Abstract:
Morphology of the scent (pheromone) glands is the first and basic step in understanding the mechanism of working of this highly evolved and integrated system of communication in insects. Leptocoris augur contains a pair of large and distinct symmetric exocrine dorsal abdominal glands (DAGs) found in the dorsal abdominal segments. The glands are simple, voluminous, sac-like and bright orange that turn brown and downsized with age. They are invested with a large and dense network of trachea and open to the exterior via minute slit shaped openings in the form of ostioles that remain permanently open to the outside. The functional specificity of these glands can be associated with the activities ranging from aggregation to sexual behaviours like courtship and mating. The mating is not restricted to a specific season, being distributed all-round the year; however, the insect prefers low and humid temperature for mating and they can be seen congregating in huge numbers when the hot summers subside and the rainy season arrives. We didn’t observe any considerable variation in size of these glands with respect to the body size in between the instars and the adults. Further, there were no significant difference between males and females in terms of the size of these DAGs.

Abstract:
Following their establishment in new communities, invasive species may cause evolutionary changes in resident native species. This is clearly true for phytophagous insects, which may adapt rapidly when utilising abundant and widespread introduced hosts. The balloon vines Cardiospermumhalicacabum and C.grandiflorum were introduced to South Africa approximately 100 years ago and are classified as minor and major weeds, respectively. Here we assess the potential evolutionary impact of these vines on native Leptocoris soapberry bug populations in Kruger National Park (KNP), using phylogenetic and morphometric analyses. We found that soapberry bugs associated with C.halicacabum are genetically and morphologically distinct from those associated with C.grandiflorum. This suggests that native soapberry bugs in KNP exhibit some degree of host preference, indicating that these vines may have had significant evolutionary consequences for these insects. The proboscis length of soapberry bugs feeding on C.halicacabum closely matched fruit size, often being longer than fruit size at the population level. These soapberry bugs are therefore well-suited to feeding on this introduced plant species.

Abstract:
Entomopathogenic fungi from the lowland soil of South Sumatera and their potential as biocontrol agents of Stink Bug (Leptocorisa oratorius (F.)). The purpose of this research was to explore and examine the potential of soil borne entomopathogenic fungi from South Sumatera as biological agents of Leptocorisa oratorius (F). Soil used for trapping entomopatogenic fungi, was taken from five locations in South Sumatera. Percentage of nymph mortality was analyzed by using analysis of variance and arranged in Completely Randomized Design. LT50­ of nymph mortality was determined with Probit Analysis. Entomopathogenic fungi found in this research were Beauveria bassiana and Metarhizium sp. Stink bug mortality due to B. bassiana isolates reached 40-73.3% and Metarhizium sp. reached 56.7-70%. The results showed that Metarhizium isolates were more virulent than B. bassiana isolates. The viability of B. bassiana conidia did not decrease during sub-culturing. Sub-culturing did not influence the mortality of stink bug nymph but it prolonged the LT50­ of the stink bug.

AbstractThe biology of the predacious cricket Metioche vittaticollis (Stål) collected from rice in the Philippines was studied in the laboratory and greenhouse. The cricket preyed on the eggs of a range of insect pests of rice including Chilo suppressalis (Walker), Cnaphalocrocis medinalis (Guenée), Hydrellia philippina Ferino, Mythimna separata (Walker) and to a lesser extent on the eggs of Leptocorisa oratorius (F.). There was no predation on the eggs of Scirpophaga incertulas (Walker).

Abstract:
The boxelder bug, Boisea trivittata (Say), is a pest because large numbers congregate on and in buildings, causing concern among homeowners. More knowledge of effective insecticides, seasonal abundance of the pest, and concerns of the affected homeowner will help to reduce the impact of the insect in urban areas. Field-collected adults and nymphs exposed to latex-painted surfaces treated with 0.1% cypermethrin, 1.0% diazinon, 0.25% bendiocarb, 0.25% chlorpyrifos, and 1.0% propetamphos resulted in more than 70% mortality with all insecticides up to 3 d after treatment for adults, and 7 d after treatment for medium-and large-sized nymphs. Fewer than 50% of homeowners surveyed thought boxelder bugs were a serious pest. Homeowners had little knowledge about the source of infestations from host trees. Residents reported spending $22.42 (median) to control boxelder bugs, but were willing to spend $45.00 (median). Residents tolerated more bugs outside (median=63) than they would inside (median=8) their house. From April to December, 1988, boxelder bug populations were sampled outdoors in urban areas. First generation nymph and adult populations peaked during June and July. Fall generation nymph and adult populations were abundant on the ground and trees from August to September, but not on residences. Movement to the ground and surfaces of buildings occurred in October, and adults peaked in numbers in mid November. Temperature profiles on residences and behavioral observations indicated that boxelder bugs found on host trees orient toward sunlight; adults were found in greater numbers on surfaces with higher mean temperatures than other substrates.

