidae) is one of the major pest on sweetpotato which can cause yield lost up to 100%. The objective of this study was to obtain the effective and efficiency control technique of sweetpotato weevils. The research was conducted on June–October 2014 at Muneng Research Station, Probolinggo, East Java, using randomized block design, five treatments and three replicates. The treatments consisted of immersion of sweetpotato cuttings in the suspension of conidia Beauveria bassiana (Bals.) Vuill. for 30 minutes before planting; application of suspension of conidia B. bassiana on soil at 2, 4, 6, 8, 10, and 12 weeks after sowing (WAS); immersion of sweetpotato cuttings in the suspension of conidia B. bassiana for 30 minutes before planting combined with application of suspension of conidia B. bassiana on soil at 2, 4, 6, 8, 10, and 12 WAS; application of chemical insecticide every week; and control. Analysis of variance showed that the application of various control technique significantly lowered the population of larvae and imago of C. formicarius and the level of tuber damage. The population level found on all treatments ranged from 1–4 eggs/plant, 1–19 larvae/plant, 0–0.2 pupae/plant and 0–4 imago/plant. The weight of tuber was 571–700 g/plant with the level of damage 6–53%. Low level of damage was found in the aplication of suspension of conidia B. bassiana on soil at 2, 4, 6, 8, 10, and 12 WAS which were 6%. Application of suspension of conidia B. bassiana on soil at 2, 4, 6, 8, 10, and 12 WAS can suppress the population of C. formicarius on tuber and reduce the level of damage up to 48%.

Confirmation that Helopeltis species attacking cacao in Yogyakarta is Helopeltis bradyi Waterhouse, not Helopeltis antonii Signoret (Heteroptera: Miridae) Susi Melina; Edhi Martono; Y. Andi Trisyono

Helopeltis antonii Signort (Heteroptera: Miridae) has long been reported to attack cacao and other host plants in Java. A recently published literature review refuted this idea and offered morphological evidence suggesting that this attacker is actually H. bradyi Waterhouse. However, through the present, local reports still identify attacks as coming from H. antonii. To confirm which of these two species is implicated in cacao damage, we conducted an examination of the external morphology, genitalia and the biology of Helopeltis sampled from infested cacao plants in Yogyakarta. 42 females and 9 males, sampled from 3 different locations, were observed to be morphologically similar to H. bradyi, especially with regard to the pale band on the base of all femora, the knife-shaped male lobal sclerite, and the presence of a ‘Y’ shaped junction on the posteriorly fused female genital chamber. The duration of the life stages (in days) of the laboratory-reared insects were: 7−11 (eggs), 12−19 (nymphs), 9−44 (female) and 16−54 (male) d, measurements which fall within the ranges of the parameters usually reported locally for H. antonii, with the exception of male adult life stages which are longer than the aforementioned reports. Morphological changes were observed during all stages of development, including within adult stages. In female adults specifically, external morphology and genital development proceeded continuously until the insects reached the full-grown condition, characterized by stable color, and fully sclerotized genital chamber. Our preliminary study of the morphology and development of lab-reared insects descended from individuals infesting cacao fields, indicated the presence of H. bradyi instead of H. antonii in Yogyakarta, and therefore stipulated a need to review the existence of the latter in Indonesia.