Leptocoris abdominalis is ingested by eating Koelreuteria henryi Dummer in Taiwan. Leptocoris abdominalis in Taipei is very common, also they often cluster together. My research analysed COI sequences to construst Leptocoris abdominalis’ population structure and discussed their life history. The results showed that Leptocoris abdominalis’ haplotype diversity are very high; however, their nucleotide diversity are low. That means Leptocoris abdominalis has experienced bottleneck and after that they were dispersed in Taipei. To conclude, Leptocoris abdominalis is a species that adapt in Taipei, and slso they has experienced bottleneck once before.

Life history of Leptocoris abdominalis (F.) was investigated by feeding bugs with seeds of Taiwan golden rain tree (Koelreuteria formosana Hayayta) under different temperatures, namely 15, 17, 20, 25, 28 and 30 oC, and room temperature (24 ± 4oC). The results showed that it takes 51.7 ± 5.7 days for eggs developing to adults and sex ratio of female:male was 1:1.45. Developmental duration for each stage was about 6~8 days with eggs duration being longer (11 days) at room temperature. The body color of new hatched nymph was bright red, and black wing-buds appeared on the back of third instar nymph. The genitalia of adults can only be observed after their emergence. The longest egg duration was 18.7 ± 1.6 days at 15oC while the shortest was 5.2 ± 0.8 days at 30oC. However, there was no individual can survival to adult at both 15 and 30oC. For other 4 tested temperatures, the longest time needed to develop from eggs to adults was at 17oC (109.4 ± 44.3 days) and the shortest one was at 28oC (34.9 ± 13.9 days). Thus, the most suitable temperature for rearing L. abdominalis is 20 to 28oC and the higher the temperature is, the shorter generation time they have. The longevity of female is longer than that of male. The sex ratio of female and male ranged from 1 : 1.2 to 1 : 1.5 at temperatures of 17, 20, 25, and 28oC. The critical developmental temperature (development zero) was estimated as 13.6 ± 2.2oC and the Degree-Day accumulations for this bug was 420.3 ± 92.3 DD. Mating tests showed the highest mating frequency occurring when put 1 female and 2 males together. Female seems play the leading role and decide whom it wants to mate. Oviposition tests showed that females prefer laying eggs on gauze, following on capsule leaves in laboratory test. It coincided with the observation of bugs prefer ovipositing on coarse walls, tree bulk, and capsule leaves in the field. The comparison of eggs produced between single pair and cluster treatments showed cluster treatments have more eggs produced (23.9 ± 5.6 eggs/♀) than that of single pair. Although number of eggs produced by single pair can be as high as 60 eggs/♀ while some of them did not lay any eggs. Hatching rate of eggs was highest (93.0 ± 0.8%) at 28oC and which almost the same as that at room temperature (88.5 ± 5.4%). The lowest egg hatching rate was 45.0 ± 1.3% at 15oC. The higher the temperature is, the higher the hatching rate is. However, the hatching rate decreased when temperature higher than 30oC. L. abdominalis uses the seeds of Koelreuteria formosana as its major food and its population is changing through the seasonal phenology of this tree. The population peak of L. abdominalis is reaching at the time of fruits dropping in each year. When new buds germination during March and April, the bugs always leave the trees and alternatively feed on the fruits of balloon vines (Cardospermum halicacabum L.). The population of L. abdominalis dramatically decreased during this period. Clustering behavior observation showed that the first to forth instar bugs are significantly clustering together in the field. The fifth instar and adult bugs always act independently. Young nymphs prefer to cluster at the basis of trees while aged nymphs and adults prefer stay on trunk and leaves of tree. Population of bugs was found positively correlation to seed number. Moreover, piercing and sucking of L. abdominalis on K. formosana did not cause the death of tree, on which new buds still can germinate at March and April for each year.

Heartseed vine plant（Cardiospermum halicabum） has a hard seed coat to prevent the insect attack, and causing low germination rate. After feeding by small red stinkbugs（Leptocoris augur）, the seed germination rate of heartseed vine was 2.64-4.32 fold increased compared to the control group. With the increasing water permeability of the testa, it also raised the germination rate of the seeds. The feeding of small stinkbugs has the same effect with man-made injury. The seed of heartseed vine provides a specific food source for small red stinkbugs. Meanwhile, after the fed by small red stinkbugs, it leads a significant increase on seed germination rate of heartseed vine. This indicates a mutualism relationship was developed between small red stinkbugs and heartseed vine. Both small red stinkbugs and red stinkbugs (Leptocoris abdominalis), belonged to Rhopalidae, are attacking seed of Sapindaceae（Koelreuteria tree and heartseed vine）. Koelreuteria tree (Koelreuteria elegans) mature pods split the consequences, but heartseed vine are pod-coated,Stinkbug feeding a certain length of time required to sucking mouthparts into the seed. Compared by measuring the mouthparts length of two different stinkbugs, small red stinkbugs significantly greater than red stinkbugs, but body length red stinkbugs are significantly greater than small red stinkbugs. However, the two different seed feeding Rhopalidae bugs mouthparts length and length are not significant. These differences may be caused by food. Currently observed small red stinkbugs have been lying on the ground and in the living Heartseed vine lying on the ground between the tree and Koelreuteria elegans two kinds of movement of life, long-winged type with short wings and a combination of patterns, environmental factors, natural selection role to an evolutionary stable strategy.
